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 speciic security which have to be reconsidered. We will identify a basic characteristic of these security issues, adaptability, to answer the dynamics.
