Research And Application Of One Through Card And Mobile Office Under The Hospital Virtual Environment

A variety of business application systems had been deployed and is operating at Luwan branch of Ruijin Hospital in different period which provide powerful supporting means to perform a variety of business.Most of the early application systems had been constructed and deployed based on Client/Server(C/S)architecture pattern,there is big work quantity and inconvenient with aspects of maintenance,upgrading operation system or application software and etc.which require often to configure all the clients one by one in the branch hospital.The early deployed various business application systems are operating in island mode which also produce some difficulty problems such as data share usage and system security management of various application system in the branch hospital.Adopting cloud techniques to integrate each existed application systems into a centralizing operation system and a unifying management platform is a difficulty technical problem which should be solved urgently nowadays in this paper to reduce some system risks of various business application systems with rapid development of computer application techniques.Relative research and description of a practice process had been carried out in this paper for a technical solution scheme and implementation of the difficulty problem.It is a feasible technical solution scheme to integrate each existed application systems by considering adopting present popular virtualization techniques to solve the difficulty technical problem in this paper to integrate various C/S application systems through comparing a variety of relative techniques.A validation via one through card based on ISO/IEC7816 CPU card technology and a management system of authorization for a virtualization mobile office application system in the whole branch hospital had been researched,developed,described and participated in by author of this paper to unify security management for users' login authorities of the each existed application system in a cloud computing environment and to realize data sharing and using effectively.The 3A(Anytime,Anywhere,Anything)office processing had been realized and the effective technical support and safeguard for the integration application of various existed application systems had been provided based on the system in the branch hospital.The primary work described and participated in by author of this paper is summarized as the followings:1.The network hardware environment of the whole branch hospital 's virtualization platform had been participated in by author to research,design and constructed,the stable and reliable supporting and managing platform of cloud operation had been provided for deploying of continuous integrating a variety of business existed application systems.2.The relative techniques about individual user 's file direction reorder anduser 's configuration cruising had been studied and realized.3.The relative standard and its application techniques of ISO/IEC7816 CPU card had been studied and analyzed;the authorization applications had been realized in different environments' thin clients for inserting card login,validation and accessing relative data combined with the a ctual business requirements and the application environment.4.The virtualization technique coordinating individuation application of the thin clients had been studied and realized,inclusion of the relative application technique,implementation scheme,usage method and safety,and realization the safety of accessing the branch hospital 's sensitive data and the transmission aspect for the mobile office processing.5.User name and password of each user inside of the branch hospital isstored in unifying and managed in safety in the backstage security server byadopting the key dispersing technique in safety of ISO/IEC7816 CPU card,and user individuation login account number and validation code(PIN)of theeach user must be written in the user work chest card issued by the branchhospital.The authorized 3A office processing will be allowed to realize whenuser inserts his or her work chest card into any one set of the thin clientsAfter the system described in this paper had been putted in practice operation on line,the amount of system maintenance work is reduced;the safety of the system and the data sharing usage have been effectively safeguarded.Compared with the original existed each business application system operated in island mode,the power consumption of the central room for the backstage servers saves about 80 percent,the physical space of the data storage saves about 40 percent,the usage ratio of the servers' resource enhances about 60 percent,the deploying efficiency for user clients' environment inside of the branch hospital compared with C/S architecture pattern enhances about 50 0 percent.These results validate that each technical work researched participated in and described by author of this paper has effectiveness and the value to be referenced.
