Abstract
In recent years, the GPS location information can be effortlessly obtained through smart devices such as smart phone, tablet PC and camera. The obtained GPS information can be utilized for two main purposes, namely geo-tagging and tracking. GPS enabled various innovative applications such as photo album arrangement, tracking of taxi/bus, estimation of calories burned during an outdoor cycling session, etc. However, the storage of GPS information has not been addressed sufficiently and hence it can be easily tampered. This study surveys the current storage method for GPS location information. The drawbacks are identified and the data embedding approach is proposed as a more flexibly and practical way in storing the GPS location information. In particular, data embedding methods are proposed to embed the GPS information in text, audio, image and video contents that can be handled by a smart device. Discussion on possible applications are also presented.
