Getting beneath the surface on biometrics

New 3-D techniques are providing better definition of facial features, such as nose and chin, and relax some of the current physical constraints, such as lighting and viewing angle. Another technique, skin texture analysis, also promises performance enhancements.

The game changer on our doorstep, though, may be Facebook. Their recently implemented facial recognition technology enables you to group similar faces together and automatically suggests “friends” for tagging. Your photo is tagged by your “friends,” without your prior approval, and it is up to you to opt out of this service.

Google, Microsoft, Apple and Sony all have introduced facial recognition as features in some of their products. No doubt, this will stir controversy as the public catches on, but it will also drive increasing use of the technology and likely new applications

As biometric technologies continue to improve in accuracy, application and cost, expect them to continue to enter the main stream of public use.
