| With the changes in the health care system now, the hospital accompanied by drug rebateinformation generated new meaning, now including hospital information refers to the amount ofinformation collected specific hospital medicine, this information can be learned by differentdoctors dosage, with these drugs the amount of information related to drug sales organizations andpersonnel in accordance with the dosage information to the relevant doctor paid kickbacks,resulting in obvious contradiction between doctors and patients now. Hospital information security,in particular the management of hospital information has now become important to ensure that thereform of the health care system hub links, has become an important part to curb drug prices.As information technology continues to mature and evolving applications, the hospital hascarried out most of the domestic construction of hospital information, the establishment of ahospital information system (Hospital Information System, referred to as the HIS system) made alot of achievements, hospital information construction situation better. With data from thedrawbacks is the hospital’s HIS system in which, once HIS security system is compromised canlead to serious consequences. How to improve the safety and reliability of hospital informationsystems, effective management of the HIS system sensitive data, ensure information security HISsystem, it is very urgent.Although the response to this situation, the existing HIS systems also take a variety ofhardware and software by way of precaution, but there is still a lot of loopholes. In this thesis, thedevelopment of domestic research status of information security, through field research the city’sthree hospitals and four secondary hospitals, and with the hospital management, medical personnel,Information Division staff and other personnel exchange forum, Hospital information on theactual situation of the status quo analysis of the development of the main hospital informationaccess mode is suitable for hospital, decided to apply advanced data encryption technology, designdata related hospital audit function, through the transparency of hospital information systems transformation, while the hospital room for the corresponding safety management and other means,to disclose information about the behavior of hospital data control and prevention, and to design adata encryption based hospital information systems.Based on data encryption hospital information system information data security is extremelyimportant, so based on the information and data security features data encryption hospitalinformation systems must be able to verify the information reflects the internal management ofdata information systems, internal identification system information and user levels in the use ofdata generated in the course of the transfer storage stability and no lack of sex. Can be based onthe nature of work and the operational characteristics of the various departments of the hospitals,design different segments or subnets based data encryption medical information systems, healthdepartments in the internal network application conditions permit, medical information datanetwork layer address the data link layer address binding, enabling to prevent address spoofingpurposes. Based on data encryption hospital information system is to reinforce the software fordatabase security, security through this hospital information software system that can effectivelyprevent unauthorized users from bypassing firewalls hospital HIS system attacks outside of thesystem, but also to prevent the Internal users steal drug sales data. By testing for hospitalinformation system based on the proven data encryption security of the system, to ensure thereliability and safety of hospital data. |
