Emerging new trends of location based systems security

Location Base System (LBS) is considered one of the most beneficial technologies in our modern life, commonly imbedded in varies devices. It helps people find their required services in the least amount of time based on their positions. The users submit a query with their locations and their required services to an un-trusted LBS server. This raises the flag of user privacy where the user has to have the right to conduct services with keeping their location or identity concealed. This research will cover introduction to LBS Services and Architecture components. Security threats to LBS, related work to providing security while conducting LBS services which will include checking integrity of provided location information (LI), privacy of end user vs identifying end user for security purposes. Privacy of end user based on key anonymity and the four different LBS security approaches based on key-anonymity which are: Encryption-based K-anonymity, MobiCache, FGcloak and Pseudo-Location Updating System. Comparison and analysis of the four stated LBS security approaches and finally enhancements and recommendations.
