AI Technical Summary
Existing technologies cannot achieve end-to-end encrypted computation of data, cannot guarantee the confidentiality and integrity of the original data, increase the risk of leakage, cannot achieve fine-grained dynamic control of subjects, resources, operations and environment, cannot support standard and custom policies, and are difficult to support the privacy protection and compliant use of data in multiple scenarios. At the same time, they cannot achieve joint proof of the validity of computation results and context, cannot rely on trusted settings and key isolation to ensure security, and are difficult to support the privacy protection and compliance requirements in multi-tasking and high-concurrency scenarios.
A privacy protection platform for blockchain smart contracts is designed, comprising a data access module, a privacy computation execution module, a privacy policy control module, and a zero-knowledge proof generation and verification module. The data access module collects and processes raw data; the privacy computation execution module performs encrypted computations in a cryptographic environment; the privacy policy control module supports standard and custom policy languages; and the zero-knowledge proof generation and verification module generates and verifies the proof circuits for the computation tasks.
It achieves end-to-end encrypted computation, ensuring the confidentiality and integrity of the original data. It supports complex calculations without exposing plaintext, reducing the risk of leakage. It enables fine-grained dynamic control of subjects, resources, operations, and environment. It supports standard and custom strategies, improves the ability to jointly prove the validity of computation results and context, enhances the security and credibility of the system, and is suitable for privacy protection and compliance requirements in multi-tasking and high-concurrency scenarios.
