Secret Communication using Cryptography and Steganography

This project proposed RSA and LSB Information Hiding algorithm to improve more security. The idea behind the LSB algorithm is to insert the bits of the hidden message into the least significant bits of the pixels. Achieving the purpose of information hiding with the secret bits of information to replace the random noise, using the lowest plane embedding secret information to avoid noise and attacks, making use of redundancy to enhance the sound embedded in the way nature to be addressed. The results showed that the proposed algorithm has a very good hidden invisibility, good security and robustness for a lot of hidden attacks.However, the limitation of capacity has led us to think about an improved approach which can be achieved through hardware implementation systems with the help of a programmable gate array (FPGA) board. In this process first we generating the Public key and private key for RSA Encryption then we started encryption of RSA using public key then cipher is given as a input to Image then LSB encryption was done then at receiver through LSB decryption he obtains the cipher then through RSA decryption he obtains the original message. It is the process of embedding data within the domain of another data, this data can be text, image, audio, or video contents. The embedded watermark can be visible or invisible (hidden in such a way that it cannot be retrieved without knowing the extraction algorithm) to the human eye, specified secret keys are taken into consideration in order to enhance the security of the hidden data.
