Steganography is the art of hiding the fact that communication is taking place, by hiding information in other information. In this paper method is proposed to provide more security for the key information with the combination of image compression and data encryption method. This method requires less memory space and fast transmission rate because of image compression technique is applied. Many different carrier file formats can be used, but digital images are the most popular because of their frequency on the Internet. For hiding secret information in images, there exist a large variety of steganographic techniques some are more complex than others and all of them have respective strong and weak points. Some applications may use absolute invisibility of the secret information, but others require a larger secret message to be hidden. This paper intends to give an overview of image steganography, its uses and technique and its provides better security for encrypted data and no distortion in the image quality.
