摘要

With the rapid growth of multimedia data in various domains, ensuring the security and integrity of digital content has become a progressively challenging task. Research on multimedia integrity revolves around detection techniques. This paper introduces a new approach to securing the integrity of multimedia data based on the decentralized attributes inherent in blockchain (BC) technology. Our approach enhances the efficiency of hash block calculation for multimedia content (MC) by utilizing bit plane slicing and the first and second decomposition levels of the discrete wavelet transform (DWT). Our evaluation shows a substantial reduction in computational time, all while upholding the integrity of the MC.
