Explained: How Does Online Face Recognition Work & Is It Secure?

Almost one billion individuals around the world currently use Apple’s Face ID to unlock their phones. The use of the same technology to get entry to facilities is becoming increasingly widespread. In this article, we discuss some of the top face recognition authorization solutions that are currently available. These many technologies all have the capability of unlocking doors and other access to structures. 

What does “facial recognition” mean?

There are an almost infinite number of uses for facial recognition software in the consumer sectors, as well as in the tracking and monitoring businesses.

The task of matching an input face to a database containing various face identities is what constitutes the facial recognition process. This activity is frequently utilized in the operation of surveillance and protection technologies. The use of facial recognition technology in law enforcement is a great example. There’s a segment on the INTERPOL website devoted to forensics, and inside that area, you will find an explanation of how face recognition is used to identify people of interest at airports as well as border crossings. You can read more about it in detail here with an expert explanation. 

How does online face recognition work?

Now that we have this information, we can work out how to perform facial recognition. Python is the programming language that is often used to carry it out because this method is thought to be the quickest. The following five primary processes make up the procedure of online face recognition when utilizing approaches based on machine learning:

  1. Examining the Face
  2. Positioning of the face
  3. Face measurement & Extraction
  4. The Image Will Be Converted
  5. Verification

When compared to other kinds of biometric recognition, face detection is regarded as the most native shape of matching. This is due to the fact that trying to compare one person’s facial characteristics to those of another person is the way in which humans could indeed actually decide how one person is distinct from another. The user experience provided by Face Recognition is superior to that provided by other types of biometric authentication methods. It is necessary for a particular portion of the human body to be scanned in order for a specialized sensor to be able to identify a person’s fingerprints, hand palms, or iris. A straightforward selfie taken by the user is required in order to effectively use online face recognition.

Effective and efficient security

A verification method that relies on facial recognition is both speedy and effective. In comparison to other forms of biometric identification, such as fingerprint or retinal scans, this method is far quicker and more convenient. In comparison to typing in passwords or PINs, facial recognition requires a far lower number of touchpoints. It is compatible with multi-factor authentication, which provides an additional layer of security verification.

Accuracy that is much improved

Just using a person’s phone number, e-mail address, postal address, or IP address to identify someone isn’t as reliable as using just their face instead. Facial recognition is more accurate. As an illustration, the vast majority of exchange services, ranging from equities to cryptocurrencies, currently rely on facial recognition to secure their clients and the assets they hold.


The accuracy of online facial recognition varies based on the algorithm that is being used as well as the conditions that are being tested. It might seem like a lot when you hear that the accuracy is 99.63%. However, the level of accuracy that is acceptable depends entirely on the size and the context. For instance, it is difficult to define what constitutes an acceptable error margin whenever we examine that figure within the context of security checkpoints.
