Privacy Protection of Medical Service Data Based on Blockchain and Artificial Intelligence in the Era of Smart Medical Care

Abstract

Smart medical care will realize the self-management, selection, and optimization of related things with more thorough induction, more comprehensive interconnection, and more intelligent insight, so that people can get an increasingly personalized medical and health service experience. 5G-enabled Internet of Things and AI (artificial intelligence) will continue to drive innovative applications in the medical industry. Access control and sharing of medical data is of great significance to the development of smart medical care, but the security problems in medical data sharing cannot be ignored. In this paper, a privacy protection scheme of medical service data based on blockchain and AI is proposed. The user chain is constructed as a public chain. In the user chain, the data privacy of users is protected, and users can safely transmit data to doctors and realize the management of session keys. CNN (convolutional neural network) privacy protection protocol based on homomorphic encryption can protect users’ privacy input, server model parameters, and calculated intermediate values. Experimental analysis and comparison with other schemes show that the scheme in this model is safer and more practical.

A strategy to balance location privacy and positioning accuracy

“…The performance of BLPPA-AIP is tested using the publicly available dataset from the Geolife project of Microsoft Research Asia. In order to simulate different scenarios, we set up three scenarios: sparse scenario, normal scenario, and dense scenario, and the number of users in different scenarios is set to 100, 200, and 300, respectively [34], with the number of cooperative users taking the value of 10, and the radius of the user's coverage is 250 meters. In each experiment, given the location of a mobile user, we use a different approach to formulate a selection…”

Service quality evaluation of county-level public hospitals in Chongqing under smart healthcare

“…Smart healthcare is the use of advanced information technology to promote the modernization of healthcare services [1,2], to provide patients with convenient [3], e cient [4], and safe healthcare services [5], to alleviate the "di cult to see" and "expensive" problem [6]. In recent years, with the deep integration of the Internet and the healthcare industry, local governments and healthcare institutions at all levels actively promote the construction of smart healthcare, and the introduction of relevant policies and guidelines, smart healthcare has become the industry's development trend [7].…”
