The techniques of camouflage information have acquired a vital role with the requirement of intensifying trade of multimedia content. Steganography is the technique that utilizes disguise in a way that prohibits unauthorized access from suspicion of the existence of confidential information exchanged during communication channels between the connected parties. In this paper, an integrated image steganographic system is designed to conceal images, messages or together where the mainly deliberate the improvement of embedding capacity through embedding text with image simultaneously. For that purpose, used matrix partition to partition the secret image then embedded each partition separately after scrambling each pixel by replacing msb instead of lsb to provide the second level of security furthermore to steganography. The simulation results clarify the better performance of the proposed algorithms.

The Internet is the essential wellspring of data in the present life where it offers the trade of data to the clients.The exchange of such data prompts an incredible security danger. Cryptography and steganography are two issues in security systems.Cryptography jumbles the message to be incomprehensible While Steganography shroud the message To be invisible. Therefore, Encryption any private data before concealing in the cover object will provide twofold security. This paper presents a technique for disguise message with four levels of security where the message first encrypt using modifying vernam cipher, in which the initial key originate automatically from random pixel of camouflage cover and alter continuously along message length then embedded cipher message in grayscale cover image, after that encrypt this cover using modifying vernam cipher also then embedded it in RGB color cover image. The simulation consequence illustrates that the scheme provides better protection.

Nowadays, due to the rapid development of the internet, it is prominent to guard mystery data from cyberpunks through communicating. The steganography technique utilizes for trading mystery data in an approach to stay away from doubt. This paper accomplishes a manner for encryption each channel of RGB color image separately without the necessity to exchange an encryption key utilizing the principle of modifying vernam scheme then camouflage it into a grayscale cover image .On the other hand, encrypts a grayscale image without the necessity to exchange an encryption key utilizing the principle of modifying vernam scheme then camouflage it into a cover image of RGB color type. The simulation results revealed an offering of extremely security for the image transmission.
