Design And Implementation Of Shanxi Tobacco Mobile Terminal Security Assistant

With the continuing improvement of the management for Shanxi Tobacco information system,Shanxi Tobacco brings modern information mobile terminal into the work for sale management in order to realize the information data communication,and this technique greatly improved the work efficiency,however,the security problem of informations was brought up as well.How to solve the security problems which hanges on the improving work efficiency with morden technology,increase the efficiency and reduce the risk,has become an important task for the sale information management.As the information technology,especially the technology of mobile platform rapidly improved,developing security software for mobile terminals has become one of the directions to pushing forward for the information management of Shanxi Tobacco.Shanxi Tobacco mobile terminal is a customized hardware based on Android,considering the information security,Shanxi Tobacco prohibit to install third-party software in the mobile terminal,the tobacco market supervisors who use the terminal hardware urgently need a software to realize mobile terminal function such as information security protection,offline attendance.Android built-in components and interfaces provide a guarantee to achieve functional requirements,broadcast and receiver mechanisms in Android invoke alarm and lock screen according to SMS commands when SIM card changes,I compared the hash value of the application with third-party virus database to achieve the virus killing function,I used the blocking mechanism to achieve the Android system broadcast harassment blocking.I used Google's open-source scanning library ZXing to scan the Quick Response Code,and used SQLite to query offline retail customers information.In this paper a mobile terminal security assistant based on the Android OS design and implementation were studied,for current status and the needs of the mobile terminal work,focusing on the description and analysis of the needs of the security assistant,the overall structure,and the specific design and implementation process.The software used the Java language,had been successfully put into use after a period of testing,and it's in good operating condition.It satisfies the market supervisors'requirements both for mobile terminal information security protection and auxiliary work.
