Face Recognition Technology

Face RecognitionTechnology is the least intrusive and fastest Biometric technology. It works with the most obvious individual identifier – the human face. Facial Recognition analyzes the characteristics of a person's face images input through a digital video camera. It measures the overall facial structure, including distances between eyes, nose, mouth, and jaw edges. These measurements are retained in a database and used as a comparison when a user stands before the camera. This Biometric has been widely, and perhaps wildly, touted as a fantastic system for recognizing potential threats (whether terrorist, scam artist, or known criminal) but so far has not seen wide acceptance in high-level usage. It is projected that Biometric facial recognition technology will soon overtake fingerprint Biometrics as the most popular form of user authentication.

How it Works?

The following four-stage process illustrates the way Facial Recognition systems operate:          
·         Capture - a face sample is captured by the system during enrollment.
·         Extraction - unique data is extracted from the sample and a template is created.
·         Comparison - the template is then compared with a new sample.
·         Matching - the system then decides if the features extracted from the new sample are matching or not.

When the user faces the camera, standing about two feet from it, the system will locate the user's face and perform matches against the claimed identity or the facial database. It is possible that the user may need to move and reattempt the verification based on his facial position. The system usually comes to a decision in less than 5 seconds.
