Blockchain archives evidence chain
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
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
Taking micro right as an example, the evidence of micro right goes directly to the Internet court. When a user files a case in the Guangzhou Internet court, he can directly extract the files stored in the micro right according to the evidence number, and automatically perform hash check to ensure that the files have not been tampered with, and take the proof evidence of micro right as credible evidence
all data stored through micro right can be issued with a relevant certificate. Users can easily view the relevant information of electronic evidence by opening wechat to scan the QR code on the certificate, and directly present evidence in court
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
