Security Issues In Mobile Database Access

: Mobile computing and communication is a rapidly developing area. But mobility is associated with problems for security and privacy beyond those in open networks. A well known threat is tracking user movements. New risks are caused by the mobility of users, the portability of computers, and wireless links which include dynamics, resource dependencies and additional information to ensure the communication. This paper surveys the new challenges and the research on security issues in mobile data management, access and transfer. We investigate the issues concerning database specific security which have to be reconsidered. We will identify a basic characteristic of these security issues, adaptability, to answer the dynamics. INTRODUCTION The development of mobile devices make new applications conceivable through ubiquitous computing. For example, mobile work "on-the-spot" like disaster recovery and maintenance tasks as well as business trips are possible. Mobile computing and communicatio..
