At present, there are many data security mechanisms available in the information security horizon. Many of them mostly emphasize how to make an algorithm that is computationally hard decipher by a cryptanalysis attack. However, in day-to-day life computational power is increasing in the digital world. So recent trend in the data security paradigm is changing from one layer security to two-layer security first layer is called cryptography, which secured against cryptanalysis and second layer is steganography that prevents, as much as possible, against any suspicion of the hidden text.
