How Does Facial Recognition Work? Know The 4-Step Process!

facial recognition system India


Biometric security includes facial recognition as one of its subcategories. In addition, voice recognition, fingerprint recognition, and retina or iris identification are all examples of biometric software. Currently, the technology is primarily used in security and law enforcement, although interest in other applications is growing rapidly.

How Does It Work?


Face ID, which is used to unlock iPhones, is a famous example of face recognition technology (however, this is only one application of face recognition). It's not uncommon for facial recognition systems to identify a person as the sole owner of the device while restricting access to others.


Besides unlocking phones, facial recognition compares people's faces to photographs on a watch list. There is no limit to the number of persons who may be added to the watch lists, and the images can come from any source, even our social media accounts. As a general rule, facial recognition system India work like this:


Step-1 - Identification


In a crowd or by itself, the camera recognises and pinpoints the image of a face. The subject in the picture may be seen either staring directly ahead or in profile.


Step-2 - Analysis


The face is then photographed and examined. Because it is easier to match a 2D image with publicly available photos or those in a database, most facial recognition technology uses 2D rather than 3D images. The software reads your face's geometry. The separation of your eyes, the depth of your eye sockets, the space between your forehead and chin, the form of your cheekbones, and the shape of your lips, ears, and chin are all essential. Finding the facial features that make your face distinctive is the goal.


Step-3 - Conversion To Data


The technique converts an analogue piece of information—a face—into a collection of digital bits of information—or data—based on the subject's facial traits. In essence, a mathematical formula is created by examining your face. A faceprint is a name given to the numeric code. Each person has a distinct faceprint, similar to how thumbprints are unique.


Step-4 - Matching It Up


A database of other known faces is used to compare your faceprint. Any photo tagged with a name on Facebook is added to Facebook's database, which can be used for facial recognition. A decision is made if your faceprint matches a photo in a facial recognition database.


Facial recognition is regarded as the most natural biometric assessment of all. This makes intuitive sense given that we often recognise ourselves and other people by looking at their faces rather than their thumbprints or irises. Over half of the world's population regularly interacts with facial recognition technology.
