The invention discloses a method for verifying detection data source data provenance based on a blockchain technology, which comprises the following steps: first, serializing data and storing the serialized detection data in a data blockchain; then, operating the detection data via detecting personnel, generating a test report, and providing a data label; next, determining the authenticity and validity of the data according to the data status and data position recorded by the data label and the log blockchain; finally, obtaining the detailed information of the data in the blockchain through adata link in the data label, calculating a hash value, and judging whether the data are tampered with according to the hash value. Through the decentralization feature of the blockchain technology, the problem of weak data disaster tolerance is solved; and through data verification, it is quickly verified whether the data are tampered with, thereby solving the problem of data security.
Description
technical field [0001] The invention relates to the technical field of data traceability, in particular to a detection data traceability verification method based on block chain technology. Background technique [0002] Blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is a non-tamperable and unforgeable distributed ledger guaranteed by cryptography. It has the characteristics of decentralization, Features such as openness, autonomy, and non-tamperable information. [0003] In order to ensure the authenticity and traceability of the test data, traditional engineering testing requires the retention of original paper record data, and the paper data cannot be altered, but can only be altered and signed. The detection data is only stored in a single node, the security and disaster recovery capabilities are not strong, and it is not easy to restore the data after it is damaged. The validity of the data is also jud...
