A blockchain-based information validity detection method and device

Abstract

The present application provides a block chain-based information validity detection method and device, wherein the method includes: obtaining the data uploaded by the publisher on the current block node, and substituting the preset unified rules of the block chain, Collect and obtain the current data hash value; the current block node signs the current data hash value to obtain the current signature; the current block node encrypts the current data hash value to obtain the current encrypted information; the current block node according to the Merkle Tree data The storage structure stores the current encrypted information and the current signature in the block to obtain the current information; broadcasts the current information and synchronizes it to other block nodes; any adjacent trusted block node of the current block node receives the current block node Broadcast the current information, and check the validity of the information according to the storage structure of the current information. The detection method and device provided by this application can effectively solve the problem that the existing data is easily tampered and the validity cannot be guaranteed.

Description

technical field [0001] The present application relates to the technical field of information security, in particular to a block chain-based information validity detection method and device. Background technique [0002] The Internet is a new way of information dissemination, which relies on the TCP / IP protocol (network communication protocol), and the bottom layer does not care about the difference between the data transmitted above - for all intermediate dependent hardware devices (including routers, switches, etc. ), all data is 0 or 1. This indiscriminate transmission creates a high-speed channel for information duplication and widespread dissemination, creating the current era of information explosion. Although the Internet solves the problem of how to disseminate information quickly, it also brings new problems of information attribution. For example, we can browse any article on the Internet or watch any video downloaded from the Internet, but we have no way of knowin...
