#What is biometric authentication
Biometric authentication is an authentication system that uses physical features and behavioral features. Today it is also used in PC, smartphone, ATM, airport, etc. It is also used for payment at convenience stores as in the experiment stage. However, there are various types even if you go to biometrics and make one cup.
As you can see from the above figure, there are two patterns of biometrics are physical and characteristics of behavior, but on this page I will mainly deal with physical things.
#Practical example of biometric authentication
As mentioned at the beginning, the biometric authentication system has already been used in various places. The most familiar example is a smartphone.Many of smartphones have fingerprint authentication, face authentication, iris authentication etc. introduced. Biometric authentication has few risks of leakage, it is also easy, it has advantages such as okay even if you forget your password, it can be more convenient and safe to use with other authentication methods.
It is also used for settlement in stores. Biometric authentication has many moves to use for settlement by preventing forgery prevention or unauthorized access trouble from the conventional password.
If it is actually introduced at a store, it is expected to be more efficient and simpler, such as shopping can be done with one fingerprint. Using biometrics makes it easier than identifying individuals, if future speeds and accuracy improvements are made, it will be introduced to public transportation and even handbags may have a future that can ride on trains and buses.
#Challenges of biometric authentication
Very useful and useful biometric authentication is also problematic.That is because authentication may fail due to changes in physical condition. It is a case where physical characteristics have changed due to injury, illness, growth, etc. Moreover, it is difficult to make both "0 persons refusal rate" who recognizes himself not himself and "other person acceptance rate" who erroneously recognize another person as the principal to 0, and biometric authentication Is that the acceptance rate of other people is not 0 and there is a possibility of misrecognition.
#Summary
Biometric authentication is excellent in convenience and safety
It can be applied in various situations
There is room for improvement such as improvement in accuracy
#Our opinion
The story of the movie world is becoming a reality. If this Biometrics is introduced our life will change dramatically, I think that shopping and going out will be a more convenient world.
