AI Technical Summary

Technical Problem

The security of user data management in existing technologies is low. Simple hash encryption is at risk of being cracked, especially the salt value generated by random number generation algorithms, which can be cracked through statistical analysis.

Method used

By obtaining the hash values ​​of user identity information and device fingerprints, mapping them to a preset coordinate system, segmenting data blocks and performing nonlinear transformations, a salting factor deeply coupled with user identity and device characteristics is generated. Spatial nonlinear transformation and dynamic coordinate transformation are used to increase the difficulty of reverse inference of salt values.

Benefits of technology

It improves the security of user data management, increases the difficulty of encrypting user data, resists collision attacks and rainbow table attacks, and ensures that the encryption process for different users or data is unique and unpredictable.

Abstract

The application discloses a kind of based on deep salt-based user data management method and system, the method includes: obtaining user identity information and the hash value of acquisition equipment fingerprint respectively to obtain first reference hash value and second reference hash value, and first reference hash value and second reference hash value are mapped to in pre-set coordinate system respectively;The data uploaded by user is divided to obtain multiple data blocks, the hash value of corresponding data block is obtained to obtain multiple initial hash values, and initial hash value is mapped to in pre-set coordinate system according to pre-set mapping coordinate point transformation rule;According to first reference hash value, second reference hash value, initial hash value determines corresponding target coordinate point, and target hash value determined by the target coordinate point according to target coordinate point is mapped to obtain salt factor, to encrypt the data uploaded by user according to salt factor and is managed.The application solves the problem of low security of user data management in the prior art.
