The invention discloses a zero-knowledge proof method, system, and storage medium for medical documents. The method includes: a third-party terminal sends an acquisition request to a medical institution server, and the medical institution server sends medical data documents and medical data that meet the conditions according to the acquisition request. The Merkel verification information corresponding to the document, the authoritative organization ID to the third-party terminal, the third-party terminal according to the medical data document, the Merkel verification information corresponding to the medical data document, the hash algorithm corresponding to the authoritative institution ID, and the ordered Merkle Tree construction rules are used to calculate, obtain the Merkle root value to be verified corresponding to each medical data document, and judge whether each Merkle root value to be verified is valid according to the Merkle root value to be verified, the authority ID and the blockchain platform , verifying the medical data document according to the judgment result. The invention solves the technical problem that it is difficult to check the authenticity of medical data.
Description
technical field [0001] The present invention relates to the technical field of blockchain platform, in particular to a zero-knowledge proof method, system and computer-readable storage medium for medical documents. Background technique [0002] In recent years, with the rapid development of the Internet and storage technology, an era of big data and artificial intelligence has gradually entered every aspect of our lives. However, during the transmission process, data is often stolen or tampered with. For scientific research institutions, insurance institutions or other institutions that need to obtain a large amount of medical data, the reliability of medical data is high, and it is necessary to ensure the authenticity of the obtained medical data. sex. However, these institutions often have difficulty in checking the authenticity of the obtained medical data or do not have the ability to check. [0003] The above content is only used to assist in understanding the technic...
