Research Of Security Problem In Long-distance Medical Treatment System

The application research of Web Database technology becomes more widely with the rapid development of Internet. How to utilize web technology to realize long distance diagnose for the purpose of high quality medical service and low medical fees becomes an important task. However, because Internet is an information resource open to different class in society, while network database brings people convenience, it also results in many secure problems. This threatens people's natural work activity from network database greatly. Thus, how to ensure the security of network database becomes a significant problem when we design it.First the paper discusses the security of network and database. Then analyzes popular technology of current network security, mainly investigates the technology of firewall and encrypt. The research involves the study of the data security from the perspectives of server security, user identity authentication and interlocution period security based the analysis of database security. On the basis of above, the paper analyses the current research actuality of network database security, combined with authentication technology,database furbish technology and audit technology,the paper brings forward the general security model of network database.Secondly, from the aspect of database renew, the paper introduces when database system encounters hitch, how to adopt furbish strategy according to malfunction kind to make database comeback to the correct state before malfunction.Finally the paper studies and analyses the current Web database access technology. Common Gateway Interface, the Web server API technology, ASP technology and ASP.NET technology are deeply studied. And analyses their strength and weakness .On the basis of these, the paper puts forward the way of accessing database with the structure of B/S to solve the problem of how to access database in network environment.
