Embodiment Construction

[0045] The technical solutions in the embodiments of the present invention will be described clearly and in detail below with reference to the drawings in the embodiments of the present invention. The described embodiments are only some of the embodiments of the invention.

[0046] The technical scheme that the present invention solves the problems of the technologies described above is:

[0047]The user performs identity authentication through the client. After the identity authentication is passed, the client generates an identity-based blockchain address as the blockchain address for calling and deploying smart contracts.

[0048] Such as figure 2 As shown, the flow chart of the certificate depositor logging in to the client to deposit certificates through the smart contract is as follows:

[0049] The depositor logs in to the client, loads the blockchain address of the depositor, submits the evidence data and library key, and the server stores the deposit data in a thir...

Abstract

The invention requests to protect an electronic evidence storage method based on a block chain smart contract, and the method comprises the steps: carrying out the evidence storage through the smart contract by a evidence storage person, carrying out the query of evidence information through the smart contract by a verification person, carrying out the evidence downloading through the smart contract by a researcher, and carrying out the uploading of an evidence analysis result through the smart contract. The smart contract is a key logic module for realizing the method and exchanges data withthe block chain, so that the integrity, the verifiability and the tamper resistance of the electronic evidence are ensured. And meanwhile, all data operations are recorded on the block chain, so thatthe traceability of the electronic evidence is realized.

Description

technical field [0001] The invention belongs to the technical field of block chains, and in particular relates to an electronic evidence storage method based on block chain smart contracts. Background technique [0002] With the rapid development of the Internet and electronic information technology, the amount of electronic data based on computers and computer networks has exploded. The emergence of new things such as electronic contracts and online transactions has brought new potential disputes, so specific and valid electronic data plays an increasingly important role in the process of proving the facts of a case. [0003] The preservation of electronic evidence is to avoid the loss of electronic evidence or the situation that it will be difficult to obtain in the future. Electronic evidence is preserved through various technical means and managed in the correct way, so that it is convenient for prosecutors or research analysts to analyze, check, and prove that the Proo...
