AI Technical Summary

Benefits of technology

This invention relates to an algorithm for validating users' rights based on their own signatures or other factors like location (geographic) where they are located. It allows these signs to be used without being copied onto another system with which it cannot communicate directly. By comparing this code against existing codes stored locally at different locations, we can verify who has access granted them while preventing others from accessing those systems.

Problems solved by technology

The technical problem addressed in this patented text relating to improving trustworthiness during legal transactions related to certifications or loans made through traditional methods such as paper checks with no means to prevent forgery. Current systems rely heavily on human judgement and are prone to errors due to subjective factors like fatigue overlooking outdated documentation that may have been used without permission beforehand.

Abstract

The invention discloses a user affiliation verification method and device based on a group signature, computer equipment and a storage medium. The method comprises the steps of receiving an affiliation verification application encrypted by a first private key and sent by a user terminal; decrypting the affiliation verification application by using a first public key corresponding to the first private key, thereby obtaining the user signature and terminal information of an affiliation party corresponding to the user; sending a group signature obtaining requirement to a terminal of a home party;receiving a group signature sent by a terminal of a home party, and decrypting the group signature by using a second public key corresponding to the second private key to obtain a group signature plaintext; judging whether the group signature plaintext is matched with the user signature or not; and if the group signature plaintext is matched with the user signature, judging that the user belongsto the home party. Therefore, accurate and automatic affiliation verification is realized.
