Abstract

The invention provides a file verification method, a file verification system and a file verification server. The file verification method includes the following steps of establishing a tree-type datastructure according to the plurality of first hash values of a plurality of first electronic files; storing the first root hash values of the tree-type data structure into a block of a block chain; for one of the first electronic files, generating verification data including one of block information of the block, a first hash value and at least one first non-terminal hash value of the tree data structure; abd verifying the second electronic file according to the verification data.

Description

technical field [0001] The present invention relates to a file verification method, in particular to a file verification method applying block chain technology, a file verification system and a file verification server. Background technique [0002] Electronic files have the risk of being easily tampered with and deleted without being detected. Therefore, there is currently an idea of ​​storing electronic files in a block chain (block chain) to ensure that the data will not be tampered with. Blockchain technology is composed of cryptography, mathematics, algorithms, and economic models. It combines point-to-point network relationships and adopts distributed consensus algorithms to solve the synchronization problem of traditional distributed databases. It is a major breakthrough in modern integration of cross-field technologies. The information recorded in the blockchain is not easy to forge and cannot be tampered with. [0003] However, the block storage space for each blo...
