Blockchain strategy verification
Through the record number on the forensics certificate, you can also directly query the blockchain on the official websites of easy security, notary office and Arbitration Commission, including the preservation subject, preservation timestamp, Guangzhou Internet court evidence number, blockchain hash value and other relevant information, so as to ensure the openness, transparency and traceability of blockchain storage data
Article 5 of the provisions on collection, extraction, examination and judgment of electronic data in handling criminal cases stipulates that the integrity of electronic data can be protected by calculating the integrity check value of electronic data
to verify the integrity of electronic data, hash value and other verification algorithms are generally used
micro right encrypts the original data through sha-512 hash algorithm, time stamp service and pbft consensus algorithm, generates a unique corresponding digital fingerprint for the subject, time, process and content of the certificate, and encrypts and stores it on the blockchain to effectively guarantee the integrity of the certificate data
users can input the record number of the stored data and upload the original file through the "verification preservation" on the official website of the micro right. The system automatically compares the hash value of the uploaded file with the hash value of the original stored data. If the stored data and the uploaded file are complete, they pass the verification, otherwise, they fail< br />
