Corporation has announced the development of a new technology
for the prevention of SPam over Internet Telephony (SPIT),
called VoIP SEAL, a trade mark protected product.
new technology, which defends against the threat of rapidly
increasing spam IP phone calls, is expected to contribute
significantly to the realization of safe voice over internet
protocol (VoIP) phone networks in the future. The product
will be unveiled by NEC at the 3GSM world congress 2007,
in Barcelona, Spain from 12 to 15 February.
main features of VoIP SEAL are:
arising from spam-generating-software and calls from real
individuals are separated by a Turing test. Before connecting
the call, VoIP SEAL detects and blocks the unauthorised
access, based on the communication pattern observed during
a call. This enables the detection and blocking of SPIT.
adopting a module structure, the product enables a rapid
response to new kinds of SPIT attacks, without adjusting
the system, by adding and updating modules to respond
to new and different kinds of SPIT.
The adoption of a module structure also realises response
to a broad range of applications by enabling flexible
and easy customisation of systems to meet the needs of
a variety of hardware, such as SIP servers, SBC (note
2), home network equipment and terminal equipment.
to NEC, which carried out a SPIT attack simulation project
employing VoIP SEAL to verify the technology''s ability
to protect against SPIT, succeeded in detecting, blocking,
preventing users from receiving unwanted and bothersome
recent years, the spread of low-cost IP phones has advanced
significantly in comparison to fixed-line phones as a
new method of communication in the next-generation network
although IP phones offer cost advantages, they also act
as an easy platform for generating spam calls. The cost
of generating a spam call over the internet is cheaper
than in a traditional network by a factor of 1000. As
a result, the existing infrastructure for producing spam
e-mails (so called "botnets") can easily be
modified to also produce spam telephone calls.
Today, the number of spam emails is higher than the number
of regular emails produced jointly by all of the users
in the internet. If unsolicited marketing and spam calls
become as frequent as spam email, constantly-ringing VoIP
phones may hinder the spread of their use.
