FACIAL recognition is a technology capable of recognizing a person based on his face. In simple terms, a facial recognition algorithm works in the following WAYS:

• The facial detection system takes photos as input.
• The system reads your facial features. Facial features used by different systems can differ. Some facial features used by these systems to distinguish a face are- the distance between the eyes, the length of the forehead, the contour of the eye socket, the shape of nose and chin, the position of any mole, etc.
• The algorithm verifies your face. It encodes your face into a signature (a vector of information in the form of numbers). These numeric codes are also called faceprints which are analogous to Fingerprint in contact biometric systems. Each code distinguishes the individual from the rest of the training dataset. During the face detection procedure, the feature vector is then utilized to look across the whole DATABASE of enrolled people. The system then compares the signature with the database of stored images, looking for a potential match. The database contains all the information on the users who have signed up. If the software finds a match for an exact feature in the database, it displays all the information about the person.
• If any match is found, the system takes further action. For example, it can grant access to the system if the user is registered.
