Abstract
With the rapid popularization of the Internet and the Information Office of medical institutions, a large amount of electronic medical information has been generated. Medical information involves the privacy of the patient. At present, many lawless use various means to obtain the patient’s privacy information and take advantage of it for benefits. At present, there are many research methods of medical data access control, but the structure of medical data is complex, and the amount of data is huge. The contradiction between privacy protection and data utilization is still difficult to balance. A method of medical information access control based on weighted information entropy is proposed for the privacy protection and data utilization of electronic medical information. This method uses information entropy to measure the amount of information that a medical information visitor possesses, and sets different weights for different kinds of privacy information to assist in computing information contents. Method sets the tolerance of information and compares the amount of information the visitor has with the tolerance. The access strategy decides whether to feed back the requested medical information according to comparison result. After security analysis and comparison, this method can effectively protect the patient’s privacy information and meet the needs of the legitimate visitors.
