Introduction 

According to Lin (2000), Facial Recognition Technology (FRT) is one of the few

biometric systems that help identify an individual based on their biological characteristics. Researchers from diverse fields including security, computer vision, image processing, and psychology have gained a deep interest in the technology, owing to its high accuracy and low intrusiveness. FRT works by identifying and verifying an individual’s still image or video of a scene and confirming it with one stored in a database. This paper aims at investigating the basic functioning of FRT, areas of applications, and challenges in FRT.

Bobde and Deshmukh (2014) explain that the authentication procedure takes place in four stages; capture, extraction, comparison, and the match. During enrollment, identification, or verification, the system captures a physical or behavioral sample. Next, there is the creation of a template from data extracted from the sample. Unique data is then compared with this new template, and finally, the system decides whether there is a match or not. The algorithms for the framework is also composed of several modules; first, a face image detector identifies locations of the face from a complex background, then the face recognizer determines who the individual is. Both modules utilize the feature extractor which converts the pixel representations to vector representations, which can derive useful information through pattern recognizers (Lin, 2000). The latter searches for the best match for the input image in the database to help identify the

individual in question.
