Embodiment

[0023] Such as figure 1 A proof-fixed verification method after a multi-party consensus signature is shown, including the following steps,

[0024] Step 1: data encryption and hash calculation, multiple sets of original data are respectively processed by encryption algorithm, hash is calculated for multiple sets of original data processed by encryption algorithm, and the calculated hash waits for the next step of processing;

[0025] Step 2: Multi-signature evidence fixed platform processing, the hash calculated in step 1 is sent to the multi-signature evidence fixed platform, and the multi-signature evidence fixed platform is used for processing, including determining the consensus algorithm, determining the blockchain network, and blockchain The network sends the hash to the notary office node, the arbitration commission node, the court node, and other institutional nodes, waiting for the next step of processing;

[0026] Step 3: Node consensus, distribute the hash in step ...

Abstract

The invention discloses an evidence fixed verification method after multi-party consensus signature. The method comprises the steps of data encryption and hash calculation, multi-party signature evidence fixed platform processing and node consensus. The method comprises the following steps: firstly, processing a plurality of groups of original data encryption algorithms and then calculating hash;sending hash obtained through calculation to a multi-party signature evidence fixing platform, determining a consensus algorithm, determining a block chain network and determining a block chain in sequence, enabling the corresponding block chain to send the Hash to a notarization office node, a arbitration commission node, a court node and other institution nodes; allowing the notarization officenode, the arbitration Commission node, the court node and the other institution nodes to carry out identity confirmation, hash verification, consensus processing, signature processing and chaining fixing on hash in sequence. According to the evidence fixed verification method after multi-party consensus signature, intervention of a third party is guaranteed, the trust degree in the block chain isalso increased, and the method has the advantages of being high in trust degree and safety.

Description

technical field [0001] The invention relates to an evidence fixed verification method, in particular to an evidence fixed verification method after a multi-party consensus signature. Background technique [0002] Existing platforms use their own credit or authority as an endorsement to provide services such as solidification and verification of electronic evidence. However, driven by interests and other factors, the electronic data in the centralized storage or single-signature blockchain storage mode may be tampered with or deleted, and there is a possibility that the judicial effect of electronic data is not strong and may not be recognized by the judiciary. [0003] Therefore, there is a need for a multi-party consensus signed evidence fixation device for storage, and multi-party intervention to ensure the validity of the evidence fixation. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a verification method...
