Embedded multimedia security systems: algorithms and architectures

Opening with a detailed review of existing techniques for selective encryption, this text then examines algorithms that combine both encryption and compression. The book also presents a selection of specific examples of the design and implementation of secure embedded multimedia systems. Features: reviews the historical developments and latest techniques in multimedia compression and encryption; discusses an approach to reduce the computational cost of multimediaencryption, while preserving the properties of compressed video; introduces apolymorphic wavelet architecture that can make dynamic resource allocation decisions according to the application requirements; proposes a light-weight multimedia encryption strategy based on a modified discrete wavelet transform; describes a reconfigurable hardware implementation of a chaotic filter bank scheme with enhanced security features; presents an encryption scheme for image and video data based on chaotic arithmetic coding. INDICE: Part I: Multimedia Systems.Introduction.Advances in Multimedia Encryption.Securing Multimedia Content using Joint Compression and Encryption.Part II: Examples.Polymorphic Wavelet Transform.The Secure Wavelet Transform.Chaotic Filter Banks.Chaotic Arithmetic Coding.Conclusion.
