The invention discloses an electronic health case storage access method comprising the following steps: a trusted secret key authorization mechanism initializes and generates a public key and a main secret key; the trusted secret key authorization mechanism uses the main secret key to verify IDs of medical work personnel so as to generate a medical personnel access control voucher with an effective period; the trusted secret key authorization mechanism verifies patient IDs so as to generate a patient access control voucher; the patient access control voucher, the medical personnel access control voucher and an access strategy are packaged; the package is verified and stored if the package passes the verification; a release request is received and verified, if release requesting person inputted content is the corresponding patient access control voucher or the medical personnel access control voucher in the package, then the request passes the verification and releasing is carried out. The advantages are that the method can realize effective access control, and can maximumly protect the safety of the electronic health cases stored in an incompletely trusted third party server, thus saving decryption cost of mobile equipment.
Description
technical field [0001] The invention belongs to the field of cryptography in information security, and specifically designs a method for storing and accessing electronic health cases. Background technique [0002] The development of electronic health records (EHRs) to make electronic health systems work has received a great deal of attention, both academically and industrially. Because compared with traditional paper health records (PBHR), EHR can be stored and shared more flexibly. Because it is in digital form, different types of health data, such as prescription documents, medical images such as X-rays, B-ultrasound, audio clips, or video files, can be included in a person's EHR account, and can be easily accessed. To find a person's EHR, the patient and his doctor can simply retrieve them from a stored server, rather than wade through a room full of documents. These features give EHR advantages that PBHR cannot match. The Veterans Administration's health care system i...
