Blockchain record storage includes
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
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
Blockchain deposit, in short, is to store electronic data on the blockchain for deposit and preservation
micro right is a brand of EBAO. The data of works confirmation, network forensics and preservation through micro right will be stored on the blockchain in the form of hash. Relying on the characteristics of decentralized blockchain and distributed storage, the blockchain can store evidence, effectively ensuring the originality and non tamperability of electronic evidence
at present, it has won the instrial Internet pilot demonstration project of the Ministry of instry and information technology of the people's Republic of China in 2018 (the only selected project of blockchain) and the first batch of domestic blockchain information service filing enterprises of the state network information office in 2019< br />
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.
The relevant certificates can be issued online for the data of blockchain storage and network forensics through easysaving. Through the record number on the certificate, the blockchain query can be concted directly through the official website of easysaving and relevant arbitration commission, including the preservation subject, preservation time stamp, Guangzhou Internet court evidence number, blockchain hash value and other relevant information
at present, financial management is mainly carried out by information system, including LIS system, PACS system and OA system in addition to his system [5]. At present, except for the hospitals with advanced technology in some developed areas, most hospitals have not yet achieved a high degree of integration between the systems. Therefore, the differences in basic operation algorithms, data collection and feedback methods lead to the poor timeliness of information disclosure of each mole of the financial system, which can not meet the requirements of government departments for financial transparency. With the support of blockchain technology, the hospital's various mole systems can operate in an integrated way, and the system data of different sectors can be extracted and shared in time, which lays a solid foundation for the integration of hospital's financial system accounting, budget implementation, capital revenue and expenditure, financial analysis, etc
2. Deepen the content of financial management
with the continuous deepening of medical reform, the business volume of medical institutions has increased, and the more refined the financial management is required. However, the current hospital financial management is far from enough segmentation. Under the diversified changes of medical insurance and expenditure, the lag of information statistics seriously hinders the accurate and automatic operation of the financial system. Strictly speaking, hospital financial management only includes budget management, cost management and other contents, and subsequent other expenses are easy to be connected in the calculation process, which can not meet the needs of financial function integration process. Therefore, we should sort out the existing financial work, take the financial budget, revenue and expenditure as the source of management, and bring the medical project research funds, operating funds, expenditure approval into the scope of financial management. The introction of blockchain technology into the hospital financial management system can not only realize the above financial management steps, but also investigate and track the use of funds in real time, so as to realize the traceability of the source and the clarity of the direction of funds in the process of investigation. In this way, the horizontal development of financial content can fully improve the efficiency of hospital financial management
3. Improve the efficiency and accuracy of hospital financial management
hospital financial management plays an important role in the daily operation of the hospital, and also determines the accuracy of hospital financial information. The hospital should focus on improving the financial management to prevent and control the economic crisis caused by the financial management failure. In terms of the current enterprise financial management, the application of blockchain technology and AI intelligence is the overall development trend. Therefore, the combination of blockchain technology is an important grasp to upgrade the hospital financial management system. Affected by the characteristics of the hospital instry and the limitations of technical means, in the past, the financial management was mainly based on post inspection accounting, and the financial changes were involved early and the control was relatively lacking. In the face of increasingly detailed cross department financial data, the traditional financial management audit mode needs a lot of manpower in the aspects of evidence query, audit judgment and financial budget. The distributed bookkeeping technology and weak centralization of blockchain technology make it automatic and efficient to record financial transaction data after the verification of blockchain network nodes There are complete and remarkable characteristics in time and space. The hospital financial system built by blockchain technology can collect all kinds of effective financial data in real time and conct dynamic analysis according to the smart contract, which greatly improves the efficiency and precision of hospital financial management_ To ensure the safety of financial management in all departments of the hospital
4. Strengthen financial budget management
traditional hospital financial management is usually based on the past frequency of equipment use and the range of drug use. Some hospital financial managers think that it is only necessary to allocate resources according to the requirements of higher authorities, which leads to the intelligent financial system can not be well implemented in the hospital financial budget management system. The smart contract part in the blockchain technology can effectively enhance the control of hospital funds. The so-called smart contract is a program that automatically processes assets based on blockchain technology according to preset conditions. Blockchain technology is characterized by significant independence from the participation of third parties, so it is only necessary to input the funds allocated to the budget into the blockchain from the source, and the traceability and whereabouts of the budget funds can be presented clearly and transparently [7]. Smart contract mechanism can ensure the reasonable use of budget funds, and obviously eliminate the illegal use. In addition, blockchain technology can monitor the budget execution in real time and give early warning to the budget data changes with different usage. With the help of the self settlement (clearing) function in the smart contract, the transaction settlement (clearing) can be automated and fast, which can significantly rece the error rate of financial personnel and improve the budget implementation effect

Blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies
in a narrow sense, blockchain is a kind of chained data structure composed of data blocks connected in sequence according to the time sequence, and it can not be tampered with and forged by cryptography
it is an important feature of electronic contract system, which can not be tampered with and forged, and effectively improve the security of electronic contract
in 2016, we, together with Microsoft (China) and onchain, jointly launched the establishment of "French chain", which deeply integrates electronic contract and blockchain technology. Digital fingerprint information such as signing time, signing subject and file hash value of electronic contract will be broadcast to the respective nodes of all members of "French chain". Once all the information is stored, no party can tamper with it, so as to realize the anti tampering of electronic evidence and ensure its objective authenticity
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.
