Abstract

The invention provides a health record access control system and method in electronic medical cloud. The system comprises a medical management center unit used for generating a system public key and asystem private key, and generating a corresponding user attribute private key according to the system public key, the system private key and a user attribute set; an electronic medical cloud storageunit used for receiving and storing health record ciphertexts with privacy protection; and at least one health record user access unit used for encrypting health records according to the system publickey to obtain the health record ciphertexts with privacy protection; and / or generating the user attribute set and decrypting the health record ciphertexts with privacy protection according to the system public key and the user attribute private key. By adoption of the health record access control system and method in electronic medical cloud provided by the invention, the confidentiality of the health records is not only guaranteed, and the security and the computational efficiency of the health record access are also improved.

Description

technical field [0001] The present invention relates to the technical field of information security, in particular to a health file access control system and method in an electronic medical cloud. Background technique [0002] With the rapid development of technologies such as wireless communication and cloud computing, the application prospect of electronic medical cloud in the medical industry is becoming more and more broad. However, most medical information systems still have serious "islands" and "chimneys" at multiple levels. . The main reasons for this phenomenon are as follows: First, there is a lack of information between various fields such as medical care and public health, between hospitals and communities; second, there is a lack of information between different institutions in the same field, and information between different departments within the same institution In a small number of institutions, the same department, the same post, or even the same person u...
