Computers use facial-recognition software to identify people by mapping their facial features and comparing that information with the database stored in these programs, and this technology has recently become the safest tool for many users.
In this article, we will learn about this technology and how it works and its main advantages and disadvantages.
What is face recognition technology and how does it work?
Facial recognition systems use several measurements and techniques to scan faces including thermal imaging, 3D facial mapping, unique facial indexing (also called facial features), geometric aspect analysis of facial features, and distance mapping between key facial features. To analyze the surface texture of the skin.
Facial recognition technology is included in biometrics. Other examples include fingerprint scanning techniques and iris scanning systems.
How technology started
This technology was used when the iPhone X was launched which brought with it this groundbreaking technology. At the time, most people saw this pioneering technology as something of science fiction. Yet over the past decade, facial recognition techniques have become not only viable and sustainable but also widespread.
You will now find it very difficult to read a newspaper these days without seeing articles about this technique.
The system can also manually record the coordinates of facial features such as nose, hairline, mouth, and eyes, and technicians have added these measurements to a database so that the system has the ability to retrieve the stored image from the database which is very similar to a person when they are provided with new photographs of him.
At the time, facial recognition techniques were severely limited as well as the slow speed of computer processors, but the process of studying biometrics was viable as the first step in achieving this technology.
Later, developers have taken facial recognition technology to other directions, used by many industries for security purposes, and law enforcement agencies, in particular, have found the system a boon because it will help keep communities safer.
Uses of facial recognition technology
Face Recognition has a variety of applications but is widely used for security and law enforcement purposes. It is used at airports to search for individuals suspected of crimes and also to compare passport photos with personal faces to confirm identities.
Law enforcement authorities also use face recognition programs to identify and arrest people who commit crimes. They have been used in several states in America to prevent people from obtaining fake IDs or forged driving licenses, and some foreign governments have even used identification technology. To the face to eliminate voter fraud.
Pros and cons of technology
This technology has several advantages when compared to other biometrics techniques where facial recognition does not require physical contact.
This new technology easily captures facial images from a distance and analyzes them without having to interact with the person or user. Therefore, a user cannot successfully imitate someone else.
In addition to being a much cheaper technology as it is not limited to the processing as much as with other biometrics knowledge techniques.
Although this technology has its advantages, there are some disadvantages associated with facial recognition technology, and engineers are now working around the world to fix this problem. The system can identify individuals only when the lighting conditions are favorable. When the person’s face becomes slightly blackened or is in insufficient light, it will negatively affect the accuracy of the application to identify and identify the person.
The Future of Facial Recognition Techniques
Facial recognition technologies have become a modern city and have become one of the most popular technologies that will change our daily lives. Soon we will use our faces to book trains, pay for groceries, and even pass through airport security.
In China, people are already using their faces to reach their office buildings and even to authorize withdrawals from ATMs. High-end hotels and retail stores in Europe have used facial recognition technologies to identify celebrity customers to offer them special treatment.
Australia, not far from other developed countries, is now seeking to install a system at its airports that will allow airlines to bypass security without requiring their passports, and these systems are beginning to appear in many US airports as well.
Forensic agencies and law enforcement agencies also use facial recognition techniques to identify suspects and bodies for unidentified persons.
Retailers will use facial recognition systems as a service to prevent theft of stores, which in turn will help them protect the interests and safety of their consumers.
The bottom line is that facial recognition techniques can change the way we do things. However, how to use this technology without invading users’ privacy is still a topic of discussion.
Many industries and agencies around the world now embrace facial recognition techniques, bars have begun to be used to catch underage drinkers, and schools are now implementing them to take attendance.
This will make acquiring techniques reorganize our daily lives in the next few years, hoping to progress for the better.
