Abstract

The embodiment of the invention provides a file circulation method and a file circulation system based on a block chain, and a device. The method comprises the steps of according to a block in a blockchain, acquiring first summary information, a storage position of a file to be verified and a ciphertext of a symmetric key; decrypting the storage position of the file to be verified and the ciphertext of the symmetric key according to a personal private key, and thus acquiring the storage position of the file to be verified and the symmetric key; acquiring the file to be verified according to the storage position of the file to be verified, decrypting the file to be verified according to the symmetric key, and acquiring second summary information according to a summary algorithm and the decrypted file to be verified; comparing the first summary information with the second summary information, and acquiring a verification result of the file to be verified according to a comparison result; and if the verification result is that verification is successful, receiving the file to be verified. According to the file circulation method and system based on block chain and the device providedby the embodiment of the invention, the file cross-domain circulation efficiency can be improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technology, and in particular to a block chain-based file transfer method, device and system. Background technique [0002] With the wave of information development, digital office has become the most basic IT means for governments, enterprises and institutions. In the construction of smart IT information such as smart cities and e-government affairs, a large amount of electronic data transmission is generated between the government and enterprises and institutions, and it is necessary to open up data sharing between enterprises and institutions, between government departments, and between governments and enterprises and institutions link to realize cross-domain file transfer. [0003] For example, there are often official business exchanges between enterprise A and the court. Enterprise A usually submits electronic materials to the court once a month, and the court takes a perio...
