Encryption is a process which uses a finite set of instruction called an algorithm to convert original message, known as plaintext, into cipher text, its encrypted form. To secure the exchange of important multimedia data over the internet, steganography techniques are extensively used in recent years. By using such techniques the sensitive data is hidden in covert object making its existence imperceptible to the intruder during transmission. In our project we mainly use system Reversible-Data-Hiding method for embedding and extraction of secret image. It depends on the histogram-shifting. We basically have two phase they are embedding phase and extracting phase.
