Electronic evidence of blockchain deposit

1. In 2020, with the promotion of online litigation mechanism and the promotion of the application of blockchain electronic evidence by Internet courts, the number of cases involving blockchain electronic evidence will increase significantly. First line Internet companies and leading enterprises in various instries generally use blockchain electronic evidence service in daily legal work because of their sensitivity to new technologies. The Supreme People's court has set up 14 major topics, among which the research group of "Research on electronic litigation rules in the Internet Era" focuses on "basic principles of electronic litigation; The conditions, scope and methods of online case filing, online court hearing and electronic service; In order to provide suggestions for the supreme legal system to formulate judicial policy and issue judicial interpretation, we should study and form a complete and systematic draft of electronic litigation rules
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.

2.

In Internet cases, electronic evidence has become a difficult problem in Internet trials because it is difficult to store evidence, collect evidence and notarize. By using blockchain technology, easyprovision can solve the whole link trustworthiness problems of electronic evidence, such as generation, storage, notarization and evidence proof; After being linked, each judicial node in the security chain is used to ensure the data's trustworthiness and security; In litigation, evidence goes directly to the Internet court to improve the efficiency of rights protection

easy preservation since 2014, we have been deeply engaged in the R & D and application innovation of the underlying technology of blockchain . By expanding the judicial service channels, we have successfully taken the notary office, judicial authentication center, Internet court, Arbitration Commission, right protection center and other authoritative institutions as the important nodes of the preservation chain, so that electronic data can be saved from the aspects of generation, certificate storage, right protection To the final use, the relevant judicial institutions do synchronous supervision and notarization to enhance the credibility of the blockchain certificate data

3. More and more enterprises join the team of digital transformation, how to effectively protect data security will become the core competitiveness of this era. In 2012, the newly revised "Civil Procere Law" and "Criminal Procere Law" officially included electronic data in the legal classification of evidence, the relevant laws and regulations of electronic data began to be promulgated, and electronic data began to move towards the historical stage
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.

4. The existing rules of electronic data are
1. The cost of replication is low, and the replication is abrasion free, which can be accurately replicated. The uniqueness of matter in the atomic world is impossible in the bit world
2. Electronic data has no time trace. With the passage of time, the electronic data carrier may change, but the data itself will not change, so it is impossible to compare the time sequence of two electronic data. Compared with the atomic world, the information world lacks a real time dimension
3, electronic time is easy to change, change and lose. There is no "credible" time in bit time, and electronic data can only be a mapping of the information of the atomic world
with the help of blockchain, the security network records the metadata of data preservation on the blockchain, combines encryption algorithm, digital certificate and other technical means, and constructs a more secure and credible trusted mapping from bit world to atomic world, which can prevent hacker attacks< As a result, a complete electronic data link is formed: private certificate + notarization + electronic signature + blockchain = complete electronic data link
development trend of security instry
in the DT era, cloud technology has brought revolutionary changes to electronic evidence, and electronic evidence has been listed in Criminal Procere Law and civil procere law. On January 1, 2013, electronic data as evidence has come into effect in the civil procere law. The demand for electronic data forensics in different regions and instries is growing rapidly, as well as the demand for electronic data preservation and forensics.

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

6.

Using blockchain technology to store and issue electronic evidence is the basis of the application of blockchain technology in the legal field

in the early stage, we took the lead in the instry to set up a blockchain team, invested in the research of cryptography, distributed ledger storage structure, consensus mechanism and other core underlying technologies of blockchain, explored the application scenarios of blockchain technology in the legal science and technology instry, and built a certificate storage alliance chain in parallel with a number of domestic authoritative forensic authentication institutions and notary offices, At present, blockchain technology is mainly used in the field of electronic data distributed storage, including contract storage, e-mail storage, file storage, structured data storage, etc

in the future, we will also make use of blockchain technology to better serve our already mature electronic contract business and the rapidly developing network arbitration business, and make more attempts to blockchain for legal science and technology, so as to promote the application of blockchain technology in the field of judicial or legal services while protecting the security and confidentiality of all parties' systems

7.

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

9.

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

10.

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
