AI Technical Summary

Technical Problem

Existing technologies lack a unified rights confirmation mechanism and trusted computing support in cross-institutional data element circulation scenarios, resulting in ambiguous ownership determination, plaintext leakage of sensitive data, untraceable calculation processes, and difficulty in verifying tampering. Furthermore, the lack of cross-domain collaborative rights confirmation capabilities reduces the willingness of data holders to share data and restricts the safe and efficient circulation and value release of data elements.

Method used

By employing multidimensional feature mapping and homomorphic encryption preprocessing of sensitive fields, a Merkle tree of data ownership is constructed and a dynamic sequence of ownership certificates is generated. Combined with distributed encrypted aggregation operation and blockchain consensus mechanism, the end-to-end encrypted secure computation and ownership traceability of data elements are realized.

Benefits of technology

It enables full-process traceability of data element ownership, full-process secure computation, reliable and verifiable computation process, and automatic quantification of data contribution, thereby improving the security, controllability, and fairness of value distribution in cross-domain data element circulation.

Abstract

This invention provides a blockchain-based method and system for calculating and integrating data element circulation rights confirmation, relating to the field of data processing technology. The method includes: acquiring the original data elements to be circulated; performing multi-dimensional feature mapping and homomorphic encryption preprocessing on the original data elements to obtain standardized data element descriptors; constructing a Merkle tree of data ownership based on the standardized data element descriptors; performing asymmetric encryption signature on the root node hash value of the Merkle tree to obtain an initial rights confirmation certificate; associating the on-chain transaction hash of the initial rights confirmation certificate with the standardized data element descriptors to obtain a dynamic rights confirmation certificate sequence; retrieving a matching target rights confirmation certificate from the dynamic rights confirmation certificate sequence; and obtaining an execution constraint strategy set containing calculation boundary thresholds and data flow tracking strategies based on the target rights confirmation certificate. This invention improves the security, controllability, and efficiency of data element circulation.
