What is parental certification?
Authentication, also known as "verification" and "authentication", refers to the confirmation of the user's identity through certain means.
The purpose of authentication is to confirm that the user who claims to be a certain identity is indeed the claimed user. In daily life, authentication is not uncommon.
For example, we can generally determine each other's identity by looking at each other's documents. Although the practice of confirming the identity of the other party in daily life also belongs to "authentication" in a broad sense, the word "authentication" is more used in computer, communication and other fields.
There are many authentication methods, which can be basically divided into: authentication based on * * * shared key, authentication based on biometrics and authentication based on public key encryption algorithm. Different authentication methods have different security levels.
Enjoy the key based on * * *.
Authentication based on * * * shared key means that both the server and the user * * * have one or a group of passwords. When the user needs authentication, the user submits the password owned by the user and the server * * * through input or through the device that saves the password.
After receiving the password submitted by the user, the server checks whether the password submitted by the user is consistent with the password saved by the server, and if so, judges that the user is a legitimate user. If the password submitted by the user is inconsistent with the password saved by the server, it is determined that the authentication failed.
