Embodiment 1

[0069] Example 1: Electronic data as electronic evidence

[0070] Electronic evidence is mainly used in the judicial industry. Through the electronic evidence storage system, operations such as storage, extraction, and presentation of electronic evidence can be realized, corresponding to the processes of depositing, obtaining evidence, and demonstrating evidence in judicial practice, such as Figure 4 shown.

[0071] 1) Generation of electronic deposit certificate

[0072] After the procuratorate, government agencies and other relevant institutions complete the registration on the blockchain electronic deposit system, they can operate the electronic evidence on the chain. After the electronic evidence is uploaded to the chain, the system will generate the corresponding electronic deposit certificate. Electronic evidence supports various types of data such as pictures, audio recordings, video recordings, and contract documents.

[0073] 2) Notarization of electronic evidence...

Embodiment 2

[0081] Embodiment 2: Electronic data is an electronic protocol

[0082] Electronic agreements can be applied to the signing of agreements and contracts.

[0083] Participants first complete the registration on the blockchain electronic certificate deposit system. After successful registration, they can obtain the functions of electronic agreement signing on the chain, electronic certificate deposit notarization and electronic agreement execution.

[0084] The system provides the electronic agreement to complete the uploading of the electronic agreement by filling in the template, signing and uploading or self-signing and uploading, and generating a blockchain electronic certificate. The data on the chain records the original data of the electronic data and the specific content of the electronic agreement. Through cooperation with government agencies, judicial authentication institutions, and notary institutions, the notarization of electronic deposit certificates can be compl...

Embodiment 3

[0085] Example 3: Electronic data is electronic proof

[0086] By cooperating with government agencies, notary offices and judicial appraisal institutions, the blockchain electronic deposit system introduces relevant data interfaces, calls public security, local taxation, education and other government department data, and realizes the proof of kinship, education, salary income, marital status, etc. Business is handled online.

[0087] When issuing electronic certificates, government agencies, notaries and judicial appraisal institutions first log in to the blockchain system, search for electronic data information on the blockchain, and then generate electronic deposit certificates for the required electronic certificates under the requirements of laws, regulations and industry norms . When the certificate is received, the certificate receiver can query the corresponding electronic certificate information on the blockchain electronic certificate system to complete the certifi...

Abstract

The invention discloses an electronic evidence storage method and system based on a block chain. The method comprises the steps that an electronic evidence is generated, and a user uploads electronicdata to a blockchain electronic evidence storage system; the block chain electronic evidence storage system encrypts the electronic data and stores the electronic data on a block chain; meanwhile, according to abstract information in the electronic data, a corresponding electronic evidence is generated; and association between the electronic evidence and the electronic data is established. The system comprises a data uploading module, an encryption storage module, an electronic evidence generation module and an association relationship module. the problem that electronic data is easy to lose and tamper in the prior art is solved, the uplink data cannot be tampered and stored in an encrypted mode, data storage safety is guaranteed, and high availability and traceability are achieved. By means of the block chain programmable intelligent contract technology, under the condition that conditions are met, a related electronic protocol can be executed through an intelligent contract, and theexecution cost of the protocol is reduced.

Description

technical field [0001] This application relates to the technical field of block chains, in particular, to a method and system for electronic certificate storage based on block chains. Background technique [0002] At present, with the development of computer technology and the popularization of the Internet, all kinds of traditional paper documents are gradually becoming electronic. Electronic data is easy to store, easy to carry, and low storage cost, which brings great convenience to various business activities. However, electronic data also has its limitations, such as easy loss and tampering. For some documents with high security requirements, such as document evidence, contracts, agreements, and citizen personal information document certification, the existing technology cannot fully meet the requirements. [0003] Aiming at the problem that electronic data is easy to be lost and tampered with in related technologies, no effective solution has been proposed so far. ...
