Now-a-days, data security is making a way into market. New techniques of data security have gained interest of many researchers. Encryption-decryption technique is one such way of data security. These techniques not only provide confidentiality, integrity of data but also help in authentication of user. Authentication is possible because encryption-decryption of the data is only possible with the legitimate key possessed by legitimate user only. In this paper, the authors study different technique used in encryption method so to increase security of data especially location based encryption and decryption process.
