A mobile database is a database that can be connected to by a mobile computing device over a mobile network. Mobile processed information in database systems is distributed, heterogeneous, and replicated. They are endangered by various threats based on user's mobility and restricted mobile resources of portable devices and wireless links. Since mobile circumstances can be very dynamic, standard protection mechanisms do not work very well in such environments. So the authors proposed model enhances the security in mobile database system. In this paper, they develop a security model for transaction management framework for peer-to-peer environments.
