Abstract: Blockchain technology, as a popular technology at present, is practiced in various fields due to its characteristics of non-tampering, traceability, and decentralization. However, in the process of implementing the blockchain system, how to ensure that the file content is not falsified for the file data uploaded to the blockchain system becomes a key issue that restricts the development of the blockchain system. The traditional file security verification method mainly performs hash operations on user files and obtains corresponding hash values. However, in this process, the calculated hash values cannot be guaranteed to be modified. This paper proposes a file security verification method based on blockchain technology, and verifies the feasibility of the method through experiments.
Keywords: Blockchain Technique, Hash-operation, Not-tamperable
