Open source of blockchain electronic evidence storage platform
since 2018, with the establishment of the Internet court and the development of electronic evidence platform institutions following the development of blockchain technology, and with the development and improvement of alliance chain technology, some innovative electronic evidence platform enterprises have taken the lead in applying blockchain technology to the field of electronic evidence, such as blockchain electronic evidence platforms such as easy security
easy preservation has been included in the "typical cases of blockchain electronic evidence platform" by the supreme law research group, which indicates that the blockchain technology and access evidence of easy preservation are widely recognized by the judiciary. Before that, easy security has been included in the "typical cases of blockchain intellectual property rights" by the Inner Mongolia high court and Wuxi intermediate people's court, selected in the "typical cases of blockchain platform" by the law experts' lecture hall, and selected in the "2020 China blockchain enterprise investment map" by the China business intelligence network, and its actual qualification has been recognized
blockchain electronic evidence is by no means a simple legal logic and theoretical framework of "using blockchain technology is blockchain electronic evidence". Only by using blockchain technology to ensure the authenticity, legitimacy and relevance of electronic evidence before, ring and after the chain, can we ensure the conversion of ordinary electronic data into judicial credible blockchain electronic evidence
at the technical level, blockchain, CA, time stamp, encryption algorithm and other technologies are used to authenticate the real name of platform users, and block chain store the user's signed data, so as to form a full evidence chain recording the key details of the whole process, and generate tamperable hash encrypted files, so as to ensure the authenticity and reliability of the data before being chained and the integrity of the data when being chained
after being linked, easy security stores relevant data synchronously on the servers of notary office, Arbitration Commission, Internet court, right protection center, judicial appraisal institute and other institutions through the open platform of security chain; It can also conct visual blockchain inspection on the official websites of notary office, Arbitration Commission, judicial appraisal institute, Capital Intellectual Property Association, etc. Ensure that the whole process can be traced, the whole data can be verified, and the whole link can be trusted.
Yibao block chain technology is based on bcos open source platform, which can calculate metadata through sha-512 hash algorithm, timestamp service and pbft consensus algorithm, and flexibly expand alliance chain institutions and nodes. The data stored in the blockchain through easy preservation will be stored on the blockchain in the form of hash value. With the characteristics of decentralized and distributed storage in the blockchain, the authenticity and objectivity of the data can be effectively guaranteed, and tampering can be effectively prevented
however, in view of the characteristics of electronic data, such as reprocible, easy to tamper, difficult to confirm, difficult to provide evidence and so on, electronic evidence urgently needs a professional, reliable and judicial credible technology to effectively solve the trust problem of electronic evidence
blockchain has the advantages of decentralization, distributed accounting, encryption and traceability, which can ensure the integrity and authenticity of data on the chain. Once it is tampered or forged, it can be found. At the same time, because the blockchain has the characteristics of Distributed Accounting, even if the data on indivial nodes are deleted, other nodes can still save the data completely, ensuring the normal operation of the whole blockchain storage system
in 2018, the supreme law of the people's Republic of China clearly pointed out in the provisions on Several Issues concerning the trial of cases by Internet courts that the electronic data submitted by the parties can be verified by electronic signature, trusted time stamp, hash value verification, blockchain and other technical means of evidence collection, fixation and tamper proof, or by electronic forensics storage platform authentication, The Internet court should confirm. This is the first time that the legal effect of blockchain technology in electronic data is affirmed from the judicial level
based on the above advantages, blockchain is naturally suitable for electronic data storage. The introction of blockchain can effectively solve the authenticity and legitimacy of electronic evidence and make the process of electronic data storage more reliable. By using blockchain technology, easyprotection can solve the whole link trustworthiness problems of electronic data, such as generation, certificate storage, notarization and evidence proof; After being linked, each judicial node in the security chain is used to ensure the credibility and security of the data; In litigation, evidence goes directly to the Internet court to improve the efficiency of rights protection.
In order to meet the growing demand for litigation services of the people in the process of regional collaborative development between Sichuan and Chongqing, our blockchain certificate keeping technology will play a series of roles such as certificate keeping, authentication and evidence collection in cross domain case filing, petition joint control, online litigation, joint conference and other cooperation between Sichuan and Chongqing, making long-distance and contactless cooperation more standardized, convenient and efficient. To provide assistance for Sichuan Chongqing high court to achieve inclusive, equal, convenient, efficient, intelligent and accurate litigation services
this paper briefly introces the application of blockchain evidence storage -- "real hammer" trusted electronic evidence platform
Real hammer "trusted electronic evidence platform, through cooperation with forensic authentication institutions, notary offices, arbitration institutions, Internet courts, etc., realizes the storage, retrieval and issuance of evidence on the chain, and reces the cost of electronic data evidence preservation, It is convenient for electronic data collection and evidence identification, and improves the litigation efficiency in the field of judicial evidence preservation
at present, the evidence traceability mode of "real hammer" trusted electronic evidence platform has been recognized by many courts in Beijing, Xiamen, Guangzhou and Shenzhen, and some banks and state-owned enterprises have begun to use "real hammer" trusted electronic evidence platform
We mainly apply blockchain technology to the field of electronic data distributed storage, including contract storage, e-mail storage, file storage, structured data storage, etc
the specific forms of electronic evidence in judicial practice are becoming more and more diversified, and the frequency and amount of electronic data are increasing significantly. Different types of electronic evidence have different forms of formation, but they are easy to die out, easy to tamper with, and highly dependent on technology. Compared with traditional physical evidence, it is more difficult to determine the authenticity, legitimacy, and relevance of electronic evidence through judicial review
in the whole life cycle of the generation, collection, transmission and storage of electronic data, blockchain technology can be used to protect electronic data, prevent tampering, and leave traces of data operation, so as to provide effective means for relevant institutions to review. Using blockchain technology to preserve electronic evidence, the electronic data that needs to be preserved is recorded in the form of transaction, stamped with time stamp, and recorded in the block, so as to complete the process of data preservation and preservation. In the process of data storage, multiple participant nodes witness together and maintain a distributed ledger, which greatly reces the possibility of data loss, tampering and attack. The combination of blockchain and electronic data storage can rece the cost of electronic data storage, facilitate electronic data collection and evidence identification, and improve the litigation efficiency in the field of judicial storage
The unique characteristics of blockchain technology, such as non tampering, non repudiation and multi-party participation, are naturally consistent with the requirements of electronic data storage. Electronic data storage is an important application field of potential blockchain technology
in the face of the growing demand for electronic data, the traditional way of certificate keeping graally shows some shortcomings, such as high cost, low efficiency and difficulty in obtaining information. In addition, in judicial practice, the parties generally lack the ability to adce evidence, the quality of electronic evidence submitted to the court is poor, there are a large number of improper evidence collection proceres, incomplete evidence, poor directivity to the facts of the case and other problems, which directly affect the proportion of electronic evidence in litigation
the combination of blockchain and electronic data storage can rece the cost of electronic data storage, facilitate the evidence identification of electronic data, and improve the litigation efficiency in the field of judicial storage
therefore, we have been committed to integrating blockchain technology into procts to provide users with financial level security: for example, through the joint establishment of a judicial deposit chain with multiple parties (including forensic identification center), we can realize the permanent solidification and preservation of decentralized evidence, and simplify the process of traditional evidence collection and issuance. That is to use the distributed blockchain storage technology to ensure that the contract evidence is not tampered
Taking the micro right of the blockchain intellectual property protection platform of e-baoquan as an example, its forensics technology has the invention patent certificate issued by the State Intellectual Property Office. When users collect evidence through the Internet, they will automatically obtain the current standard time, and calculate the hash digest value of the forensics file according to the standard time, Then the hash summary value and forensics file are uploaded to the Security Center for blockchain preservation, which makes the evidence chain more complete
at the same time, different from other ways of evidence collection, micro right and notary office jointly develop "forensics guarantee v2.0", and have relevant soft work certificates, which ensure that the whole process of evidence collection is carried out under the supervision and operation of notary office, and ensure the cleanness of forensics environment and objectivity of evidence collection. Forensic methods include: Web forensics, screenshot forensics, screen recording forensics and video forensics. Users can choose the forensics methods according to their needs, and complete the forensics in a few seconds at the fastest. They can also apply for the issuance of notarial certificate and notarial custody letter online
Blockchain has the characteristics of decentralization, distributed storage, encryption algorithm, non tampering, traceability and so on. It has natural technical advantages in electronic data storage, and can well solve the problems of traditional storage methods, such as easy to lose and be tampered with
take the micro right of the blockchain intellectual property protection platform of yibaoquan as an example, the micro right encrypts the metadata through sha-512 hash algorithm, time stamp service and pbft consensus algorithm, and stores the electronic data on the blockchain in the form of hash, and then synchronously stores the electronic data to the notary office, judicial identification center, judicial identification center, and other departments through the security chain open platform On the Internet court, Arbitration Commission, right protection center, CA institutions and other nodes, through the decentralized and distributed storage of blockchain, the originality and non tamperability of electronic evidence can be effectively guaranteed
