Caller
ID spoofing has been a popular practice for many years in the U.S.
Many have a form of caller identification and use it to screen their
calls. Much like email spoofing, caller ID spoofing causes the
message to look like it originated from someone other than the real
sender.
Many businesses offer spoofing service either online
or via the phone. Among the legitimate uses of spoofing are to
allow businesses IDs to appear when owners are making calls from
outside phones (such as a home phone) and to allow businesses to
replace the calling number with the appropriate callback number.
Private investigators and collections agencies often use spoof as
well, in a more questionable manner.
Spoofing has also been
used by criminals to steal money from victims by tricking them into
revealing personal information. Last year a ring of crooks
stole $15M USD using phone spoofing according
to Representative Eliot Engel (D-NY).
After much
debate, the House has passed the bill Truth
in Caller ID Act of 2010" [PDF], H.R. 1258, an amendment to
the Communications Bill of 1934. The bill effectively bans
caller spoofing in the U.S. The Senate already passed a similar
bill in February, so President Obama should soon sign the Act into
law.
The bill makes it illegal "to cause any caller ID
service to transmit misleading or inaccurate caller ID information,
with the intent to defraud and deceive."
It applies to
both land lines and voice-over-IP networks (VoIP) and any other "real
time voice communications service, regardless of the technology or
network utilized."
Under the bill, you can still block
your own outgoing caller ID information. But trying to modify
it may result in criminal and civil penalties, assuming it can be proven that you intended to "defraud and deceive". Businesses may be exempt, assuming they're using spoofing for legitimate purposes as outlined above and not suspect practices like stealth telemarketing.
Civil prosecution generally carries a lower burden of proof, so businesses such as repossession firms may be hit with civil fine but escape criminal prosecution.
Law enforcement
officials in the U.S. are exempt from the ban.
CTIA, an
international trade group, released a statement praising the move.
It writes, "CTIA and the wireless industry support making caller
identification spoofing illegal as the applications of such an
activity are usually for malicious purposes. We appreciate the House
passing this important consumer protection measure."
