Explain the mechanism and how to apply facial recognition technology today
Facial recognition is a great system that can identify an individual by reading face information.
Because contactless authentication is possible, facial recognition is an authentication method that provides a smart solution when infectious diseases break out like the Corona pandemic.
Therefore, Chiasenow will explain the facial recognition system in detail .
Chiasenow will also detail examples where facial recognition systems are used, so please refer to this article if you are learning about facial recognition systems .
What is facial recognition ?
Facial recognition is a technology that authenticates a persons face and confirms that persons identity.
This is one of the biometrics that have been introduced in various cases. Biometrics include face authentication, fingerprint authentication, vein authentication, and iris authentication.
Biometric technologies such as facial recognition have been widely used in enterprise services, banking that require strong security, and even national infrastructure.
Face recognition and image recognition technology are easily confused with each other.
In the case of face recognition , it usually refers to a technology that detects where a persons face appears from an image and identifies the persons gender, age, and facial expressions.
Today, it is a commonly used technology for marketing purposes.
On the other hand, facial recognition is a technology to verify that you are definitely a particular individual by matching detected facial features with registered data.
Facial recognition differs from other biometrics in that it does not require contact with the device and can perform authentication processing without stopping the work in progress.
In addition, many customers recently consider it an easy to use system with a low false positive rate (false positive rate).
Therefore, facial recognition is becoming more and more popular and widely applied.
Face recognition mechanism
Facial recognition is an authentication method that allows a technological system to recognize a person.
Image compositing is done based on various factors such as the location of features such as the eyes, nose and mouth of the face, the location of the facial region, and the proportions.
In recent years, with the improvement of technology, some technologies that can authenticate when wearing a mask and have a temperature measurement function have become more popular.
Face recognition authentication method
The mechanism of a face recognition system is to detect a face from an image or video and recognize it as a specific individual.
Among them, there is a 2D face recognition system that only takes pictures, and a 3D face recognition system that recognizes three-dimensional faces using an infrared camera.
Visual method of facial recognition (2D authentication)
This is a method of authenticating a specific person by recognizing the position of the faces eyes, nose, mouth, etc. in the image and matching that persons information in the database.
It has the advantage of having many compatible terminals and a wide choice.
However, there are some issues, such as the amount of sunlight hitting the device, that affects the accuracy of the authentication.
Sometimes authenticity cant be done properly depending on the hairstyle and makeup.
New technology method for facial recognition (3D authentication)
It is a system that adds an infrared sensor to the mechanism of a 2D face recognition system and adds functionality that can recognize faces in the form of 3D data.
Because of adding more face recognition functions , the authentication accuracy is higher than 2D face recognition system .
There is no error even when the makeup or hairstyle is changed, and there is an additional advantage that the facial recognition system can work with infrared rays regardless of the amount of light reduced as in the case of identification 2D face .
The disadvantage is that you need a terminal that supports infrared authentication.
Benefits of applying facial recognition system
Facial recognition systems are used in a wide range of situations, from banks that require strong security to office entry/exit management, national infrastructure, and smartphone unlocking.
There are many benefits to using a facial recognition system , including:
- It is possible to enter and exit the room without contact, which is an effective measure against unnecessary contact.
- Fast authentication doesnt require you to carry a card
- Can be installed not only in the office but also in various places such as shops and factories
- No risk of spoofing because proxy authentication is not possible
- The authentication method is not affected by changes in weather
What you can do with facial recognition
If you have read this far, you must have understood the concept of a facial recognition system , next we will learn how to apply facial recognition and what it can do, along with specific examples. body.
1. Facial recognition to Manage in and out of the office, company, home…
If you install a facial recognition system in your office, you can use it to authenticate when entering a room.
Many companies already authenticate with IC card with integrated employee ID card, and some may wonder, Is there any benefit to changing to a facial recognition system ?
In fact, it has the advantage of reducing the burden of paperwork and improving security by preventing others from entering and leaving by spoofing and eliminating the hassle of losing or re-issuing a receipt card. identity form.
2. Facial recognition for member authentication
By adopting a facial recognition system , you can streamline the work of member authentication.
By installing a facial recognition system instead of having the front desk check it out visually, we can control operations during difficult times like a pandemic outbreak while still ensuring safety.
In addition, even at establishments that already authenticate with IC cards, you can prevent unauthorized use of other peoples cards by switching to face authentication.
If you use your membership card at the front desk, you will need to process your application for a new card if you lose it.
In addition, considering the re-issuance procedure, human costs will also be incurred.
But what if you use a facial recognition system ?
Since there is no risk of loss, re-issuance procedures are reduced
Therefore, the facial recognition authentication system replaces card authentication to reduce working hours.
3. Pay with facial recognition
There is also a method of using the facial recognition system to authenticate payments ( facial recognition payments ).
For example, if facial recognition payments could be applied at convenience stores - grocery stores and bookstores, there would be no need for cashiers.
Therefore, there is no need to hire employees, and reduce labor costs.
Furthermore, by using facial recognition information ,
- At what age can you collect customer information?
- Product buying trends by age group
Can analyze those and use them to manage the store.
4. Facial recognition for smartphone login and payments
Apple-provided iPhone X and later are equipped with a facial recognition system called Face ID.
Not only can you unlock it by looking at your smartphone, but you can also pay crypto using the facial recognition system .
5. Facial recognition at the airport
Facial recognition systems have also been adopted at airports around the world, such as airport gates.
In addition to the anti-smuggling function, you can effectively verify your passport.
If you register your facial data first, you can walk to the boarding gate without showing your pass.
6. Face recognition for surveillance – tracking
In long-term care facilities, the safety and well-being of the patient comes first.
If the patient goes out without knowing it can lead to an unexpected accident.
By linking the facial recognition system to the camera in the facility, it is possible to prevent patients from leaving without permission.
At the same time, it is possible to prevent outside intrusion and create a more secure facility.
Facial recognition system and corona prevention measures
Chiasenow has summarized the advantages of facial recognition system over other authentication methods, here is how we apply facial recognition in the current corona disaster.
You should be able to understand why it is currently attracting attention as a means of access control to reduce the risk of infection.
1. Face recognition with temperature measurement function
Some devices come with a camera that can measure the body temperature of a certified person.
By using thermal cameras, it is possible to limit the entry of people with high body temperature.
There is no need for medical personnel or to install another system to measure body temperature.
Can also leave log information such as who, what time and what temperature has moved
2. Facial recognition as contactless authentication reduces the risk of infection
In a normal authentication system that uses card key, password input, fingerprint, etc., it is necessary to touch the system with a finger or lock the card for authentication.
Card keys, etc… are managed by individuals, but because of the many contacts and system authentication, it is possible that bacteria or viruses have been released and infected at that point of contact.
3. Advanced facial recognition can confirm even when wearing a mask
Due to the spread of corona virus infectious disease, these days few people go out without wearing a mask.
Currently, wearing a mask is so common, it is very troublesome to wear and remove a mask every time for facial authentication and above all, the risk of infection during that time is a concern.
Some devices can only be authenticated when the mask is removed.
However, you need to pay attention to the facial recognition rate when wearing a mask.
Depending on the device used for authentication, the authentication rate can decrease depending on the type of mask, so depending on the purpose, facial recognition technology can be reasonably applied.
Summary of facial recognition technology
Facial recognition system is one of the technologies used in many situations.
In addition, because identity verification can be done instantly without contact, quick and secure access control is possible.
Facial recognition systems can be used not only for security management purposes within the facility, but also for logging into many applications and systems.
But what is best when introducing biometrics? If you dont think about it, you may not be able to take advantage of the features of facial recognition .
