Abstract

The invention discloses a method for determining data integrity, a related device and a data integrity protection system, and relates to the technical field of computers. A specific embodiment of the method comprises the steps of generating an abstract for data sent by a data sending device to obtain a first data abstract, and storing the first data abstract in a block chain; generating an abstract for the data received by a data receiving device to obtain a second data abstract; and querying a first data abstract corresponding to the data received by the data receiving device from the block chain, and checking the second data abstract by using the queried first data abstract to determine the integrity of the data received by the data receiving device. According to the implementation mode, the integrity of the data can be guaranteed, the implementation complexity is reduced, the efficiency is improved, safer and more convenient data integrity protection is realized, the time cost is low, and the on-chain data volume is small.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method for determining data integrity, a related device and a data integrity protection system. Background technique [0002] In the field of data security, the confidentiality and integrity of data transmission are the main purposes of data security transmission. Among them, the data integrity protection function can identify the behavior of data tampering, so as to ensure that the data cannot be tampered with. In the existing data integrity solutions, the data sender generally calculates the hash value of the data, puts it behind the data and sends it to the data receiver, and the receiver calculates the hash value of the received data by itself, and compares it with The hash value sent by the transmitting party is compared to determine whether the data has been tampered with during transmission. During the transmission process, in order to ensure that the hash value will...
