Linking with medical institutes and medical related centers. the individual patient's information should be studied systematically and synthetically. Since the medical information contains the fatal information for the individual patient, it should not to be released of operated by an unauthorized person. The individual medical information, distributed at various medical institutes, can be intergrated through a medical health IC card. This paper describes a mechanism to access and secure the information on a medical health IC card. Facilitating appropriate access rights for the information recorded on a medical health IC card. it should prohibit an authorized person from browsing patient's private information. From the previous studies on a medical health IC card, the items on a medical health IC card are categorized into eight different groups conforming to the international standard. Proposed system further refined the eight Global Classes into an Interest Class and Detail Class, and sets up a new access rights for each class. The memory file system of a medical health IC card also follows the existing international standard. Besides, this paper describes issues about how the operator plays a role in handling the access process for medical health information. The study also follows the international standard by standardizing the items stored in a medical health IC card. In the future, the security level and access limitations have to be more refined and localized to be fit in Korean environment.
