A facial recognition system is a technology capable of matching a human face from a digital image or a video frame against a database of faces, typically employed to authenticate users through ID verification services , works by pinpointing and measuring facial features from a given image. While initially a form of computer application , facial recognition systems have seen wider uses in recent times on smartphones and in other forms of technology, such as robotics. Because computerized facial recognition involves the measurement of a human's physiological characteristics facial recognition systems are categorised as biometrics. Although the accuracy of facial recognition systems as a biometric technology is lower than iris recognition and fingerprint recognition , it is widely adopted due to its contactless process. Automated facial recognition was pioneered in the s. Their early facial recognition project was dubbed "man-machine" because the coordinates of the facial features in a photograph had to be established by a human before they could be used by the computer for recognition.

Facial recognition—the software that maps, analyzes, and then confirms the identity of a face in a photograph or video—is one of the most powerful surveillance tools ever made. Concerns about that ubiquity, amplified by evidence of racial profiling and protester identification , have caused major companies, including Amazon, IBM, and Microsoft, to put a moratorium on selling their software to law enforcement. Every facial recognition system works differently—often built on proprietary algorithms—but you can sort out the process into three basic types of technology:. The detection phase of facial recognition starts with an algorithm that learns what a face is. If you cram in enough pictures to train the algorithm, over time it learns the difference between, say, a wall outlet and a face. The diversity of photos fed into the system has a profound effect on its accuracy during the analysis and recognition steps.
