ABSTRACT
The advent of smartphones in recent y ears 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 year s. 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 tak ing subjects’ location and time information into account. The contribution of this paper includes a privacy-preserving access control mechanism for dynamism of wireless access.
