Abstract

Provided is a method of managing medical information in an operating system for a medical information database, the method including encrypting, by a first user, first medical information having patient treatment information by using a group key, and second medical information having patient private information by using a private key, generating, by the first user, an index corresponding to the encrypted first medical information, storing the encrypted first and second medical information and the index to the medical information database, searching, by a second user, the medical information database for the encrypted first medical information by using the index; and decrypting the searched encrypted first medical information by using the group key.

Claims

1. A method of managing medical information in an operating system for a medical information database, the method comprising:

encrypting, by a first user device, first medical information having patient treatment information by using a group key, and second medical information having patient private information by using a private key corresponding to the first user;

generating, by the first user device, an index corresponding to the encrypted first medical information by selecting one or more representative keywords;

storing the encrypted first and second medical information and the index to the medical information database;

searching, by a second user device, the medical information database for the encrypted first medical information by using the index; and

decrypting the searched encrypted first medical information by using the group key.

2. The method of claim 1, further comprising,

performing authentication by inputting an ID and a password through an input window, by the first and second users device respectively.

3. The method of claim 1, wherein the patient treatment information comprises diagnosis, prescription, a hospitalization date, a hospital discharge date, or a disease code, and the patient private information comprises a name, an age, a phone number, a resident registration number, an address, or a patient ID.

4. The method of claim 1, wherein the second user device is identical to the first user device, the method further comprising decrypting, by the first user device, the encrypted second medical information by using the private key.

5. The method of claim 1, further comprising encrypting the index using the private key.

6. The method of claim 1, wherein the medical information further comprises other information besides the first and second medical information, the method further comprising:

encrypting the other information using the group key;

storing the encrypted other information in the medical information database; and

decrypting the encrypted other information using the group key.

7. The method of claim 6, wherein the other information comprises hospital administration information.

8. The method of claim 7, wherein the hospital administration information comprises all certificate management information, treatment fee management and health insurance practice, and hospital administration statistics.
