Efficient Techniques for Multimedia Information Hiding using Color Visual Cryptography

Rola Al-Khalid, Randa Al-Dallah, Moussa Abdallah


In this paper, a novel approach is presented for multimedia information hiding using visual cryptography. The approach combines both the steganographic and cryptographic effect to improve the quality of security and to increase the payload. Both are important parameters in information hiding. The proposed techniques provide three levels of security without reducing the payload and the image quality. The experiments done on various images and the results obtained showed the robustness of the technique. The proposed techniques are vulnerable to various transformation and geometric attacks and can be considered fragile except for the salt and pepper. The results shown in terms of quality and performance are promising for future work.
