AN EFFECTIVE VIDEO STEGANOGRAPHY USING RC4 ALGORITHM
Abstract
Privacy is a critical issue when the data owners outsource data storage or processing to a third party computing service, such as the data security. In this paper, we identify a data security computing application scenario that requires simultaneously performing secure watermark detection and privacy preserving multimedia data storage. We then propose a principle component analysis based color coded frame extraction matrix (PCA)-based framework using secure multiparty computation (mpc) protocols to address such a requirement. In our frame-work, the multimedia data and secret watermark pattern are presented to the data security for secure watermark detection in steganography domain to protect the privacy. During matrix transformation, the privacy of the matrix and the watermark pattern is protected by the mpc protocols under the semi- honest security model. We derive the expected watermark detection performance in the matrix domain, given the target image, watermark pattern, and the size of the matrix matrix (but without the matrix matrix itself). Our theoretical analysis and experimental results showthat secure watermark detection in the matrix domain is feasible than ACS scheme.
