Face recognition appears as the most successful biometric application used. However, controversy also revolves around security solutions. There is an incidence of biometric face detection system, can’t identify the correct face. Device failure that is not too often to carry out the debate. Technology reliability is being questioned. Many organizations protest the use of this technology as a defense tool. But, face recognition is a trustworthy security measure!
Biometric face detection system works to measure facial features that cannot be changed. Distance between two eyes, lip thickness, cheekbones and other facial characteristics remain constant throughout life. This technology involves registration of certain faces into the database, based on facial algorithms. Next time, the same face appears before the system, is recognized after compared to other faces in the database. Modern face recognition software uses 3D images for higher accuracy.
Nothing is perfect in the world. Complete protection no! Just like the others, this machine is susceptible to errors. Biometric face detection system can fail in two ways; Whether it identifies a foreign face as a genuine (false positive) or denies the identification of the original face (false negative). Accurate face recognition can be affected by lighting conditions, facial expressions and further external factors. The possibility of false negative and false positives cannot be ruled out.
However, this application can be considered competitive than conventional security solutions. Professor of computer science and technology believes that it ensures majority security. A long proverb in security circles, “There is no such thing as a 100 percent shield”, justifying the argument. Biometric face detection system can inhibit the unwanted elements most of the time. The manufacturer claims that this mechanism is nine times accurate from ten. It is new technology. There is a lot of scope for repairs in the coming years.
Face detection is in demand! Casinos can use biometric face detection systems to control cheating, individuals with debt, criminals, and troublesome players. Schools can arrange machines using this mechanism for attendance and access control. Face recognition can also be used in hospitals, offices, government places that are very safe. The modeling is increasing at the airport. Being an easy target for terrorists, airport authorities around the world using this biometric security device to improve security. Despite the opposition from the civil liberties, the acceptance increased.
The computerized mechanism has many successful stories for their credit. This system leads to around 500 arrests and almost as many positive identification that does not lead to catching in Pinella, US. Biometric face detection system has become part of a daily work in the police department. Police can identify teachers of football hooligans in the crowd at West Ham Games with the help of this software. Government officials believe that the September 11 attacks can be prevented, if the biometric face detection system is used at the airport.
