Blockchain certificate storage process
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
Blockchain, with the characteristics of decentralization, distributed accounting, whole process trace and traceability, has laid the foundation for intellectual property blockchain certification
when the work is completed, users can upload the electronic data of the work to the blockchain for multi node and decentralized encryption storage through the micro right, which is the intellectual property protection platform of the blockchain under ebac, and use fixed and tamper proof blockchain technology to save the certificate, and store the electronic data in the form of hash value to the blockchain to ensure that the data can not be tampered, Through the Beidou satellite timing, the evidence time can be solidified, and the right certificate issued by the right bureau can be applied online
in case of disputes, users can directly submit the evidence of blockchain to the court, which can effectively improve the efficiency of rights protection
In order to meet the growing demand for litigation services of the people in the process of regional collaborative development between Sichuan and Chongqing, our blockchain certificate keeping technology will play a series of roles such as certificate keeping, authentication and evidence collection in cross domain case filing, petition joint control, online litigation, joint conference and other cooperation between Sichuan and Chongqing, making long-distance and contactless cooperation more standardized, convenient and efficient. To provide assistance for Sichuan Chongqing high court to achieve inclusive, equal, convenient, efficient, intelligent and accurate litigation services
this paper briefly introces the application of blockchain evidence storage -- "real hammer" trusted electronic evidence platform
Real hammer "trusted electronic evidence platform, through cooperation with forensic authentication institutions, notary offices, arbitration institutions, Internet courts, etc., realizes the storage, retrieval and issuance of evidence on the chain, and reces the cost of electronic data evidence preservation, It is convenient for electronic data collection and evidence identification, and improves the litigation efficiency in the field of judicial evidence preservation
at present, the evidence traceability mode of "real hammer" trusted electronic evidence platform has been recognized by many courts in Beijing, Xiamen, Guangzhou and Shenzhen, and some banks and state-owned enterprises have begun to use "real hammer" trusted electronic evidence platform
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 />
Using blockchain technology to store and issue electronic evidence is the basis of the application of blockchain technology in the legal field
in the whole life cycle of electronic data generation, collection, transmission and storage, blockchain technology can protect electronic data, prevent tampering, and leave traces of data operation
using blockchain technology to preserve electronic evidence, the electronic data that needs to be deposited 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 deposit. 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 litigation efficiency
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

In short, blockchain is a distributed bank accounting system, a trust network without central institutions, and a distributed database. Because of its distributed storage, decentralization and other characteristics, it can effectively prevent tampering and repudiation, and has incomparable system stability compared with the traditional mode
based on the above characteristics, blockchain technology has been combined with the financial instry, and has been applied on a large scale, and has made remarkable achievements. In August 2016, we, together with onchain, jointly launched an open blockchain alliance "falian" based on Microsoft trusted cloud technology and open platform, and Microsoft comprehensive technology and open platform
based on the technical support of "French chain", we have reached a cooperation with Alibaba mailbox and launched the world's first e-mail deposit proct based on blockchain technology. With the growth of the Internet environment, the demand for e-Cert will also grow, and our "legal chain" will play a greater role
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
