BLOCKCHAIN-BASED DATA PROCESSING METHOD AND APPARATUS, ELECTRONIC DEVICE, COMPUTER-READABLE STORAGE MEDIUM, AND COMPUTER PROGRAM PRODUCT

WIPO Patent Application WO/2024/078108

A1

Disclosed in the embodiments of the present application are a blockchain-based data processing method and apparatus, an electronic device, a computer-readable storage medium, and a computer program product. The method comprises: a first device generating a first bit array corresponding to first service data, and encrypting the first bit array by means of a data key, so as to obtain a ciphertext bit array, wherein the data key is generated by a second device in a data intersection application, and the data intersection application runs in a trusted execution environment a; transmitting the ciphertext bit array to a blockchain node, such that the blockchain node forwards the ciphertext bit array to the second device; in the data intersection application, the second device decrypting the ciphertext bit array by means of the data key, so as to obtain the first bit array; the second device generating a second bit array corresponding to second service data; and the second device determining service intersection data between the first service data and the second service data, and performing service processing associated with the service intersection data.
