Have you ever heard of sweat recognition before upgrading your body "password"? 【full text】

With the gradual improvement of information security awareness of security exhibition network technology , people now have more and more secret protection methods on smart devices. From the early pattern and password unlocking to the fingerprint and voice unlocking that have been developed step by step in recent years, countless mobile phones have now launched new trendy unlocking methods such as face and iris, and the secret protection method that uses biometrics as the main method is gradually Into thousands of families.

Speaking of biometrics, everyone knows that it is a brand new technology to obtain the "password" by exploring the mysteries of the human body. In our complex human body, there are a lot of special biological information. Using this information as a secret protection method and verification method can undoubtedly better guarantee the safety and convenience of people's lives.

At present, fingerprints, voices, faces, irises, etc. are all common biometric means. They are favored by enterprises and users because of their simple acquisition, convenient application, and outstanding advantages. But in addition, there are some biometrics that are not known to many people who are eager to rise, and sweat recognition is one of them.

Biometrics are popular, and sweat can also be used as a password

Sweat recognition, as it literally means, is a method of recognizing the use of sweat secreted by the human body as a security code. Even today, where many biometric methods are used, I believe that many people will still ask, can sweat also serve as identification information? The answer is yes!

Sweat, like fingerprints, voices, irises, etc., is actually important biological information on our bodies, which contains many personal characteristics. Relevant scientists have revealed that sweat as a skin secretion, its constituent amino acids are different from human DNA. Using these features for biometric recognition is even safer than face recognition.

In 2017, the associate professor of the Department of Chemistry of the State University of New York at Albania proposed the concept of sweat certification. It published an article in a magazine that discussed the feasibility of applying sweat recognition technology on smart wearable devices or smartphones. And related research proves that sweat recognition has significant application value.

He said that as long as the sweat information collected during the day is stored in the smart device, when the user holds the device in his hand or wears the device on his body, he can automatically perform identification and authentication. This identification method is not only very convenient and effective, but also can further increase the number of people using biometrics for identification.

Safer or more convenient, what are the advantages and disadvantages of sweat recognition

So, as a new type of biometrics, is sweat recognition really as good as the professor mentioned above? What are its advantages and disadvantages? Compared with several "brothers" that have been widely used, is it competitive?

To answer these questions, we have to think in terms of its own characteristics and specific applications of sweat recognition.

First of all, from the perspective of the characteristics of sweat recognition, we already know that sweat is sexual. This aspect determines that it can be used as an effective biometric method, on the other hand, it also shows the safety and accuracy of its recognition. Compared with passwords, fingerprints, etc., which are easy to be stolen, the accuracy of face recognition is not high, and sweat has obvious advantages in these aspects.

Secondly, in terms of the specific application of sweat recognition, if you want to use sweat authentication, you need to measure the user's sweat status at different times within a day many times, which makes its information collection and application more troublesome. At the same time, different ages, genders, races, physical characteristics, occupations, etc. will also lead to different composition ratios and amounts of sweat, all of which lead to greater inconvenience and limitations in the application of sweat recognition. Therefore, in application, the shortcomings of sweat recognition are more prominent.

In summary, sweat recognition does have a strong advantage in safety and effectiveness, but there is a big gap compared to other biometric methods in terms of application convenience and limitations. In the future, sweat recognition may have a long way to go before it can truly enter people's production and life.

Although not, but these fields may be applicable in the future

Of course, although sweat recognition is not, it does not hinder our exploration and expectation of its application. Aside from convenience, sweat recognition has a strong advantage in value and security, enough to make it a place in the future biometrics market.

For example, sweat recognition technology can be applied in the field of intelligent rehabilitation and medical. Various substances of human metabolism are stored in sweat, and these substances can be used as both identity authentication information and health monitoring information. In the future, the application of biometrics in medical and intelligent rehabilitation wearable devices can effectively monitor and check the physical condition of the human body at the same time of identification and certification.

As another example, sweat recognition technology can also be applied to military spot checks, traffic drunk driving, etc. Alcohol existing in sweat can be reflected through recognition. Based on this, sweat recognition can penetrate into these fields, protect the overall quality of the military, and assist in traffic and drunk driving inspections. Effectively use the full value of sweat recognition.

This shows that sweat recognition may not be easy to enter into an ordinary family, but it is still very simple to obtain a place for one party to use. We hope that sweat recognition will accelerate its popularity and development in the future, and we believe it will usher in a day of rise and growth.
