Facial Recognition Technology: New Facet of Security

IntroAdvancements in security & surveillance have transformed the industry to a whole new level. As we see people gravitating towards a digital era, the role of cybersecurity comes at the forefront. And the newest innovation of this field can be seen with the introduction of Facial recognition technology.

With new applications cropping up all the time facial recognition has made its name with its unique feature of recognizing a person with a face which is a unique asset of every human being. 

If you want to know who’s at the door, a video doorbell with facial recognition will help you recognize the person provided a photo of that person is already uploaded in the Thanks to facial recognition, billboards now have the facility to serve ads based on an estimate of a person’s sex, age and mood.

The surveillance market has evolved to a new level leaving the traditional cameras on the back burner and making technologies like biometric facial recognition the center stage. Furthermore, the usage of Machine Learning and Artificial Intelligence technologies has greatly empowered facial recognition to become the most effective contactless biometric system.

Let’s explore this technology a bit more to get a better understanding of its working and the security issues it poses for everyone.

What is Facial Recognition Technology?

application 2Facial recognition can be referred to as a technology of identifying or confirming an individual’s identity can be done using their face. Facial recognition systems identify people in photos, videos, and in real-time as well.

It can also be defined as a method of biometric identification that uses body measures like face and head, to confirm the identity of a person through its facial biometric pattern and data. The technology works on collecting a set of unique biometric data of every person and record it in its database that can further be associated with their face and facial expressions to identify, confirm and authenticate the identity of a person.

Unlike other identification solutions present in the market like passwords, verification through email, taking selfies, or fingerprint identification, Biometric facial recognition technology works on handling unique mathematical and dynamic patterns to make this system one of the safest and most effective technology so far.

How Does it Work?

app 3Face recognition technology can capture an incoming image from a camera device in either a two-dimensional or three-dimensional way depending on the features of that particular device. 

It is then compared to the relevant information present in real-time in photo or video in a database, thus being much more reliable and secure than the data obtained in a static image. The biometric facial recognition procedure needs an internet connection as the database cannot be located on the capture device since it is hosted on servers.

As the system compares the faces, it analyses the incoming image mathematically without any margin of error and confirms if the biometric data matches with the person who must be eligible to use a service or is requesting access to an application, system, or even building. 

Purpose of Facial Recognition

Though we have discussed in detail the relevance of facial recognition technology, the functions this technology can perform in real-time is still a question that is yet to be answered. So here we will delve a little more into the relevance of Facial Recognition technology and its usage in the existing market.

application1Access to Mobile: Whether we are talking about unlocking a phone without a password or a specific sensitive application that we need extra security for, in their phones, facial recognition technology comes handy in these types of situations.

Airports and Border Control: Facial recognition is rapidly becoming a familiar sight at many airports around the world. With the increase in the number of travellers holding biometric passports, it is quite common to see them skipping the ordinarily long lines and instead of going through an automated ePassport control to reach the gate faster. Facial recognition technology not only helps in reducing waiting times but also allows helps airports to improve their security.

Finding Missing Persons: It is a common sight to see in sci-fi movies when law enforcement officials use facial-recognition software to catch criminals. But with the way technology is advancing in today’s world, we are not far from the day when using this technology will become a common occurrence. Using Facial recognition, law enforcement can be alerted about the whereabouts of any person using the CCTV database once the person is recognized.

app2Tracking Student or Worker Attendance: Tablets can be used to scan students’ faces and match those photos in the school or college database to validate their identities. More broadly, facial recognition technology can be used for workers to sign in and out of their workplaces, so that employers can track their attendance easily.

Controversy Related to Facial Recognition

Though the technology possesses many unique features to make its relevance known in the market for years to come with its extra security measures and all, it poses a great risk of privacy violation that has put a stop in its advancement to reach other sectors.

Since facial recognition software is still in infancy, the laws governing this area are evolving or practically non-existent at this point. Regular citizens whose information gets compromised have very few legal avenues to pursue these types of cases once wronged.

With the use of facial recognition spreading widespread, the scope for hackers to steal any person’s facial data to commit fraud has also increased.

Despite the risks, the systems are rapidly advancing themselves to make them more secure and hard to duplicate. And once the market will see the potential of this technology, this market will boom by leaps and bounds.
