Certificate of Jingdong blockchain
at present, a number of third-party right preservation platforms based on blockchain technology have emerged in China. The originator can use the electronic data provided by the platform as electronic evidence in case of right disputes.
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.
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
compared with the traditional right registration, the use of blockchain technology for right storage has the characteristics of convenient operation, fast and low cost. Traditional right registration not only needs complicated application materials, but also has a long processing cycle and relatively high cost. For example, the registration fee for photographic and artistic works is 300 yuan, and the fee for written and oral works (more than 10000 words) is also 300 yuan. The issuing time of traditional right registration is generally 25-30 working days, while the cost of blockchain right certificate is much lower, and the certificate can be issued immediately. Therefore, blockchain right preservation provides a low-cost and efficient way for right registration.
Through the record number on the forensics certificate, you can also directly query the blockchain on the official websites of easy security, notary office and Arbitration Commission, including the preservation subject, preservation timestamp, Guangzhou Internet court evidence number, blockchain hash value and other relevant information, so as to ensure the openness, transparency and traceability of blockchain storage data
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.
