Facial recognition software used to be grub for sci-fi and futuristic sort movies. No one idea that while watching these shows that the technology demonstrated within would be a reality in the not too distant future. However, its opportunity has arrived with more mainstream businesses implementing this technology with its uplifted security. Face recognition access control systems are the following stage 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 document containing all of the information that was gathered fire alarm system 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 mathematical 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 gone into the system. Pictures are taken from several different angles to establish a clear map of the features of the face. This is then gone 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.
A large advantage to face recognition software is that it eliminates human error to a large degree. Someone can attempt to talk a security guard into allowing access, or imitate an access card. However, for obvious reasons, it would be difficult to duplicate someone else’s facial features. Indeed, even identical twins have subtle differences that are gotten by the software. These subtle differences are what make the software hard to deceive or trick. When you consider the many nuances of someone’s face, including their expressions, it becomes obvious why this would be so difficult to move beyond a facial recognition access control system.
Facial recognition software is a bit more expensive front and center but can offer savings over the long term. There’s no compelling reason 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 clear that excess cost is being eliminated. Additionally, access won’t ever fall into the wrong hands by theft or loss. When a worker leaves their business, keys and access badges are not always turned in. Using a person’s face to gain access means that business owners won’t ever worry about where their access badge or keys wound up. This provides a lot easier way for a business to maintain security.
