Abstract

The invention discloses a block chain-based criminal case evidence management method and device and a medium. The method comprises the steps of establishing a block chain for storing evidence information, service nodes in the block chain comprising a public security bureau, a checkout center and a court, and a plurality of case filing nodes for consensus existing on the service nodes; receiving case filing information of a case filing node, and marking the case filing node as a first node, the case filing information comprising criminal case evidences; determining the case filing nodes participating in consensus according to the case filing information; and after consensus is reached, packaging the case evidences into blocks and writing the blocks into the block chain. A new consensus mechanism is used. A plurality of case filing nodes used for consensus are set for each public security law mechanism. The corresponding case filing nodes are selected according to the correlation of cases. The public and transparent characteristics of the block chain are utilized, so that personnel of the public security law mechanisms can be prevented from being suspected, case related personnel canbe prevented from being hooked with each other, and the credibility of chained evidences is effectively improved.

Description

technical field [0001] This application relates to the technical field of evidence management, and in particular to a blockchain-based criminal case evidence management method, device and medium. Background technique [0002] Criminal cases are public prosecution cases, which have a relatively large impact on society and are likely to cause extensive discussion in society. In litigation, evidence is the core content, and the authenticity of evidence comes from the investigation and evidence collection at the source, as well as from the storage and transfer in the middle. Evidence has the potential to be tampered with, either at the source or on the way. Contents of the invention [0003] The embodiment of this specification provides a blockchain-based formal case evidence management method, equipment, and media, which are used to solve the following technical problems in the prior art: before the evidence is written into the blockchain, there is a possibility of tampering...
