Multimedia Encryption

In a wireless environment, multimedia transmission is often affected by the error rate; delaying; terminal’s power or bandwidth; and so forth, which brings difficulties to multimedia content protection. In the past decade, wireless multimedia protection technologies have been attracting more and more researchers. Among them, wireless multimedia encryption and watermarking are two typical topics. Wireless multimedia encryption protects multimedia content’s confidentiality in wireless networks, which emphasizes on improving the encryption efficiency and channel friendliness. Some means have been proposed, such as the format-independent encryption algorithms that are time efficient compared with traditional ciphers; the partial encryption algorithms that reduce the encrypted data volumes by leaving some information unchanged; the hardware-implemented algorithms that are more efficient than software based ones; the scalable encryption algorithms that are compliant with bandwidth changes; and the robust encryption algorithms that are compliant with error channels. Compared with wireless multimedia encryption, wireless multimedia watermarking is widely used in ownership protection, traitor tracing, content authentication, and so forth. To keep low cost, a mobile agent is used to partitioning some of the watermarking tasks. To counter transmission errors, some channel encoding methods are proposed to encode the watermark. To keep robust, some means are proposed to embed a watermark into media data of low bit rate. Based on both watermarking and encryption algorithms, some applications arise, such as secure multimedia sharing or secure multimedia distribution. In this chapter, the existing wireless multimedia encryption and watermarking algorithms are summarized according to the functionality and multimedia type; their performances are analyzed and compared; the related applications are presented; and some open issues are proposed.

Confidentiality Protection

Since the past decade, multimedia protection technologies have been attracting more and more researchers. Among them, multimedia encryption and watermarking are two typical ones. Multimedia encryptionen codes media data into an unintelligible form, which emphasizes on confidentiality protection. Multimedia watermarking embeds information into media data, which can be detected or extracted and used to authenticate the copyright. Traditionally, in multimedia distribution, media data are encrypted and then transmitted, while the copyright information is not considered. As an important application, to trace illegal distributors, the customer information (e.g., customer ID) is embedded into media data, which can trace illegal distributors. In this chapter, the multimedia distribution scheme based on watermarking technology is investigated, which realizes both confidentiality protection and copyright protection. Firstly, some related works, including multimedia encryption and digital watermarking, are introduced. Then, the existing watermarking-based distribution schemes are reviewed and analyzed. Furthermore, the novel scheme is proposed and evaluated. Finally, some open issues are presented.

Multimedia encryption innovation is one of the primary ways of securely and privately guaranteeing the security of media transmission. There are many advantages when utilizing the attributes of chaos, for example, arbitrariness, consistency, ergodicity, and initial condition affectability, for any covert multimedia transmission. Additionally, many more benefits can be introduced with the exceptional space compliance, unique information, and processing capability of real mitochondrial deoxyribonucleic acid (mtDNA). In this article, color image encryption employs a confusion process based on a hybrid chaotic map, first to split each channel of color images into n-clusters; then to create global shuffling over the whole image; and finally, to apply intrapixel shuffling in each cluster, which results in very disordered pixels in the encrypted image. Then, it utilizes the rationale of human mitochondrial genome mtDNA to diffuse the previously confused pixel values. Hypothetical examination and trial results demonstrate that the anticipated scheme exhibits outstanding encryption, as well as successfully opposes chosen/known plain text, statistical, and differential attacks.
