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. This has led to the rise of several facial recognition companies in India. The face is mapped out in detail during this process so that an incorrect match or false denial is minimized.
How does it establish an identity?
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.
Eliminates human errors
A large advantage to face recognition software is that it eliminates human error to a large degree. Someone can try and talk a security guard into allowing access, or reproduce an access card as it provides emotion recognition solutions. However, for obvious reasons, it would be difficult to duplicate someone else’s facial features. Even identical twins have subtle differences that are picked up by the software. These subtle differences are what make the software hard to trick or fool. When you consider the many nuances of someone’s face, including their expressions, it becomes obvious why this would be so difficult to get past a facial recognition access control system.
Facial recognition software is a bit more expensive upfront but can offer savings over the long term. There’s no need to maintain and replace access cards. Access cards can be lost or stolen which requires more administrative maintenance as well as the additional cost of replacing the cards. Without having to have someone to maintain the cards, or pay for new ones, it soon becomes evident that excess cost is being eliminated. Additionally, access will never fall into the wrong hands by theft or loss. When an employee leaves their employment, keys and access badges are not always turned in.
