Description
Technical Field
The invention relates to the field of block chain application, in particular to a tracing method of a credible scientific and technological information evidence chain.
Background
In the information-oriented era, the life style of people is greatly changed, so that emerging industries related to the Internet are developed vigorously. However, the infringement means and the right-maintaining means become more diverse and concealed with the development of the internet technology, the traditional evidence form and evidence obtaining means are subjected to more and more impact and challenges, and an emerging evidence storage means, namely electronic data evidence, is gradually used and trusted. However, electronic data also has the characteristics of concealment, diversity and vulnerability, and can be tampered in various links such as acquisition, transmission and analysis, and the electronic data is not easy to leave traces and is difficult to identify. Therefore, the collection and storage of electronic data and the formation of effective evidence are very important, and the corresponding evidence storage industry is produced. As computer technology has advanced, block chain technology has matured. The block chain is a distributed shared account book and data, and has the characteristics of decentralization, no tampering, trace retaining in the whole process, traceability, collective maintenance, openness and transparency and the like. For the electronic evidence, the electronic evidence has the defects of easy tampering and unknown authenticity, the existence of the block chain technology enables the defects of the electronic evidence to be improved and compensated, and the mode of evidence collection through the block chain is a powerful auxiliary and necessary mode for proving the authenticity, objectivity and legality of the electronic evidence. The blockchain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism and an encryption algorithm. The block chain firstly adopts a distributed data storage technology to sequentially link the data blocks according to a time sequence to form a chain data structure, and then an encryption algorithm technology is used to ensure that the data blocks cannot be tampered and forged. Although the electronic evidence is called as "blockchain evidence obtaining", in practice, the electronic evidence is firstly verified through a blockchain technology, and then the evidence is "obtained" through the blockchain technology so as to prove that the electronic evidence is not tampered. The block chain is the comprehensive integration of multiple key technologies such as intelligent contracts, distributed accounts, cryptography, peer-to-peer networks and the like, and has the characteristics of decentralization, openness and transparency, tamper resistance, traceability and the like. The block chain technology does not depend on an additional third-party management mechanism or hardware facilities, does not have central control, and realizes self-verification, transmission and management of information by each node through distributed accounting and storage except for the self-integrated block chain. This feature enables the blockchain to remain more neutral. The block chain technology is open source, except that the private information of each transaction party is encrypted, the data of the block chain is open to all people, and anyone can inquire the data of the block chain and develop related applications through a public interface, so that the information of the whole system is highly transparent. Based on the agreed specification and protocol (various mathematical algorithms such as Hash algorithm adopted by similar bitcoin), the whole blockchain system does not depend on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention. The independence feature makes the blockchain sufficiently neutral on the one hand and also makes it possible to exclude human intervention on the other hand. As long as 51% of all data nodes cannot be mastered, network data cannot be arbitrarily manipulated and modified, so that the block chain per se becomes relatively safe, and subjective and artificial data change is avoided. This reduces the likelihood of human tampering with the data stored in the blockchain technique. The blockchain itself generates blocks in the order of the timestamps, which is continuous and complete, commensurate with the principle of ensuring that the electronic evidence is "continuous and complete". The completeness and continuity of evidence is an important ring for proving the effectiveness of evidence, and particularly for electronic evidence which is easy to modify, electronic technology can completely realize synthesis, time for tampering and the like, so that particular attention is needed. The block chain has the characteristics of difficult tampering and deletion, so that the integrity of the content can be confirmed to a certain degree. First, it is necessary to check whether the electronic data is actually uploaded, and it is possible to confirm the electronic data by searching in the blockchain versus time. Secondly, whether the electronic evidence is the electronic evidence of the complaint or not is examined, the hash value calculation is carried out on the contents such as the webpage screenshot, the source code and the calling information packaging compressed file (the hash value is a numerical value obtained through logical operation according to the data of the contents of the file, and the hash values obtained by different files even if the files have the same file name are different, so that the hash value can be the identity card of one file, and the file verification and verification work can be clearly carried out through the hash value comparison), and the hash value is compared with the electronic data hash value stored in the block chain, if the hash value is consistent, the case-related electronic evidence can be proved to be stored in the block chain, and the case-related electronic evidence is completely stored from the uplink to the previous stage and is not modified. The development of the block chain technology provides a new opportunity for the proof of the electronic evidence, and the proof effectiveness of the electronic evidence is further enhanced. With the rapid development of internet technology and the dependence of people on electronic data such as electronic documents, it is more common that people trade and negotiate through electronic data, but due to the concern of proving effectiveness of electronic evidence, when dealing with large-volume transactions or important contents, people tend to pay more caution and select a more troublesome way of face-to-face docking. The blockchain itself is a chain of evidence that can be used for information tracing and verification.
According to the regulations, the work of information is developed, and the modern scientific and technical means should be fully applied to strengthen the identification of the information. The technology information is converted from information into information, and the authenticity of single information needs to be distinguished, or the information is identified from a large amount of information. In the process, the sources of the intelligence data and the scientific and technical literature are marked, and the contents of indirect citation, such as the contents of plausibility and romance, are checked and quoted with caution.
With the continuous development of internet, distributed and other technologies, the block chain technology is becoming mature. Therefore, the source, the provenance and the use footprint of each piece of information are marked by using the block chain, technical support is provided for the anti-counterfeiting and true-false of the scientific and technological information, the authenticity and the reliability of the scientific and technological information can be ensured, the reliability is improved, the integrity of the evidence chain is ensured, and the application value of the evidence chain is improved.
