Blockchain evidence

Innovation is the driving force of development, and the protection of intellectual property rights is to protect and encourage innovation, so as to promote the progress and development of economy and society

take the example of micro right, a blockchain intellectual property protection platform of e-baoquan, which combines intellectual property protection with digital technology, and uses the characteristics of stable and tamper resistant blockchain storage to store work data on the blockchain in the form of hash encryption for blockchain confirmation, so as to help users register relevant information of works in the blockchain

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

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

6. Because Xu Mingxing thinks that the blockchain technology itself can not be used as evidence, it only ensures the authenticity of the data information with legal effect on the chain. In case of infringement disputes, it is the data information stored on the chain, not the blockchain itself, as evidence.

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
