AI Technical Summary

Technical Problem

Existing technologies for deleting multiple copies of personal information suffer from communication failures that cause some platforms to fail to delete copies in a timely manner, leading to information leakage and illegal use. Furthermore, existing solutions increase system complexity and implementation costs.

Method used

By circulating copies of personal information between information domains and signing and verifying them based on the personal information subject identifier, combined with storage, circulation, access, and deletion protocols, the timely deletion and irreversibility of all copies are ensured.

Benefits of technology

It enables comprehensive deletion of personal information, ensuring that the information cannot be recovered, reducing system complexity and dependence on third parties, and protecting the data subject's right to delete and intellectual property rights.

Abstract

The present application relates to a kind of efficient safe personal information multiple copy deletion method and system, the method includes: personal information is signed with personal information subject identifier and is uploaded to information field, and is stored as personal information copy by information field;Personal information copy circulates between information field, and each personal information copy records its source and destination;When information field receives delete command, delete command is communicated to each information field based on personal information subject identifier and the destination information in personal information copy, and delete operation is executed;Information field completes deletion and stores the log of self domain identifier and the feedback information received, and the log is fed back to the upper level information field;Information field completes deletion and stores the log of self domain identifier and the feedback information received, and the log is fed back to the upper level information field;The system includes several information fields capable of executing the above-mentioned operation, to realize personal information multiple copy associated storage, associated deletion and associated deletion verification.
