Location based data encryption methods and applications

In todays world, mobile communication has tremendous demand in our daily life. The use of the mobile user´s location called Geo-encryption, produces more secure systems that can be used in different mobile applications. Location Based Data Encryption Methods (LBDEM) are used to enhance the security of such applications called as Location based Services (LBS). It collects position, time, latitude and longitude coordinates of mobile nodes and uses for the encryption and decryption process. Geo-encryption plays an important role to raise the security of LBS. Different Geo-protocols have been developed in the same area to add security with better throughput. The (AES-GEDTD) is such an approach which gives higher security with a great throughput. In this paper, we discuss AES-GEDTD as a LBDEM approach and its role in some applications like Digital Cinema Distribution, Patient Telemonitoring System (PTS) and Military Application.
