Research on symmetric fuzzy search of medical data outsourcing system under intelligent network

Abstract

Abstract Intelligent networks have developed rapidly in various fields of the world today. As a popular network technology, they have broad application prospects in the fields of telemedicine and health monitoring. The application of this technology has important practical significance for solving many aspects of medical treatment. Aiming at the encryption scheme of fuzzy keyword search and the verifiable problem of the data returned by medical cloud in the security of medical cloud data, this paper analyzes the encryption of medical data outsourcing system on medical cloud and the security search method. A verifiable fuzzy keyword symmetric searchable encryption scheme for medical cloud data outsourcing system is proposed, which not only uses symmetric encryption algorithm, but also supports the search of fuzzy keyword and supports the verification of search results. So that the confidentiality of medical data is guaranteed, medical data administrators in the medical outsourcing data uploaded to the medical cloud server before the medical outsourcing data encryption, when patients or other medical users need to obtain a file, through keyword query to the medical cloud to make a request, so as to ensure that their privacy. It also ensures the integrity and security of the returned results.
