In today's world mobile communication has become part and parcel of our daily life. It's hard to imagine today life without the service and application that are provided by the mobile device. These services and applications are basically wireless based and there is always need of secure communication or some kind of channel. Encryption is one way of providing secure communication but most of the existing data encryption techniques are location independent. And here comes the concept of "GeoEncryption" or "Location-Based encryption". It provides an additional layer of security beyond that provided by conventional cryptography. It allows the encryption of data as well as decryption for a specific location(s) or specific area(s) e.g. college campus area or in a particular building. Constraints in time as well as velocity can also be added with respect to the location while encryption. Geoencryption can be used with both fixed and mobile application and supports wide range of data sharing and distribution policy.
