Introduction and functionality of biometric gait recognition

In recent years, technological developments have occurred at a remarkable pace, and this has led to the use of various patterns in the authentication process. One of the newest biometric systems for identifying people is authentication through walking pattern, which identifies people using features such as stride length. This method is not very common compared to other biometric identifiers such as fingerprint, face recognition, iris recognition and palm recognition and still remains unknown to many people. Therefore, in this article, we will examine biometric recognition through walking and how it works.

What is biometric gait recognition?

Gait detection is one of the biometric methods that authenticates people using physiological characteristics such as stride length, stride frequency, and stride pressure. These features are completely different and unique in each person and today they have become one of the biometric identifiers. This biometric authentication system was developed for the first time by researchers from Manchester and Madrid universities. In this method, people walk on a pad that is placed on the floor for identification, and their walking pattern is recorded.

One of the most obvious advantages of this method is no need to remove the shoes, which allows the identification of features with the presence of shoes. According to the research of Omar Kostila Reiz, who is the leader of the research in the field of identifying the identity of people through the walking pattern, each person shows about 24 unique characteristics while walking, which leads to the extraction of a specific walking pattern. He helps. Walking pattern recognition is known as one of the most effective methods to increase security in military and security organizations, because its accuracy is very high.

Biometric gait recognition steps

The method of biometric walking detection, similar to other biometric identifiers, includes several steps as follows:

1. Data collection

In the first step, biometric data is examined and collected. Gait detection data includes features such as step length, step frequency, and foot pressures. These features are used as collected data in the next steps.

2. Data preprocessing

The data collected in the pre-processing stage means the extraction of key features and the removal of noises, which in a way causes the standardization of the data. After this step, the data is stored in the system and used to identify people.

3. Comparison and matching of data

By walking on the pad, people provide their biometric information to the system to be compared with existing patterns. Each person’s data is carefully matched with the patterns stored in the system to confirm his identity if there is a similarity.

Advantages of biometric gait recognition technology

The use of biometric gait recognition technology has many advantages, including the following:

Increased security

Walking pattern recognition is one of the most effective ways to increase and improve security. This technology is used in airports, military organizations, security institutions and banks as an ideal option to provide security and help prevent fraud and fraud. In addition, this technology is able to identify people who have committed crimes and report their presence to institutions such as banks. Also, this method is used to identify criminals and terrorists and is used in judicial systems. By using this technology, it is possible to prevent unauthorized people from accessing the privacy of users and increase the level of security.

Reducing human interaction

In this technology, all steps are completely performed by artificial intelligence and automatically; Therefore, the need for manpower is minimized. Also, contact and direct interaction between people will not be necessary. This feature helps to comply with health protocols and makes it one of the best biometric methods for sensitive and medical centers.

High accuracy

Human gait characteristics are completely unique and no two individuals can be found with similar movement characteristics. Also, due to the high variety of these characteristics during movement, it is not possible to fake them and each person has his own movement pattern. Therefore, identifying users through this biometric method is done with very high accuracy, and by observing the movements, the user can be identified.

Challenges of biometric gait recognition technology

This identity identification method faces two main challenges: change in the direction and angle of walking and change in the person’s appearance. These problems arise for various reasons, such as changing clothes or carrying bags and other items, and can affect the performance of identity recognition. However, solutions are being developed to deal with these challenges that can solve these issues by using artificial intelligence algorithms.

Application of biometric gait recognition technology

As mentioned, gait pattern recognition is not very common, but it has many applications and is used in identifying people in airports, offices and many other places. Based on the research, this method has been able to fully identify people in different environments. Among the most important applications of biometric recognition through walking, the following can be mentioned:

1. Law enforcement

In judicial systems, biometric identification such as gait pattern recognition is used to match data with people’s identities. For example, this method is used to increase security at borders and other places to identify criminals.

2. Healthcare services

People use this biometric ID to verify their identity in medical centers such as hospitals, pharmacies and clinics in order to benefit from health and government services.

3. Security

Biometric gait detection is significantly effective in preventing unauthorized access to computer systems and networks. This method helps to solve problems such as forgetting password and card and prevents theft and forgery of these items.

4. Commercial goods

People can use this biometric system to access services and verify identity in various businesses such as restaurants, sports organizations, retail stores, etc.

summary

Walking pattern detection is one of the biometric methods to identify people’s identity, which we have investigated and explained in this article. This method is known as an effective tool to verify identity and increase security in different environments. Although this method has not been widely used yet, due to its significant advantages, it is expected that it will become more popular and its application will increase in the future.
