What Is Facial Recognition Software?
Facial recognition software used to be fodder for sci-fi and futuristic type movies. No one thought that while watching these shows that the technology demonstrated within would be a reality in the not too distant future. However, its time has come with more mainstream businesses implementing this technology with its heightened security. Face recognition access control systems are the next step up in higher security.
What is face recognition? Face recognition software works by creating a digital representation of a person’s facial image. It does this by closely analyzing the structure of the face using features such as nose, cheekbones, lips, and eyes. Essentially it builds a detailed map of the angles, lines and features of the face and then converts it to a file containing all of the information that was gathered during the verification process where the face was associated with the person being added for access. The face is mapped out in detail during this process so that an incorrect match or false denial is minimized.
Facial identification uses one of two methods to establish identity. The first is geometric where distinguishable characters are compared. The second, which is photometric, uses an analytical way of converting the features of the face to a numeric value. This value is then compared to the templates stored within a database. The identity of a person is first established when they are entered into the system. Pictures are taken from several different angles to establish a clear map of the features of the face. This is then entered into the system. When the person then requests access, the system will compare the value it sees with the values that it knows are allowed to have access.
