New Sophos facial recognition technology uses webcams to stop hackers
and virus writers in their tracks
----
Today, April 1, Sophos announced its new RAPIL (Recognition and
Analysis of Potentially Intruding Lifeforms) system which is able to
produce a real-time forensic analysis of facial features using
webcams, to assess the facial characteristics of computer users, and
cross-references them against features typically found in
cybercriminals. The ability to stop hackers before they even get a
chance to write their malware, let alone spread it, is a breakthrough
in the fight against cybercrime. Keep reading for more on the RAPIL
beta and how you can help the fight against malware.
