blockchain is a kind of chained data structure that combines data blocks in order according to 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
if you suspect that the blockchain technology of this website is not up to standard, you can register on some larger platforms.
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
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
