Biometric Face Detection System – Face Detection Is A Reliable Technology

Face detection is emerging as the most successful biometric application in use. However, controversies also revolve around the security solution. There have been incidents of biometric face detection systems, not been able to identify correct faces. Not-so-often failures of the device to perform gave rise to debates. Reliability of the technology is under question. Many organizations protest against the use of face detection as a means of defense. But, facial recognition is a trustworthy safety measure!

A biometric face detection system works on measuring the unchangeable features of the face. The distance between the two eyes, the thickness of lips, shape of the cheek bone and other facial characteristics remain constant throughout life. Face detection involves enrollment of a specific face into the database, based on the algorithm of the face. Next time, the same face appears before the system, it is recognized after comparison with other faces in the database. Modern facial recognition software employ 3D image for higher accuracy.

There is nothing perfect in the world. Complete protection does not exist! Just like everything else, a face detection machine is prone to errors. A biometric face detection system can fail in two ways; either it identifies unfamiliar faces as genuine (false positives) or it denies identification of genuine faces (false negatives). Accurate face detection may be affected with lighting conditions, expressions on the face and further external factors. Possibility of false negatives and false positives cannot be ruled out.

Still, this application can be considered competitive than the conventional security solutions. Professors of computer science and technology believe that face detection ensures security to a large extent. An old saying in security circles, "There is no such thing as a 100 percent shield", justifies the argument. A biometric face detection system can hinder undesirable elements most of the time. Manufacturers claim that this mechanism is nine times accurate out of ten. Face detection is yet a new technology. There is a lot of scope for its improvement in coming years.

Face detection is in demand! Casinos may use a biometric face detection system to control cheaters, individuals with debt, criminals and troublesome players. Schools may set up a face detection machine for attendance and access control. Face detection may also be used in hospitals, offices, highly-secured government premises. Its utilization is increasing in airports. Being easy target for terrorists, airport authorities all over the world are resorting to this biometric security device for enhanced security. Despite opposition from civil liberties group, its acceptance is rising.

Computerized face detection has many success stories to its credit. Face detection system lead to around 500 arrests and nearly as much positive identification that didn't result in arrests in Pinella, USA. Biometric face detection system has become a part of everyday work in the police department. Cops were able to identify football hooligan ringleaders in crowds at West Ham games with the help of face detection software. Government officials believe that the September 11 attacks could have been prevented, if biometric face detection system were used in airports.
