This paper presents a privacy protection system of electronic medical record which deals with the problems of privacy disclosure. Through this system, the patient’s latest medical record can be viewed by patient’s private key with Hash algorithm. The earlier medical record can be viewed only with the private key which is input by the patient himself, which protect the privacy of the patients. Because of the high computational efficiency of the Hash algorithm, the system has a very high efficiency.
