Collaborative Location Privacy through Buffering
Journal Title: International journal of Emerging Trends in Science and Technology - Year 2015, Vol 2, Issue 3
Abstract
Location based services available in the smart phones are used to gain information about the surroundings. Users query the location based server by passing their position information thereby losing their privacy. A user collaborative approach to preserve the location privacy was introduced, where the users are hidden from the server when the information is already available among any peer device. This approach cannot be used when the users are not ready to cooperate or the informed users are outside the range of communication of user seeking the information. So in this system a common authentication server is used to store the response from the location based server when any user accesses context information for the first time. This information in authentication server can now be used by other users who require the same information without contacting the server even when the informed users are not nearby. Thus the privacy of the users is found to increase in a considerable manner.
