Review - Real User PassFace
Real User's Passface™ system is a cognometric method of personal authentication - based on the measurement of an innate cognitive function (of the human brain), specifically: its ability to recognize familiar faces. As with passwords and PINs (knowledge-factor authenticators), with Passfaces™ there is a shared secret between the user and the system. However, instead of relying on users to memorize and recall strings of characters and/or numbers, it employs (photographs of) faces as its "alphabet" and requires only familiarization and recognition on the part of the user.
Pros:
· Purely software based and no hardware is required
· Extremely low cost
Cons:
· Although used by US Congress, it is not a major industry standard
· It is a wrapper/hash on top of password authentication, not two factor
Overall Rating:
6 out of 10
