AI Technical Summary
In the field of artificial intelligence, how to improve the security of personal knowledge base (PKB) data, protect user privacy, prevent data leakage, unauthorized access, model inversion attacks, data association risks, and intellectual property risks are all important considerations.
By determining the deployment location and access rule level of the target model, and combining user and device rules, the target level of access requests is dynamically evaluated, and access permissions are determined based on the model deployment location, thus achieving flexible data access control.
It improves the security and privacy of data access, reduces the probability of access from untrusted location models, and enhances the flexibility and real-time response capability of data protection.
