Here’s a really interesting face scanner security for your PC. I don’t know how their secure the software is but the face recognition technology looks pretty valid.
XID Technologies has recently made a new option available for protecting your own computer: a biometric PC access application called Face LogOn Xpress. In plain English, that’s a face scan. Now, instead of limiting your PC security to a password (or a fingerprint scan, for some devices), you can install a program that scans your face in order to provide security clearance for logging on to your computer. This can be used for home or work computers.
