What is biometric turnstile?

Biometric turnstile is a kind of pedestrian turnstile gate integrated with a variety of biometric equipment such as a fingerprint scanner, face recognition camera, etc. In this way, the pedestrian turnstile gate has diversified identification methods, realizes various functions, and meets the use needs of various occasions. According to different identification methods, the pedestrian turnstile gate can be divided into turnstile gate with card reader, QR code turnstile, biometric turnstile. Today, we’ll mainly learn about biometric turnstile.

Say it in more detail, the biometric turnstile is based on the traditional intelligent turnstile gate, which adds a variety of biotechnology such as fingerprint recognition, finger vein recognition, face recognition, palm vein recognition, and iris recognition, so as to make the turnstile gate diversified identification methods and meet the needs of different occasions. For example, if the biometric turnstile is used for airport security inspection, you can show your ID and boarding pass and pass through the self-service turnstile gate. Compared with the traditional boarding process, the biometric turnstile can greatly shorten the waiting time.

The biometric identification method is characterized by identifying the biometrics of the passing people, with high reliability. For example, the face recognition method uses visible light to obtain face image information. During the movement of pedestrians, the camera can actively capture the pedestrian’s face information and quickly identify the pedestrian’s traffic authority. Biometric turnstiles in different places use different identification methods, some use a single identification method, and some use multiple combinations.

Biometric turnstile application site

Biometric turnstile is mainly used in the station, airport, subway ticket checking, and examination, etc. This setting can effectively ensure the smooth passage of passengers with valid tickets, improve work efficiency and save financial expenses. In addition, biometric turnstiles are widely used in many fields, such as office buildings, cinemas, exhibition centers, libraries, stadiums, and sightseeing attractions, which can not only realize the efficient control of channels, but also meet the beauty and practicability of indoor and outdoor decoration design.

Today’s airports can “face recognition” customs clearance. Subway stations have already started “face recognition” ticket checking. Office buildings use “face recognition” to manage attendance. Residential areas use “face recognition” to enter the gate. Face recognition not only brings convenience to people, but also ensures the safety of entering staff.

Nowadays, many industries use face recognition turnstiles to replace manual services to carry out real-name authentication, which can establish efficient, convenient, fast, and accurate management methods for the entrance and reduce the cost of manual service management methods.

The use of face recognition turnstile can develop surveillance cameras from the front end and connect the collected statistical data with the public security organs, which is conducive to the reconnaissance work, avoid and a crackdown on criminal personal behavior, improve the safety of public places and improve the efficiency of public security personnel in handling cases.

Airports, subway stations, customs, and other urban public transport places, the face recognition and identity ID number city real name authentication integration, visitors self-service security check or check clearance, instead of manual service detection, and identification speed is very fast, improve the convenience of passengers travel.

The office building is equipped with a face recognition turnstile, which can establish an intelligent office. Customers can say goodbye to the traditional method of swiping credit cards. They can only go in and out according to the identification face. This not only strengthens the service management of the office building, but also improves the customer experience. Together, the company and property management can also use the statistical data collected according to the gate to improve the management system.

The application of face recognition turnstile in the residential area makes the security mode of the residential area more modern. It replaces the role of security personnel, identifies more accurately and without notes than security personnel, creates a convenient and fast entry for the residents of the residential area as soon as possible, and prevents the illegal entry of migrant workers. When the residents can’t easily find the card, don’t bring or lose the door card with a large luggage bag, I’m also worried that if I show my face, I can enter the door. It’s very convenient and can improve the residents’ sense of belonging to the community.

Next, we just briefly introduce two widely used biometric turnstiles, fingerprint turnstile and face recognition turnstile

Fingerprint turnstile

Fingerprint turnstile is a widely used type of biometric turnstile, but no matter which pedestrian turnstile gate has unique advantages and disadvantages, it is just that the customer’s choice of specific requirements is different in specific occasions in practical application. If you want more detailed information, please check out another article: fingerprint turnstile

Advantages of fingerprint turnstile

The reason why fingerprint turnstile is used in access control management is that fingerprints are unique features of the human body, and their complexity is enough to provide sufficient features for identification;

If we want to increase reliability, we just need to register more fingerprints and identify more fingers, up to ten, and each fingerprint is unique;

Fingerprint turnstile is mainly used to scan fingerprints fast and easy to use; It saves time and avoids the trouble caused by forgetting to bring the card or losing the card.

When people read fingerprints through the fingerprint turnstile, users must contact their fingers with the fingerprint acquisition head. Direct contact with the fingerprint acquisition head is the most reliable method to read human biometrics. This is also the main reason why fingerprint identification technology can be applied to pedestrian channel management.

The fingerprint acquisition head adopted by the fingerprint turnstile can be customized into miniaturization, which is easier to be embedded and used in combination with the turnstile gate.

Disadvantages of fingerprint turnstile

Some people’s fingerprints are difficult to image because they have few fingerprint features;

In the past, the use of fingerprints in criminal records made some people afraid to “record fingerprints”. However, in fact, the current fingerprint identification technology can ensure that it does not store any data containing fingerprint images, but only stores the encrypted fingerprint feature data obtained from fingerprints.

Every time the fingerprint is used, the user’s fingerprint marks will be left on the fingerprint acquisition head, and these fingerprint marks may be used to copy the fingerprint.

It can be seen that fingerprint turnstile is the most convenient, reliable, non-invasive, and cheap biometric technology solution at present, and has great potential for the application of all walks of life.

Face recognition turnstile

Face recognition turnstile is a powerful access control pedestrian turnstile gate.

Face recognition gate is the application and development of a face recognition system in the turnstile gate. Compared with other general biometric turnstiles, IC/ID card turnstile gates, and QR code turnstile, face recognition turnstile have significant advantages and innovation. Compared with manual service identification, face recognition turnstile replaces the traditional manual service method to carry out real-name authentication, which has higher efficiency and more accurate identification. Compared with fingerprint recognition, retina, palm print, and other biometric technology gates, face recognition turnstiles also have many advantages.

1. The face recognition turnstile is not mandatory: the customer does not need to be forced to cooperate with the professional face collection machine and equipment, and the system software can basically obtain the face image without the customer’s awareness.

2. High recognition degree of face recognition turnstile: for fingerprint verification or iris recognition, an electronic device liquid level sensor must be used to collect fingerprint recognition, or infrared induction must be used to collect retinal images. This unique collection method is very easy for others to find and will be hidden. However, the face recognition turnstile completely uses invisible light to obtain the content of face image information, which is not easy to hide.

3. Non-contact of face recognition turnstile: the customer does not need to touch the machine and equipment immediately. The system software can basically obtain the facial image without the customer’s active cooperation, saving time and effort.

4. High concurrency of face recognition turnstile: it can carry out express sorting, discrimination, and identification of several faces in specific application fields.

5. In addition, the face recognition turnstile is also in line with the visual characteristics, the characteristics of “judging people by appearance”, and its advantages such as convenient use and visualization of results. Compared with the ID number card, credit card certification, passport visa certification, QR code picture, and IC/ID card certification, the face recognition turnstile does not need to carry a card or valid certificate.

It only needs to arrive at the spot to carry out the certification without having to lose the card or valid document to authenticate the vehicle, and it does not need to carry out the “gate fence”. The system software can basically obtain facial images when customers do not actively cooperate with each other, saving time and effort.

Identification mode of biometric turnstile

What are the identification methods of pedestrian biometric turnstile? Let’s briefly introduce it.

1. Fingerprint identification

Fingerprint identification mainly identifies the operator or the operator according to the lines, details, and other information of human fingerprint. Thanks to modern electronic integrated manufacturing technology and fast and reliable algorithm research, fingerprint identification has begun to enter our daily life and become a more in-depth, widely used, and mature technology in biometrics

2. Finger vein recognition

Finger vein recognition is a kind of vein recognition. Firstly, the personal finger vein distribution map is obtained by a finger vein recognition instrument, and the characteristic values are extracted from the finger vein distribution map according to the comparison algorithm. Through near-infrared light irradiation, the image of the finger vein is obtained by a CCD camera, the digital image of the finger vein is stored in the computer system, and the characteristic values are stored.

3. Face recognition

Face recognition is to recognize the input face image or video stream based on human facial features. Firstly, judge whether there is a face. If there is a face, further give the position and size of each face and the position information of each main facial organ. Based on this information, the identity features contained in each face are further extracted and compared with the known faces, so as to recognize the identity of each face.

4. Palmar vein recognition

Palmar vein recognition is another mature technology in this field. When using the palmar vein for identity authentication, the image features of a palmar vein are obtained, which only exist when a palmar vein is living. In this system, the non-living palm can’t get the vein image features, so it can’t be recognized, so it can’t be fake.

5. Iris recognition

Iris recognition technology has now been widely recognized. Iris recognition technology is more accurate, but sometimes there will be recognition obstacles when the device scans the retina.

The biometric turnstile needs to customize the appearance and function of the intelligent pedestrian turnstile gate according to the needs of different occasions.

Biometric technology

Biometric technology is a solution for authentication based on human body characteristics. It is also a popular verification method applied to the intelligent pedestrian turnstile access control system. The biological characteristics of the human body include fingerprint, sound, face, retina, palmprint, skeleton, and so on. The core of the so-called biometrics is how to obtain these biometrics, convert them into digital information, store them in the computer, and use reliable matching algorithms to complete the process of verifying and identifying personal identity.

Biometric technology is widely used, especially in the field of security. At present, the main biometric technologies include fingerprint recognition, face recognition, iris recognition, speech recognition, and signature recognition. Please see the following for the analysis of advantages and disadvantages.

1. Fingerprint identification

Fingerprint identification is the most widely used biometric technology, especially in the field of pedestrian access gate prohibition and attendance.

Advantages: it has a long history, mature technology, small equipment, and low cost. It is widely used in the fields of attendance, access control, automatic identification, etc;

Disadvantages: contact is required, and there are invasive and health problems. In addition, fingerprints are easy to wear, and the degree of dryness and wetness of fingers will affect the effect of identity recognition;

Summary: The development of fingerprint recognition technology involves many disciplines, such as image processing, pattern recognition, machine learning, computer vision, mathematical morphology, wavelet analysis, and so on. An automatic fingerprint identification system (AFIS), which includes fingerprint image acquisition, processing, feature extraction, and comparison and equivalence modules, is the most accepted product in this field.

2. Face recognition

Face recognition is a very active research field in recent years.

Advantages: it has the characteristics of good intuition, convenience, friendliness, and easier acceptance;

Disadvantages: the existing face recognition system can achieve satisfactory results under the condition of user cooperation and ideal acquisition conditions. However, when the user does not cooperate and the acquisition conditions are not ideal, the recognition rate of the existing system will drop sharply. In addition, the user’s face changes, which will greatly reduce the recognition effect;

Summary: face recognition includes two research fields: face detection and faces recognition. There are four kinds of face detection algorithms: knowledge-based, feature-based, template-based, and representation-based. Face recognition needs to use facial stable features for recognition. Such algorithms include methods based on LDA, PCA, ICA, Gabor, and feature face. At present, the research direction of face recognition has entered the stage of 3D face recognition.

3. Iris recognition

Iris recognition technology is recognized as the most accurate recognition method among the existing biometric means.

Advantages: high accuracy, anti deception, high practicability, and no contact. The feature template is formed by using the features of the iris region (ring, wrinkle, spot, and crown) in human eye image, and the recognition is completed by comparing these feature parameters;

Disadvantages: iris image acquisition equipment is expensive and troublesome. However, because it has high accuracy and can provide accurate identity, it is the first choice for effective identity verification;

Conclusion: iris recognition is an eye-related biometric with low human interference. It uses quite common camera elements and does not require the user to contact the machine. In addition, it has the ability to achieve higher template matching performance. Therefore, it has attracted the attention of all kinds of people.

4. Speech recognition

Speech recognition is the application of a speaker’s voice and linguistic patterns based on biological and behavioral characteristics. It recognizes the speaker by analyzing the unique characteristics of speech, such as the frequency of pronunciation.

Advantages: easy to use, large distance range, and simple installation. Only one microphone is needed to receive the signal;

Disadvantages: low accuracy, limited application range, easy to be affected by background noise, physical condition, and emotion. In addition, the recording of the same person will also deceive the speech recognition system;

5. Signature recognition

Signature recognition is a biometric technology based on behavioral characteristics. It makes identity confirmation by analyzing the handwriting of the signature and the pressure and speed of the signature process.

Advantages: identification of different styles;

Disadvantages: a signature is related to mood, writing tools and other factors, especially the signature can be forged and the anti deception is poor;

Summary: signature recognition can be divided into online signature and offline signature. Online signature is the collection of signature samples by handwriting pad. In addition to collecting the coordinates of writing points, some systems also collect data such as pressure and pen holding angle; Offline signature is to enter a signature sample through the scanner. Obviously, offline signatures are easy to forge and difficult to identify. Online signature is not easy to forge because of dynamic information. At present, the recognition rate can also reach a satisfactory level.

At present, fingerprint recognition is the most widely used identity recognition technology, and face recognition has been paid more and more attention. The innovative pedestrian access gate identity recognition technology mostly adopts fingerprint recognition, face recognition, and iris recognition, which can meet the requirements of users such as attendance and security protection, and the biometric turnstile gate can be customized.

Selection of biometric turnstile

Biometric turnstile has developed very rapidly in recent years, such as fingerprint turnstile, face recognition turnstile, etc. there is confusion in the factors that users consider when choosing biometric turnstile, resulting in the inability to confirm which technology is really suitable for them. The following key factors are to be considered in the selection of biometric turnstile.

1. User acceptance

The most important thing for all product solutions is user acceptance. For example, many users will refuse such fingerprint turnstile on the grounds that fingerprint identification is not hygienic enough, and there are certain requirements for identifying users’ fingers. In this case, non-contact technology has developed rapidly. Therefore, understanding which patterns are acceptable to users is the key to deploying biometric solutions.

2. Security

Like the hidden dangers of network security, the popularity of biometric solutions has become the target of criminals trying to destroy. Many criminals enter interactive instructions to access restricted areas or direct attacks have become serious problems. Therefore, when choosing biometric turnstiles, we should consider the security of the biometric turnstile.

3. Accuracy

With the maturity of technology, the application of biometrics is constantly improving, but it is still one of the most fundamental needs of customers. To measure the accuracy of a product, there are usually indicators such as false acceptance rate (FRR), false alarm rate, recognition rate, false rejection rate (far), etc. Although face recognition has high convenience, its recognition accuracy will be affected by environmental light, recognition distance, and other factors. When users change the face by means of makeup and cosmetic surgery, it will also affect the recognition accuracy.

4. Cost

Cost is a common consideration for users, especially when selecting the best and most effective identification hardware, cost is often the decisive factor.

5. Environment

The installation environment has a great impact on the use of the product. The recognition rate of face recognition or iris recognition will be reduced in a dark environment. Before deciding which biometric turnstile to choose, the environmental factors must be considered, and the environment can be modified when necessary.

6. Trend

Due to the early cost and technical constraints, fingerprint turnstile is the most popular form in the market. However, in recent years, biometrics is becoming popular, especially in the financial and prison industries. Due to the relatively high accuracy, face recognition turnstile and iris recognition turnstile are popular in some high-end projects.

It is worth noting that these elements are only general standards, because there is no single best model in different projects. The most appropriate biometric turnstile can be selected only by fully considering factors such as location, environment, and application population.
