The E-Health Cloud Platform Now Supports A Keyword Search Related To Timer Use And Lab-Enabled Proxy Recoding

Abstract

The delivery of healthcare may be vastly enhanced by the introduction of novel software, such as an electronic health record system. Users' fundamental concerns about the privacy and security of their personal information may be slowing the systems' widespread adoption. The searchable encryption (SE) method is a promising option for the electronic health record system due to its ability to provide strong security without sacrificing usability. Our research introduces a new cryptographic primitive, which we've termed "Re-dtPECK." It's a time-dependent SE approach that combines conjunctive keyword search with a designated tester and a proxy reencryption function that takes time into consideration. Patients may use this function to provide access to their data to carefully chosen researchers for a short period of time. Any allotted period for a delegatee to view and decode their delegator's encrypted papers may be extended if required. It's possible that the delegate's access and search capabilities will expire after a certain period of time has passed. It's also capable of conjunctive keyword searches and resisting assaults based on guessing. Only the authorized tester is allowed to look for the existence of certain keywords in the proposed method. We provide a system model and a security model for the proposed Re-dtPECK approach to prove that it is a safe and effective replacement for the existing standard. Simulations and comparisons with other methods show that it requires very little bandwidth and storage space for data.
