Abstract

One or more embodiments of the invention provide a block chain-based message verification method and device. The method comprises the steps of determining a private chain message node corresponding to a target message in a pre-established message block private chain; performing Hash encryption on the node information of the private chain message node to obtain a Hash value of the private chain message node; acquiring a public chain block Hash value from a private chain block where the private chain message node is located; acquiring a Hash ciphertext in a public chain message node corresponding to the target message from a pre-established message block public chain according to a message number corresponding to the target message in the node information and the public chain block Hash value; and in response to determining that the Hash value of the private chain message node is the same as the Hash ciphertext, outputting a signal indicating that the target message is successfully verified. According to the invention, different block chains are respectively designed at the server side and the client side, so that the verification function of the communication information is realized on the basis of ensuring the privacy of the communication information.

Description

technical field [0001] One or more embodiments of this specification relate to the technical field of blockchain, and in particular to a method and device for message verification based on blockchain. Background technique [0002] The instant messaging system based on the mobile terminal has become an important communication tool for people. At present, with the development of communication technology and mobile terminal technology, out of cost and efficiency considerations, people start to use mobile instant messaging systems for communication in more and more fields, and these fields put forward new requirements for instant messaging systems. [0003] In addition to higher requirements for traditional features such as the confidentiality and non-tampering of communication information, users also require that communication information cannot be known by third parties (including servers). On the other hand, when disputes arise, users hope that the sent Information is verifi...
