Security is major concern for the transmission of multimedia data. To protect multimedia content from intruder is much more crucial task. Many cryptographic techniques are already available for providing security to multimedia content. This paper proposes Two-phase security of images with the help of encryption & steganography technique. This provides security to images from intruder with the help of two important cryptographic techniques i.e. Encryption and Steganography. Here, both these techniques are used at two different phases. In phase-I, encryption is used for converting the input image into cipher image with the help of encryption key. Chirikov mapping is used for encryption of image. In phase-II, steganography is used for hiding the encryption key of phase-I into cipher image. The goal of the system for the implementation is not only protecting image but the key also. It also reduces the cost for transmission of key and adds some level of security to key and image also.
