Embodiment Construction

[0041] Considering the real application scenario, we assume that medical institutions can be interconnected through the medical system network, and the owners of medical records can also log in to the medical system network to view their own records through identity verification. According to information such as patient information, medical treatment time, medical institution, and medical treatment type, the system will automatically generate an index idx for each medical record of the patient. This index can uniquely identify an electronic medical record and can be used for records within the medical system search. In order to reduce storage expenses, the internal network of the medical system only needs to store the relevant retrieval information of each medical record, and the content of the medical record is stored in the cloud.

Abstract

The invention provides a secret sharing cloud storage method. The method includes the preprocessing state, the distribution stage, the reconstruction stage and the recovery and verification stage. At the preprocessing stage, preprocessing is conducted on electronic medical records through the HC-A, and the preprocessing result is directly used for the distribution stage; at the distribution stage, n shares are generated through the HC-A and distributed to the CP1, the K and the CPn; at the reconstruction stage, the CPre obtains t or more shares from the CP1, the K and the CPn, and the preprocessing result of the electronic medical records are recovered and sent to the HC-B; at the recovery and verification stage, the electronic medical records are recovered through the HC-B, and the correctness of the electronic medical records is verified. According to the method, while it is ensured that the calculation cost of users is reduced, it can be ensured that neither cloud service providers storing the electronic medical records nor cloud service providers recovering the electronic medical records can obtain the records.

Description

technical field [0001] The invention relates to the technical field of cloud computing security, in particular to an outsourced reconfigurable secret shared cloud storage method suitable for electronic medical records. Background technique [0002] In recent years, with the continuous development of cloud computing technology and the increasing number of cloud service providers, cloud computing services have entered people's lives more and more deeply. Today, the exchange of medical records between different medical institutions is very inconvenient, and patients often need to carry physical cases when they visit different medical institutions. In addition, the poor communication of medical record information has also brought many obstacles to medical research. With the convenience provided by cloud computing, we can digitize medical records and store them in the cloud. The introduction of electronic medical records (EHR) in the medical system will allow patients' medical ...
