Using Smart Cards in Telemedical Systems
The article is devoted to protecting patient data in the telemedical system which store electronic health records. It shows that in modern systems access to data from the health records may be obtained by any registered employee of the healthcare facility without patient’s knowledge. Therefore, any information can be entered, deleted or changed in such systems. This results in violation of principles of safe access to the information resources of the telemedical system. To solve these problems and ensure confidentiality and integrity of the information this work suggests the use of user smart card, which ensures safe access to the telemedical system. The use of smart cards in the telemedical systems will ensure reliable storage of the confidential patient data. The article describes the capabilities and functions of the smart cards of the patient and physician, and the specifics of their use in the telemedical systems. Security of the information resources is ensured with the help of cryptographic methods. The article discusses the process of the physician’s authorization in the telemedical system, which contains electronic health records. It reviews in detail the procedures of signing documents with electronic digital signature. The article provides block diagrams of the algorithms for creating and verification of the electronic signature. Based on the results of the study, we created an application with a user interface for work with the smart cards
