Continuous Location Based Services for User Defined Privacy Grid System

Abstract

Location-based services (LBS) requires users to constantly position reports is likely to be unreliable for location-based services, which may jeopardize the privacy of the server. Unfortunately, the techniques of preserving the privacy of LBS has many restrictions, such as requiring a completely reliable third party, and offers few guarantees of privacy and incurring high above the connection. In this paper, we propose Privacy distribution network knowledge by the user called bio-network system (DGS), the first totalitarian regime manages four basic conditions for a cat to maintain privacy and LBS continuous. (1) The system requires only one-third of medium trust, is responsible for implementing a simple matching operations correctly. Is this a trusted third party has almost no information on where the user is present. (2) is guaranteed safe for a cat and privacy site continuously in our models specific discount. (3) The cost of the call the user does not depend on the privacy required for the user level, it just depends on the amount of corresponding points in the vicinity of the user area. (4) despite the fact that we focus only on the scale investigations and closest in this paper neighbor, our system can be easily expanded to support queries and other algorithms without spatial changes managed by trusted third parties almost started and the server database, provided that the required surface for the spatial query can extract the spatial regions. The results showed that our DGS is the most effective method of prior art LBS Privacy happening.
