Facial Recognition Technology (FRT)- when employed as a surveillance technology requires no involvement from the person that is being surveyed or incidentally captured by camera. Unlike other biometrics FRT can operate anonymously in the background. People do not need to surrender their face image as they would their fingerprint or their iris scan. A face can be captured and (de)coded without the person’s consent or active participation. FRT is therefore considered to be a ‘silent technology’.
