Abstract
The advent of smartphones in recent years has changed the wireless landscape. Smartphones have become a platform for online user interface to cloud databases. Cloud databases may provide a large set of user-private and sensitive data (i.e., objects), while smartphone users (i.e., subjects) provide location-sensitive information. Secure and private services in wireless accessing to cloud databases have been discussed actively for the past recent years. However, the previous techniques are unsatisfactory for dynamism of moving subjects' wireless accesses. In this paper, we propose a novel technique to dynamically generate virtual private databases (VPD) for each access by taking subjects' location and time information into account. The contribution of this paper includes a privacy-preserving access control mechanism for dynamism of wireless access.

The dynamism of wireless accesses is taken into consideration for setting up permitted database subsets
Summary
Cloud computing models [1] give benefits to workflow management in various application domains where location varies and workflow covers vast wide areas. Subjects may want to access objects in cloud databases, and their supervisors are changed based on location and time. It is likely that over the course of workflow, location and time information of objects and subjects change Such changes are not necessarily stored in a central cloud but sometimes stored in the smartphone memory or a local virtual machine. This dynamism of privilege grant and revocation based on subject’s location and time has not considered successfully The goal of this project is to provide to each subject with a virtual private database (or vpd in short) which is dynamically generated depending on the location and time and so serve for moving subjects and objects.
