Abideen claims to have placed a 45 second video clip on a single sheet of paper, with the possibility of up to 450GB on the horizon - Image courtesy Arab News
Rainbow technology still in the works but holds promise

According to a report from the Arab News, a university technology student named Sainul Abideen has invented a method of storing massive amounts of digital data on a plain piece of paper that he claims could store many times the capacity of the best Blu-ray or HD-DVD discs. In fact, Abideen says that his Rainbow technology can enable him to store from 90 to 450GB on a piece of paper. As far as a real life demonstration of a 450GB paper goes, the technology still needs development.

Abideen, who hails from the Kerala, India, claims that that his Rainbow system is better than a binary storage because instead of using ones and zeros to represent data, Abideen uses geometric shapes such as squares and hexagons to represent data patterns. Color is also used in the system to represent other data elements. According to Abideen, all that's required to read the Rainbow prints is a scanner and specialized software.

The reporter at Arab News claims to have seen 450 pages of fully printed foolscap being stored on a 4-square inch piece of Rainbow paper. The reporter also claimed that he was shown a 45-second video clip that was stored using the Rainbow system on a plain piece of paper. Interestingly, 45-seconds of video isn't a lot, and if the Rainbow system can store up to 450GB, then we need to be watching full length high-definition videos from a piece of paper.

One of the major advantages of the Rainbow system is the fact that it should cost a lot less to produce than typical polycarbonate DVD and CD discs. Abideen claims that huge databanks can be constructed out of Rainbow-based storage mediums. Although the main attraction is cheap paper right now, other media can use the Rainbow system too.

As of right now, Abideen's system is still under research at the Muslim Educational Society Engineering College and although no major companies have expressed interest, Abideen is confident of the system's future. According to the report, Aibdeen is hard at work at developing a Rainbow scanner that would be small enough for integration into notebook computers. If developed, a Rainbow printer will likely be next up.

In other high-capacity storage news, DailyTech previously reported that Hitachi-Maxell is in the progress of producing holographic media for shipment this year. Holographic storage is one of the biggest forward-looking storage technologies and holds a great deal of promise -- as well as data.

This sounds like great technology. But the one thing that i find interesting is the fact that it IS printed on paper. Paper isnt exactly a practical storage medium. If colors are to be used to store information then with paper colors would fade over time and lead to data corruptions. Also paper isnt a sturdy medium at all. I didnt get exactly how important the paper was and if this technology could be applied to plastics like a memory card. Also i do not understand why shapes are more effective than binary. Unless 1 shape equates to more than one byte of data. maybe this is where the current develpement is, and why we are not watching high def movies from paper.

Supposing we all converted to paper storage. All we would need is a fire, and we are screwed big time. I realize, of course, that fire can damage other storage mediums. But with those, there is a chance of recovery.

You mean like in centuries gone by, where all knowledge was stored on paper? Seems like we were able to preserve some of it until today. ;)

By the way, you can still recover information from a burned piece of paper - as long as no water was poured over it (which usually happen when you try to put a fire out).

The use of shapes and colors means more symbols allowing you to store more data.

Think of it in terms of a binary digit string vs a hexadecimal string:

a 32-bit binary string is 32 characters long, but the same information in hexadecimal is only 8 characters long.

The problem with more symbols is that it could lead to ambiguity - e.g. an octagon could look like a circle or a hexgon, etc. leaving a lot more room for errors in interpretation.
Binary data has the least ambiguity: it's either there or it 's not

I think the ambiguity issue isn't a big one so long as the scanners and printers use a high enough resolution to scan or print them without confusion.

What concerns me is what happens to the data if the page is folded. That could screw up everything along the fold.

I agree, nothing is as simply and clear cut as binary. As for people complaining that paper can burn and fade. Well, if printed and stored properly im sure it will last as long as for what it has been designated for. As for burning, i dont think CDs will survive a fire.

I dont think this will catch on though as shown by the lack of corporate interest.

Colors yes, shapes no. Shapes are just groups of pixels. A shape that is made of 10 pixels contains no more information then the 10 pixels that compose it. Colors do help though since they allow each pixel to have more information.

Think of it in terms of a binary digit string vs a hexadecimal string:

a 32-bit binary string is 32 characters long, but the same information in hexadecimal is only 8 characters long.

Yes but the characters are now more complex. Encoding the 32 binary characters can be done using just 1 32 bit color pixel, or 32 black/white pixels. Encoding each of the 8 hex characters requires 4 black white pixels. Either way the maximum information capacity is the same.

Paper is just a type of print, this technology is something i read about before and it's bascially about geometry.

The principle of this technique is to store information not in a planer binary map, but in a multi-dimensional space, not just 3D, any kind of dimensional space you can com up with. Shapes and colurs allow such dimensions to exist, but this kind of gemetric storage could reside within platic as well, and even if the print in this case is written on a paper, that is still not representing a depth. The medium could be anything really.

It's always intresting with new stuff, just have to wait and see what happens.

I agree.

This is a novel application to storing data. Whereas bits or even hex are values stored in linear fashion, using a plane (2 dimensional storage) adds spacial data that has no way of being emulated by simple hex.

You can specify in binary the existence of 10 dots by having 1111111111 as your data value, but how do you specify WHERE in the plane of that media (paper in this case) they are, and HOW they are spacially arranged? They can be in a circle, square, triangle...and then how large is the shape? These are parameters that add nearly incalculable permutations of data.

Conventional data is only 1 dimensional--stored in linear array. This is 2 dimensional data. If he were to perfect his compression algorithm , I'd wager good money that 450GB IS MERELY THE BEGINNING.

Feasibility test:
I have just scanned an A4 size image into lossless 24-bit BMP at 300 dpi. It produced a 26 MB file. Doubling the resolution makes it over 100 MB, still far away from the GB range. This invention is flawed at its root:
- I do not see how you could increase the capacity by using shapes like circles and XYgons. Color dots are your best bet.
- you can NOT practically increase capacity by using greater color depth. To reliably retrieve more info stored in color, one would require ALL printers and scanners with unprecedented calibration, e.g. the shade of orange printed on ALL printers MUST be read on ALL scanners as the exact same 24-bit color.
- you can NOT practically increase resolution. Depending on the placement of paper, the info could be read back in different ways, for example.

- on the other hand, you COULD add redundant recovery information, like in RAR, which decreases capacity but increases readability in case of bad media.

All in all, we will either never hear of this "invention" again (as he will not be able to produce working prototypes), or we will, but in a scandal...

Macro-world (like printed stuff) will never reach the "information stored per square inch" ratio of the micro-world (a bunch of electrons in a memory cell).

Assuming you have a REALLY high quality printer that can print at 4800 x 2400 dpi, and you're doing a full bleed print onto 8.5 x 11 paper, there's the potential to have over 1 billion dots on that piece of paper.

Encoding 1 gigabits though, even under ideal situation of a printer that maintains that print resolution, and a scanner that can perfectly read it, you'd need either some sort of laser alignment, or you'd need to have "stop" bits, perhaps only using every other "bit" on the paper so that an encoded "11111" wouldn't just be an indistinguishable line.

Using shapes to represent various bit patterns, like saying that a square would be 1011 and a circle is 1100 and triangle is 0011, etc. would be one way to encode data into unique identifiable patters, but then creating those shapes requires probably at least an 8x8 dot area, so you've just reduced the number of "patterns" per page from 1 billion to 16.8 million (each patters being 64 dots).

If you were able to come up with 16 shapes that could be uniquely identified, without misidentifying problems like mistaking a hexagon for a circle, then you can use each shape to represent a 4 bit number... hooray. However I'm not sure how many unique shapes you can squeeze into an 8x8 matrix before it gets harder to distinguish...

So each pattern can represent 4 bits, putting you at about 64 megabits on the paper.

Using colors, let's say an 8 color mix to start although you wouldn't be able to use white if you're using white paper, you're looking at squeezing another 3 bits into each pattern, for 7 bits total (16 shapes, 8 colors).

That still only gets you about 118 megabits per page of paper.

Now, that's assuming ideal conditions, an unrealistically high printer and scanner accuracy, etc.

The ONLY way you're going to get 450GB per page is if you think you can print in millions of colors accurately enough that a perfectly tuned scanner would read that color back just as accurately, letting you encode each shape and color with far more than the 7 bits I hypothetically mention.

Since 450GB is 3.6 terabits, we're talking about taking those 1 billion dots on the paper and using shapes/colors to squeeze another 3342 times as much info. That's a pretty amazing feat if possible and I don't think this "invention" is anything new...

Someone mentioned a magazine that used to print a bar-code like thing in it's articles that included source code. You could use their special scanner to import that code into your system, saving you all that typing. I think that was PC Magazine or something back in the late 80's or something similar. Cool when it worked, but when the price of CD's/floppies and especially online access came around, the concept wasn't necessary anymore. And you couldn't really encode all that much on a page, but I guess by 1980's standards it may have seemed like a lot.

Exactly. You seem to be the only person here who understands that symbols divide the bit capacity into cunks. They don't increase the capacity. Everybody else seems to think the symbols magically multiply the number of bits. They are making the same mistake as somebody who thinks 32 ounces of gasoline magically turns into 96 ounces when you pour it into the tank, because those ounces can be divided into 4 cups or two pints or one quart, and those units add up to 96 ounces.

The ONLY way you're going to get 450GB per page is if you think you can print in millions of colors accurately enough

But here you're making that same mistake yourself in a different form (with regard to color instead of shape) because the printer is able to print millions of colors only by combining dozens of spots of ink, and the ink comes in far fewer colors. It's the individual spots of ink and the number of colors of ink that determines the bit content. Combining those things into units (in this case, the combined unit is a pixel) doen't add capacity. It merely divides the existing capacity into a chunk.

There's one thing not taken into account with your example, you can also use the relative position of symbols to eachother to expand the data, the same way RAR's compress data, as a simple example if you for instance say 'X' represents 'now follows a sequence' and then the next byte says what byte and the next how many times, then you can represent 256 bytes with just 3 bytes of data like 'XA256' equals 256 A's.
Of course that only works for sequences of similar characters in this example, but that might be the joke here, will this work for uncompressible information?
And even when using compressible information the claim of such sizes seems impossible unless you use a new algorithm that could just as well be used to expand the datacapacity of say DVD's.

If that's the case then it incorrectly presented.
You should always give a media true capacity... that would be like seeling a 600GB HD and when you bought it you'd find out it was really 300GBs and you'd have to activate NTFS compression and use only a selected few types of files in order to achieve 600GBs...
I believe this is not the case or this would be a truely disgusting spin on the researcher's part. Storage technology and compression technology are two different (obviously very related) areas and should not be confused or used to confuse.

If 450gb of data can be stored on a piece of paper and you only need a scanner to read it then a simple picture file could contain all that data too... This could possibly be used as a new compression method. Unless, of course, the resolution needed to read such data is too high resulting in a picture file almost as big as the original data.

I agree stevenplatt, paper isn't a good medium for that much information because the data could be lost so easily : humidity, fire, ink fading with age, even folding the paper could alter the data too.

I think the point of it is just to have a cheap storage medium that anybody can carry around or use at any time.

It's also a technology concept demo. They could use anything to store the data. What's critical is this "rainbow code" thing they talk about.

This isn't an original idea, we all know that hexadecimal can store more data than binary with fewer digits, but its an extension of that idea designed to get this dude his graduate degree of some kind.

I think the main point of this is just that this method allow the use of cheaper medium to store data. Instead of producing those flash memory chips or CD/DVD (including HD and Blu-Ray) discs, it will theoretically allow the use of regular paper or plastic to store your data.

However I think it is just too impractical for too many reasons. First of all the media is just too frail, and as pointed by several people paper can be easily folded, and easily destroyed, as well unless they can invent inks that will not fade over time or peel off the paper, then data integrity is almost impossible to achieve.

Secondly as pointed by another poster, you will need a very very high resolution scanner, and not to mention printer to actually store the data and then retrieve it again. And not to mention how much processing power will this entail. I mean in the end we're still dealing with a binary system, so this technology will just slow down the data processing.

I think at the end of the day, the impracticality, the lack of data security is just way too much to overcome as opposed to the gain in savings on the medium. This I believe will just become a dead end technology that might never see the light of day in the retail market.

Could that much data be stored on one page?

- your print job to print that page must have at least 450GB
- and your scan of that page must have at least 450GB
to contain that information.
This is about storage, so don't throw in compression.

Usually, the print size should be larger because of redundancy for error correction, and you scan should be larger (higher (spatial/color) resolution) to improve correct readout.

Just think of this new technology as a bigger DVD-R drive. The drive doesn't have 8+ GB of internal storage, the data is transfered (from DVD to HDD or RAM when reading, from HDD or RAM to DVD when writing).

About the print size: instead of increasing it, you reduce the amount of data available to the end user, just as a DVD holds a lot more than 8+GB of data, but uses some of it for error correction and leaves you with about 8GB.

Not all Muslims are terrorists nor are all terrorists Muslim. This sort of random stereotyping is highly insulting and will not benefit anyone.

I do however, agree that combineing reglion and science is a terrible idea and that his claims of capacity seem far fetched. Say the standard has 10 shapes and 6 colours (60 combinations). If we are using an 8.5 X 11 sheet of paper we have a total of 93.5 inchs square to work with (assuming no margins at all). 450GB (3865470566400 bits) assuming 60 combinations is still 64424509440 unique shapes that will have to occupy that page. or about 689032187 per square inch. My current inkjet printer has a maximum resolution of 4800x1200 or about 5760000 dots per inch. Now each shape would need to be composed of at least 9 dots (probably more), probably much more. This means you would need a printer that is about 1076 times as accurate as this (I haven't even gotten to ink bleed or scanning this in accurately afterwards).

I don't see any way this could be feasible as a replacement for optical or magnetic storage, the density of symbols required to compete would be too high to accomplish at a lower expense than just using a DVD or hard disk.

This might be useful in developing countries where more complex storage systems are not avaialable or too expensive but these claims of storage capacity are just too overinflated.

This is one of those "silent thunderclap" technologies people never pay much attention to until it is in full use somewhere. This particular approach may never see widespread use, as there have been numerous attempts to encode data in similar means. So the idea is more evolutionary than revolutionary. If you really want to evaluate this technology simply remove the term paper and replace it with "two dimensional optical media".

The compression analogy is a good one. The bulk of the idea is to separate data density from what it has, throughout the history of modern computing, been inexorably tied to: The physical capacity of the storage medium.

They already used a pattern printed on ID cards that decode to the picture on the ID's, to prevent manipulation or falsification, by scanning the pattern a computer display shows the picture and if it's different from the normal one on the ID you know it's fake.

I (and many others) do believe it is theoretically possible to uniquely represent enormous amounts of data with a small value and then using the right algorithm retrieve that data back.
For a while they thought MD5's were always unique (and with enormous effort it is reversible) but then mathematicians proved it wasn't 100% foolproof and theoretically two dissimilar sets of data can have the same MD5, still, there must be an algorithm that makes it possible, problem is finding it and then making it reversible with current computing powers.

Everyone believes this. What you're talking about was proven by Shannon in the 1940s, before there were even computers. He used books in a library which he opened to random pages. Seriously, what you're talking about has been a huge area of research for 50 years now. Wikipedia him and start reading his papers.

For a while they thought MD5's were always unique (and with enormous effort it is reversible) but then mathematicians proved it wasn't 100% foolproof and theoretically two dissimilar sets of data can have the same MD5,

No one ever thought MD5 was unique. By definition MD5 was not unique. They thought there was no computationally reasonable way to calculate one of the infinately many possible files that would have a given MD5 sum.

still, there must be an algorithm that makes it possible, problem is finding it and then making it reversible with current computing powers.

What, reverseing a hash? Theres a universal algorythm for that. Just compute the has of all possible files and see which ones match.

This appears to be an entirely new way of looking at storage media and algorithms, and there is simply no way to guess where it might lead. I think it is myopic to immediately categorize it as a replacement for anything. If you just sit down and give a thought to ways in which the current storage technoloigy are deficient, I think you can make some guesses as to how this new tech might me used. Immediately I came up with one: paper vs extremely complex and exotic hard drive platters as the storage medium. Cost? Availability?

Is there anyone else out there who can see beyond their noses?

Ok, whether or not the report is accurate, why is this considered interesting storage news? It's not because of the speed, ability to rewrite, or durability. It must be because claims were made that VERY large amounts of data could be stored on a single sheet of paper.

Ok, so what makes it able to hold 'so much'? I think it's because each piece of info can hold more than just 2 values, unlike current storage, which holds zeros or ones (bits). So, can't we cram something onto a platter that has more than 2 possible states? Why do we have to make a quantum leap backwards to visually representing data on paper?

I believe that's why there is such skepticism going on here.

2 pixels, each 4 bytes, or 64 bits of information total, can represent
1.84467441×10^19 possible values. thats way more than this 17179869184 number you come with (from where?), and it's still just 8 bytes. it's not 16GB or anything. get a grip.

try to figure out the difference between number of possible values and number of bits. 256 possible values are still just 8 bits, and 1.84467441×10^19 possible values are still just 64 bits of information, no matter how huge a number it may sound. your 17179869184 possible values are only 34 bits, not 16GB.

Sure, this is the start of a great idea. Think of it, companies being able to trasfer data in mass storage on a piece of paper. But the problem is that paper is not very reliable for storage considering how fragile it is.

I think it would be more reasonable if a program was created that allowed data to be converted to his type code and then put on a CD or DVD. Then once data is transfered it can be convereted back to its original type of data.

This is the same idea of compressing files but in a more effective manner.

Also the code he is using is the same idea of quantaum computers except a quantaum proccessor use numbers like 1,2,3,4,5,6 to convert data instead of colors and shapes.

Now, circle in a square with six colors give 6 new bytes for one color if both same color, so 2^6 combination of colors and 6x that. so 384 new bytes right there. now that is just two shapes...if three shapes involved then 3^6 just for colors not mentioning orientation of objects... for instance circle in squre in triangle or triange in circe in square...get my drift....i think ai software algorithms would fit nicely in this type of software compression

Oil on the other hand is not renewable in the way we use it today. Oil is what is used to make CD/DVD so they are much more harmful to the environment then paper.

If you read the article you would also learn that this tech doesn’t involve paper per se. Its printing that is required. But you can print on many materials like plastic, metal etc if you think its better.

Let's assume they were talking about an 11x17 sheet of paper. Let's further assume that they can deposit pixels at 2000 dpi. That gives 748 million pixels assuming 100% coverage. Now, lets assume that they can deposit color with 12-bit accuracy and read at the same accuracy - that's 12 bits per color, for 48-bit color, which is about the limit of possibility with real equipment (that is to say, each independant color can be measured to a signal to noise ratio of 4096 to 1, or 72 dB). That gives 36 bits of information per pixel, 12 each from R, G, and B. 748 million pixels times 36 bits = ~ 27 gigabits, or 3.3ish GB.

PrinceGaz, your calculations are incorrect. The amount of data any amount of bits can hold is 2^n. For example, with two bits, you can have 4 different combinations of data (i.e. 00, 01, 10, 11) and 2^2 = 4. Your 2 x 10^n formula predicts 200 different pieces of information for two bits, which is wrong as there are only four different ways that you can utilize two bits.

Can you find any other combinations that two bits can form other than 00, 01, 10 and 11? If you cannot, then it stands to reason that the formula for a base-19 encoding scheme would be 19^n.

In fact I fail to see how storing the information as coloured shapes could possibly have a higher data-density than simply using coloured dots...

You're right, it doesn't. The data capacity is the number of bits. The fact that the bits can be viewed in different ways (as composing symbols) is irrelevant.

Think of it this way. Eight bits can be permuted in 256 ways. That's why a byte (which is made of 8 bits) has 256 possible values.

Now we can think of a byte as a hex number. Or we can think of a byte as a color. Or we can think of a byte as a code for "circle", "square", "triangle", etc. But no matter how we think of that byte, it still contains only 8 bits, and it still can encode only 256 possibilities.

This logic has one flaw - mechanically, you can't print on the edge of the paper where you hold the most data. Also, printers don't print single shades of colors, they print in single color dots that "look" like a shade of colors if they are gapped on white paper. This means that you have to calculate the color for a larger region of paper, lowering your data density. Perhaps paper or laser printing will never be the solution to data storage.

If you were to have 1 cm^2 blocks on a piece of paper, with each one either being there or not, each one would represent a bit. Now, imagine the same encoding scheme, except with different colors and shapes either being there or not being there.

With this scheme, you can theoretically store an infinitely greater amount of information in the same area that you would have a single bit, but as the data density rises, reading it becomes more and more complex, and eventually, it becomes absurdly difficult to discern between one symbol and another, especially as the wavelengths of each color rises and the number of sides on the polygons increase. However, it is possible. The Chinese have hundreds of thousands of different characters and they are able to read them without much a problem, although learning to use them is extremely difficult.

If this scheme is adopted for data storage, it will only be used for short term read-only data storage, as the colors will fade with time and it is impossible to rewrite to such a medium.

Lets say you are storing 95 full 4.7 gig movie DVDs. I can only imagine that it is impossible to find a pattern to which you can create a logarithm to compress 450 gigs on a single piece of paper. Sure this is taking into account that the shapes will also be colored, but DVD movies are also in color. To say that you can store 450 gigs worth of...say movies... on a piece of paper...

I'm just saying 450gigs on a regular sheet of paper is BS. Maby somewhere along the lines of 10-40 gigs more like it. For 450 gigs to happen, it will be a special factory made "paper size" material that wont be made of paper. In the future of course. Even then, you can only compress an image file so much.

What if it was 450 gigs worth of JPEG files? To say that you are going to use shapes/colors to replicate the image in a digital format on a piece of paper....hell you mind as well just print the image out.

Whilst I agree that the 450GB aspect is nonsense right now, and even 1GB seems preposterous (and why use large 'shapes' instead of small shapes for binary representation?), I take issue with your claim that printing the image would be better, especially in the case of video.

JPEG and digital video (e.g., H264) are heavily compressed to fractions of their decompressed size.

How much? Lets take a 720P 10mbps video stream. A single frame (1280x720, 24-bit colour) takes up 2700KB of data. A second (60fps) is therefore 158MB of data, or 1266mbps. Yet the stream is 10mbps! The compressed file is under 1% the size of the decompressed file.

Quite clearly storing the compressed file is better than printing out the images from each frame of the video, even if the encoding used is bulkier.

Two mistakes keep cropping up in this thread. First, the fact that dots are combined into symbols has nothing to do with the amount of information that can be encoded. Second, this "invention" has nothing to do with compression. It has to do with storage capacity. (One way of thinking about the second issue is to assume the data was previously compressed as much as possible.)

As with all digital data, the amount that can be stored by this technology can be measured in bits. This is independent of whether the bits are arranged in symbols or hex numbers or anything else. In this case the maximum number of bits is the number of dots that can be both printed AND read accurately by the scanner, multiplied by the number of possible colors for each dot, minus some factor that has to be reserved for error correction.

To estimate the maximum amount of data that could be encoded, let's assume (very liberally) that the maximum number of dots per inch that can be printed AND read accurately by the scanner is 4000 dots per inch. (This is an extremely generous estimate because even though scanners can measure 4000 points per inch, the points won't usually line up with the dots). And let's assume that the printer can print a dot in 6 possible colors (including white as a color). And let's assume that the printed area is 8 " x 10.5". Then the maximum number of bits on the page (aside from error correction) is:

16 mllion bits per square inch x 84 square inches x 6 colors = 8.065 billion bits = 1 billion bytes

So the maximum data capacity, even before we subtract a chunk for error correction, is less than one gigabyte.

But in fact the real capacity would be less because the scanner won't be in alignment with the dots. Think of a the read/write head of a hard disk. It prints exactly like a printer, except that the dots have only two colors (magnetized and de-magnetized). And it reads dots just like the scanner. Except the hard disk has a single read/write head that is designed to stay in alignment with the dots on the disk. The scanner will not be in alignment with the dots on the page. Therefore the actual density of dots that can be successfuly read by the scanner will be lower than what I just assumed in the calculation.

Yeah they would have to make a bigger dot to guarantee that the scanner would be able to read every bit of information correctly, and this is assuming that once you get to the size that is required to get 450Gb you would probably start having problems with distortion of the paper, since it obviously will start getting bumpy or porous zoomed in that much. and I would assume that touching the paper in any way would probably ruin the information with the oils on your skin. I would assume that there would be better ways of storing information then on paper

The math is fine.

First, notice he said you needed a scanner. He also says he'd need to develop a rainbow printer as well, you can't just use off the shelf $80 ink jets. The article, if you read it... He stored a 45-second video clip... And in the FUTURE, using the tech you may be able to store between 90 and 450GB of data.

Given a standard piece of paper (Of which the article doesn't even say it's that small), but let's just start with that. Today's scanners can do 48+ bit color scanning, and over 4000dpi.

8.5*11*48*4000*4000=71,808,000,000 bits of information. Or almost 9GB. Toss in some compression (ZIP-type lossless) which CAN compress some data to 1% of it's original size, and you have a theoretical data storage capacity of 900GB on a page. Add some error correction, and some fancy way of allowing the system to detect minor skews, and it's possible to store 450GB of data on a piece of paper TODAY.

Of course that 1:100 compression ration with ZIP-type compression isn't common, but that's not what the article said. In fact the guy didn't even claim he could do 450GB today. He said he did a 45-second video clip. I can store a 45-second video clip in my phone, and it'll take all of about 100k. It looks like total crap, but it is 45-second of video.

Not really BS, just not very useful.

What you are missing is that those "48+ bit" scanners are DIGITIZING to 48 bits, but do not in fact have 48 bits of meaningful information. The signal to noise ratio of those scanners is typically around 512 to 1 (or 8 bits per color for true 32 bit color) for a good unit.
