Identity authentication system and method

Abstract

The invention provides an identity authentication system and method. The identity authentication method comprises the biological information obtaining and storing step and the authentication step, wherein in the biological information obtaining and storing step, biological information is obtained, numeralization is carried out on the obtained biological information, the numerical biological information is encrypted, encrypted data are processed in a decentralized mode to form three or more data blocks, the data blocks are stored in different storage devices respectively, and each data block does not contain the complete data of the biological information; in the authentication step, the data stored in the storage devices are obtained, the obtained data are combined, the combined data are decrypted, the decrypted data are compared with data obtained after numeralization is carried out on biological information obtained by an identity authentication device, and the authenticity of an identity is authenticated according to a comparison result. The method is applied to authenticating the identity through the identity authentication system. Safety of data storage can be improved, and complete personal information leakage caused by data leakage is avoided.

Description

technical field [0001] The invention relates to the field of identity verification, in particular to an identity verification system and a method for applying the system to identity verification. Background technique [0002] When people leave or enter the country, they usually need to carry out identity verification, such as scanning their fingerprints for identification. The usual practice is that the entry-exit management department obtains people's fingerprint information in advance, such as pre-scanning people's fingerprints when making entry-exit documents, digitizes the scanned fingerprint image, and stores it on the server of the entry-exit management department . When people leave or enter the country, they scan their fingerprints on the fingerprint scanning device. After the fingerprint scanning device obtains the fingerprint image and digitizes the fingerprint image, it compares it with the fingerprint information stored in the server of the entry-exit management...

AI Technical Summary

Problems solved by technology

However, due to the different password requirements on many different systems and platforms, the passwords stored in different systems are often different, causing difficulties in people's memory and management

[0004] Moreover, if the data is stored on a single network system, it will bring great risks to the security of the data

For example, external attacks, hackers, or viruses on the network system will cause data leakage, and data management loopholes will also lead to data copying and theft, and data may also be accidentally or maliciously modified, stolen or sold, lost, etc.

In addition, the unreasonable use of data managers, for example, one department can freely view the data stored in the server of another department, etc., all of which lead to the leakage of data stored on the network

[0005] Once the fingerprint information of people stored by the entry-exit management department is leaked, it will cause the leakage of people's personal information

Moreover, once people's fingerprint information is used by criminals, it will also cause great harm to society
