AI Technical Summary
Existing technologies suffer from privacy leaks, computational distortions, and lack of incentives in secure cross-organizational data exchange. In particular, in federated learning frameworks, the central server's observable gradient vectors lead to privacy leaks, the lack of gradient verification mechanisms causes computational distortions, and the participants lack economic incentives.
By employing a privacy-based computation approach, and through a two-layer interaction between coordinated contracts and local smart contracts, this approach utilizes interval proofs, encrypted Bloom strings, homomorphic logic AND operations, zero-knowledge proofs, and blockchain technology to achieve traceability of data sources, sample alignment, verifiable computation, and economic incentive mechanisms, thereby ensuring the privacy and compliance of the data security exchange process.
It achieves privacy protection, computational accuracy, and participant incentives in the cross-organizational data exchange process. Through blockchain notarization, automatic execution of smart contracts, and encryption technology, it ensures the auditability and security of the data exchange process, avoids privacy leaks and computational distortion, and provides an economic incentive mechanism.
