What methods are used on computers to verify the legitimacy of a user s identity?

The methods commonly used in computers to verify the legitimacy of a user's identity include the following:1Username and Password:

Users will need to enter the correct username and password when logging in to be authenticated. 2.Biometrics:

For example, fingerprint recognition, face recognition, iris recognition, etc., verify the legitimacy of identity by scanning or collecting the user's biometric data. 3.ID Identification:

For example, ID cards, passports and other identity documents, by scanning or reading the information on the ID documents to verify the legitimacy of the user's identity. 4.Digital Certificates:

The legitimacy of a user's identity is confirmed through the issuance and verification process of a digital certificate, which usually contains the user's public key and the digital signature of the certificate authority. 5.Two-factor authentication:

Use two or more authentication methods at the same time for authentication, such as ID document identification and password verification, fingerprint recognition, and SMS verification.

Authentication is the first step of data security, network security and application security, and it is also an important means to ensure enterprise information security. In addition, many technology companies have also launched identity authentication solutions to help enterprises protect data security. Taking the two-factor real-person identity authentication solution launched by Elliot as an example, it is mainly composed of "biometric peripherals + trustme?".

Authentication client + trustlink?The biometric unified identity authentication platform can comprehensively build a mutual authentication mechanism for biometric information and passwords from the user end to the platform layer and the application layer, so as to avoid the risks caused by common, borrowed and stolen use by traditional enterprises in information security management. After deploying this solution, the login is more secure and convenient, and the biometric identification is used instead of passwords, which not only simplifies the login authentication process, but also avoids the trouble of remembering and managing password errors
