Problems solved by technology

[0003] However, uploading one's own personal health records to third parties presents many security risks
Personal health records include a lot of personal sensitive information, such as diseases, drugs used, family genetic medical history, etc. If obtained illegally, users will suffer huge losses
On the one hand, cloud servers may illegally view personal health records uploaded by users; on the other hand, servers storing personal health and medical records may become targets of attacks

Embodiment Construction

[0044] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0045] The cloud system environment personal health record storage and access method designed by the present invention, such as figure 1 As shown, applied to the actual application, the cloud system environment includes a storage server, and at least two server authorization centers, and the storage access method includes the following steps:

[0046] Step 01. Use each personal health record uploader as each personal authorization center, combine each server authorization center, and each authorization center will jointly generate a cloud system environment public parameter PK, and obtain the key MK of each authorization center n , and then go to step 02; wherein, n={1,...,N}, N represents the total number of authorized centers.

[0047] The actual execution of the above step 01 specifically includes the following steps...

Abstract

The invention relates to a storage and access method for personal health records in a cloud system environment which employs a multi-authorization center mode. Each authorization center is only responsible for a part of attributes of a user, so that the burden of each single authorization center is reduced and the risks that authority centers leak private information of users is reduced; even attackers break through some authorization centers successfully, the attackers cannot get all the information of a user; the phenomenon that authority centers themselves know much about the attributes of users can also be prevented.

Description

technical field [0001] The invention relates to a method for storing and accessing personal health records in a cloud system environment, and belongs to the technical field of cloud computing security. Background technique [0002] Cloud computing is a new business computing model developed on the basis of distributed computing, grid computing and parallel processing. It aims to use the network to integrate many relatively low-cost computing entities into a powerful Computing power system, and distribute computing power to terminal users with the help of SaaS, PaaS, IaaS and other modes. Due to the above advantages, cloud computing has received extensive attention from academia and industry. PHR (Personal Health Record) personal health record platform is a patient-centered health record platform based on cloud computing. Its service allows users to create and manage their own personal health records through the network, such as allergies, inspection records, Treatment reco...
