In the era of digital transformation, the need of the hour is security as well as usability. This technological innovation is one of those about which global headlines have been heard. Right from unlocking your smartphone to high-security surveillance at airports, it is just the most sophisticated system for all your biometric face recognition. But as is with any innovation, there are huge privacy concerns over the facial recognition technique. The following paper explains what a facial recognition system is, how it works, which companies are involved, and what the general application implications on privacy are.
What is a Facial Recognition System?
It is the technology that identifies a person using his facial features or verifies the identity of a person. It uses biometric face recognition by detecting facial features like the distance between eyes, jawline, and facial contours. This data is compared to a database of stored faces to verify whether there is a match. It can be applied both in security, law enforcement, and even personal devices.
Unlike other means of identification, such as a password or a PIN, facial recognition does not depend on physical contact or active interaction from the individual. This generally makes it easier and, in most cases, safer. Technology has now been integrated into a broad range of sectors that vary from an automated face recognition system used at an airport to the security features of a smartphone.
What Is Biometric Face Recognition?
An application of biometric technology relies on unique features of a person’s face. Biometric refers to measurements and analysis of physical or behavioral characteristics used for identification purposes. For facial recognition, it is concerned with the measurement of distances between such key facial points as the eyes, nose, mouth, and chin through which a unique “facial signature” or “template” is then created.
Unlike a password or PIN, which can be forgotten or stolen, biometric data is unique to an individual. It’s more reliable and secure because it would be much harder to replicate or fake a person’s face as opposed to a password or token.
How does a facial recognition system work?
A Facial Recognition System uses complex algorithms for processing and comparing facial data. The process normally involves a few general steps:
- Detection: The very first step of the process involves detecting a face within an image or video. This is generally done by making use of machine learning models which can detect whether a face exists based on its patterns and features.
- Analysis: After facial recognition, it goes for deeper processing of many facial landmarks in detail: the distance between two eyes, nose width, and curves of the jawline. This processing gives fa ace template-a mathematization representation of one’s distinguishing features.
- Comparison: The facial template is then compared to a database of known templates, which can range from solely local on the device to centralized in cloud-based servers or law enforcement databases.
- Identification or Verification: The final process can be identification, where one compares the face to an identity that has been found in a database, or verification, where confirmation is received as to whether that person is indeed who he says he is. Identification is performed mainly in surveillance public spaces or places. Verification usually occurs much more frequently in private devices such as a cell phone or security apparatus.
Who was the inventor of the Facial Recognition System?
The first Facial Recognition system was discovered during the 1960s. An American mathematician and computer scientist, Woodrow Wilson Bledsoe, came up with the first automated face recognition system. Bledsoe’s biometric facial recognition systems were novel because they represented the use of automation where a system recognizes and identifies a human face with the help of physical features.
Ever since then, this technology has been developed further. For example, in the 1990s, the United States National Institute of Standards and Technology developed facial recognition technologies with high accuracy and the same was implemented in security and law enforcement agencies.
The industry uses biometrics to a large extent in all kinds of industries; facial recognition goes from government surveillance to consumer electronics. Tech giants like Apple and Google have now integrated these systems into their products for better security and user experience.
Companies for Facial Recognition Systems
Most of the companies offer facial recognition systems for different types of applications. The companies are developing software, hardware, and installation services to design facial recognition systems and install them in both private and public domains.
Some of the most well-known companies in this category include:
- Clearview AI: While Clearview AI has also gained quite bad fame for the terrible quality of the facial recognition it offers, almost all of these law enforcement agencies around the globe were using its very powerful identification service. This web-scanned photograph from any web corner that’s available on the various social media websites first before cross-checking with its ginormous database with this face.
- Face++: Among these leaders are faces++. The solutions provided by its product include more, such as some other solutions concerning different sectors of recognition in retail, etc.
- NEC: The one major company involved is NEC, a software or hardware that provides solutions for gaining access and monitoring that government and even corporate clients could implement.
- Cognitec: The company specializes in face recognition software and provides border control, law enforcement, and security applications with solutions.
Benefits of Facial Recognition System
Facial recognition systems provide many advantages that make this technology quite popular. Some of the key benefits are mentioned as follows:
Enhanced Security: No one can break down; therefore, a stronger layer of security is ensured. Unlike your password or your PIN, they cannot carry your face or forget that.
Convenience: This is convenient. It can very easily authenticate a user with an easy-frictionless procedure for recognizing anybody. Installation on smartphones using its facial recognition system can effortlessly unlock the phone by passwords. Or even better, use a fingerprint.
Reduced Fraud: They reduce cases of identity fraud and theft since the check of a person’s identity comes through recognition by face by the biometrics system. This comes in handy, particularly with organizations that are linked to finance or governmental services as well.
Non-Intrusive: It doesn’t rely on touch, such as fingerprint detection or iris identification. So it is very hygienic and has simple application scenarios to be used specifically in hospital rooms and aeroplanes.
Relative Cost: The hardware and software installation costs are not very high in the facial recognition system, but sometimes it may cost a bit high compared to other types of biometric systems, such as fingerprint scanning or retinal scanning. Mostly they are inexpensive but need maintenance quite frequently.
News and Privacy Issues in Facial Recognition System
Though there are many advantages facial recognition system bears to its credit, serious concerns regarding its privacy have long been raised especially at a time the system is so much in a popular trend today. Facial recognition system news stories often pointed to some of its complications and ethical matters associated with applying the system.
1. Mass Surveillance
One of the issues most associated with the facial recognition system of biometrics mass surveillance is that. This makes governments and law enforcement agencies use facial recognition to track individuals in public spaces. Therefore, it is a question of whether a person has the right to be anonymous in public. Often, the use of automated facial recognition systems in public places such as airports, streets, and stadiums occurs without any clear consent from the individuals, and hence, it gives a lot of fear for living in a “Big Brother” society.
2. Accuracy and Bias
The biometric facial recognition systems have also raised significant issues of accuracy and bias. It has been found that in some research works, facial recognition in some races and genders is relatively less accurate than some age groups. Because of this reason, racial bias was claimed on the facial recognition systems installed by law enforcement agencies. A false positive may result in unlawful arrest whereas a false negative may lead to denial of services. This can lead to some serious issues in the marginalized communities.
3. Data Security
Huge risks regarding security information surround the collection and storage of biometrics. Should hackers ever crack into the database storing data from the facial recognition system, one could quite literally steal identities or use that information for whatever nefarious intention. Once more, whereas the password would change in the case of a breach, once the information is compromised, this one is permanent; therefore, one can’t “reset.”.”
4. Consent and Control
Few people would know that their faces, scanned and put away by some company or government are being used for facial recognition systems. Today, there is a problem related to consent. Will people be in control of their face data? Will they have the choice to accept or decline all facial recognition systems?
Conclusion
One of those technological breakthroughs, surely, that someday will revolutionize the world of identification, security, and convenience. Biometric face recognition systems are today used in everything, from mobiles to public surveillance. The facial recognition system has attributes like safety, convenience, and reduction of fraud, but it has serious issues with privacy and ethics that cannot be overlooked. With increasingly powerful technology, policymakers, companies, and consumers need to understand what such evolution would mean to privacy, security, and civil liberties.
Only strong regulation, transparency, and safeguards in proper regulation of technology ensure that we could be allowed full access to the biometrics of these facial recognition systems with the utmost respect and safety to privacy.
