IMAGE STEGANOGRAPHY USING IMPROVED LSB ALGORITHM.

The goal of Steganography is to hide communication. So, a fundamental requirement of this Steganography system is that the hidden message should not be visible to human beings. The other goal of this method is to avoid suspicion to the presence of hidden message. This technique has recently became important in a number of application areas. The project has various objectives such as: ? To produce security tool based on Steganography techniques ? To enhance techniques of hiding data using encryption. ? To extract hidden data using decryption methods. Steganography is sometimes used when encryption is not allowed. An encrypted file may still hide information using Steganography, so even if encrypted file is deciphered, the hidden message is not seen. The objective of ?Steganography? is to increase the efficiency of a system to reduce the manual labour.
