System and method for controlling anonymous hospitalizing and security access of medical information based on property

Abstract

The invention discloses a system and a method for controlling anonymous hospitalizing and security access of medical information based on property. The method is that the property encrypting and symmetric encrypting technologies are adopted to protect the security and privacy of the medical record information of a patient; the broadcasting encrypting technology and group signature technology based on groups are utilized to achieve anonymous registration and hospitalization of the patient, so as to protect the privacy of the patient. With the adoption of the method, the difficulty in key management caused by the increase of users can be avoided; meanwhile, the calculation burden caused by frequent key updating and ciphertext updating due to canceling of authorization can be reduced; in addition, a detailed scheme is provided according to the actual hospitalization process, and moreover, the authorization process in emergency conditions is provided according to the emergency conditions in actual life.

Description

technical field [0001] The invention belongs to the technical field of cloud data information security, and in particular relates to an attribute-based anonymous medical treatment and medical information security access control system and method. Background technique [0002] With the progress and development of society, especially the promotion of the concept of smart city, more and more data will be uploaded to the cloud server for sharing, which will bring greater convenience to people's life. However, when a large amount of data is uploaded to the server, the security and privacy of the data become a security issue that needs to be solved urgently. Especially when medical information with a high degree of privacy is shared on a cloud server, the confidentiality and security of the information need to be guaranteed. Therefore, when uploading information, the information needs to be encrypted. In addition, with the improvement of people's awareness of privacy protection,...

AI Technical Summary

Problems solved by technology

It is not possible to achieve such a control: if the user has not received medical treatment in this medical unit, he does not want this medical unit to access the data

Other schemes use each user to generate their own attribute encryption scheme, so that each user will get the key distributed by all other users, and the management of the key at this time has become a more difficult problem

In addition, these solutions only consider the access control of medical information, and do not propose a substantive solution to protect the user's medical privacy in combination with the actual process of the user's medical treatment.
