Problems solved by technology
However, driven by interests, many medical institutions are unwilling to share their data because they are worried that their opponents will develop the next generation of super new drugs
[0005] 2) On the other hand, the security of data sharing is insufficient, that is, privacy security cannot be guaranteed
Although these privacy protection methods guarantee data security to varying degrees, excessive privacy protection will reduce the value of data

The invention discloses a safe data sharing excitation method based on a contract theory. According to the method, the differential privacy is adopted to carry out privacy protection on a data owner so as to ensure privacy safety of a data source end; competitiveness is introduced as a transaction parameter of data sharing, so that the data owner obtains competitiveness, i.e., the technical progress, after sharing data, and the competitiveness worry of the data owner is eliminated; and the contract theory is adopted to solve a problem of information asymmetry between a data demander and the data owner, and an optimal contract is designed to enable a data participant to be benefited. In order to facilitate implementation, the invention further discloses a discretized optimal contract designmethod. According to the invention, the data sharing participant can carry out data sharing by competitiveness excitation on the basis of ensuring privacy safety, and a win-win situation of the dataowner and the data demander is achieved.
Description
technical field [0001] The present invention relates to the technical field of incentive mechanisms for data sharing, and specifically relates to a secure data sharing incentive method based on contract theory between organizations with competitive relationships. Using the present invention in data sharing is conducive to protecting privacy and security, and avoiding third-party privacy possible privacy risks posed by the protection. Background technique [0002] With the advent of the era of big data and artificial intelligence, data-based algorithms and technologies have flourished, giving birth to many data-driven services, such as recommendation services, speech recognition, image recognition, etc., which have profoundly influenced and changed the world. all aspects of economic and social life. These intelligent services are provided by organizations through data collection and analysis, and their service quality depends on a large amount of high-quality data. However,...
