碩士 === 中原大學 === 醫學工程研究所 === 90 === Due to the prosperous development in information technology (IT), the idea to facilitate the internet/intranet in hospitals for the exchange of medical information and reducing of administrative is well established. However, the concern about data is accompanied with IT infrastructure construction. These concerns include whether hackers may steal or alter the content of medical information; Any illegal access may happen intentionally. Thus, network security is becoming a crucial factor in the growth and development medical information system of the Internet. This research mainly focuses on enhancing network security of referral system between National Taiwan University hospital and Logkog’s hospital. There are four aspects in designing such system: 1. Confidential information--coding the electronic medical information for transmission of safety. 2. Data integrity--preventing unauthorized alternation of the electronic medical information transmission. 3. Identification--identifying password administration on both sides network system. 4.Access control--precaution have no enough the right body can access data in the database. To reach the above security requirement, this study integrates the SSL (Secure Sockets Layer) and the Virtual Private Network (VPN) mechanism for data transmission safety. It also exploits a Filter and a source code modification method and to establish an authorization mechanism. This study is also thoroughly analyzed the safe capability and evaluated the communication load with the safety mechanism implemented. In addition, this research also analyze the affect of Ddos hacker attack to the established referral system.
