Using a graphics tablet, a human would pinpoint facial features coordinates, such as the pupil centers, the inside and outside corners of eyes, and the widows peak in the hairline. Their early facial recognition project was dubbed "man-machine" because a human first needed to establish the coordinates of facial features in a photograph before they could be used by a computer for recognition. History of facial recognition technology Īutomated facial recognition was pioneered in the 1960s by Woody Bledsoe, Helen Chan Wolf, and Charles Bisson, whose work focused on teaching computers to recognize human faces. The change represented one of the largest shifts in facial recognition usage in the technology's history. Growing societal concerns led social networking company Meta Platforms to shut down its Facebook facial recognition system in 2021, deleting the face scan data of more than one billion users. These claims have led to the ban of facial recognition systems in several cities in the United States.
The appearance of synthetic media such as deepfakes has also raised concerns about its security. The use of facial recognition systems has also raised controversy, with claims that the systems violate citizens' privacy, commonly make incorrect identifications, encourage gender norms and racial profiling, and do not protect important biometric data.
Their effectiveness varies, and some systems have previously been scrapped because of their ineffectiveness. įacial recognition systems are employed throughout the world today by governments and private companies. Facial recognition systems have been deployed in advanced human–computer interaction, video surveillance and automatic indexing of images.
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. Because computerized facial recognition involves the measurement of a human's physiological characteristics, facial recognition systems are categorized as biometrics. Since their inception, facial recognition systems have seen wider uses in recent times on smartphones and in other forms of technology, such as robotics. ĭevelopment began on similar systems in the 1960s, beginning as a form of computer application. Such a system is typically employed to authenticate users through ID verification services, and works by pinpointing and measuring facial features from a given image.
