Abstract—Video encryption has been heavily researched in the recent years. This survey summarizes the latest research results on video encryption with a special focus on applicability and on the most widely-deployed video format H.264 including its scalable extension SVC. The survey intends to give researchers and practitioners an analytic and critical overview of the state-of-the-art of video encryption narrowed down to its joint application with the H.264 standard suite and associated protocols (packag-ing / streaming) and processes (transcoding / watermarking).

Abstract. In this work an efficient format-compliant encryption approach for regular languages is proposed, block-based cycle-walking. The approach can transparently trade-off security for efficiency and can be adjusted to the desired level of security. The relationship between the encryption of regular languages and the encryption of JPEG2000 bitstreams is established. Block-based cycle-walking for the regular language of JPEG2000 bitstreams is compared to the extensive previous work from the multimedia security community and to the previous work from the cryptographic community, which is analyzed and evaluated.

Abstract. GVid is a Grid service that enables the secure and transparent integration and development of graphical user interface applications in the Grid. It separates the potentially computationally complex task of data creation and visualization, e.g., scientific simulations, from the comparably computationally inexpensive task of transmission and display of the visual data. A Grid application produces visual data and GVid takes care of the encoding, the secure and efficient transmission and the display of the visual data. As the transmission parameters and grid node properties are highly variable, special compression schemes have to be chosen to cope with these requirements. Beneficial for such requirements is the application of scalable compression formats, such as H.264/SVC (Scalable Video Coding) and MC-EZBC (Motion-Compensated Embedded Zerotree Block Coding). As simulation data may be sensitive, e.g., in the case of medical simulations, the secure transmission and storage of the visual data has to be guaranteed. Format-specific encryption schemes offer improved functionality due to the preservation of scalability in the encrypted domain. In this work the compression performance of state-of-the-art scalable video compression systems is evaluated and format-specific encryption schemes are proposed and discussed. 1.

Abstract Taking advantage of the inter-layer prediction technique used in H.264/SVC (Scalable Video Coding), in this paper we propose an efficient block-based encryption scheme (BBES) for encrypting H.264/SVC enhance-ment layers. BBES operates in three modes, namely, Intra-MB mode, Group-MB mode and 4Group-MB mode. All the three modes are effective in se-curing enhancement layers, preserve the “adaptation-transparent ” property of H.264/SVC, and are format-compliant to the H.264/SVC bitstream for-mat specifications. Moreover, Intra-MB and Group-MB modes also possess the property we termed as “transcoding-transparency”. Experimental results indicate that BBES has low computational complexity and small compression overhead. Thus, BBES is suitable for transparent encryption of H.264/SVC bitstreams in which enhancement layers are encrypted but base layers are left

Universal Multimedia Access (UMA) calls for solutions where content is created once and subsequently adapted to given requirements. With regard to UMA and scalability, which is required often due to a wide variety of end clients, the best suited codecs are wavelet based (like the MC-EZBC) due to their inherent high number of scaling options. However, most transport technologies for deliv-ering videos to end clients are targeted toward the H.264/AVC standard or, if scalability is required, the H.264/SVC. In this paper we will introduce a map-ping of the MC-EZBC bitstream to existing H.264/SVC based streaming and scaling protocols. This enables the use of highly scalable wavelet based codecs on the one hand and the utilization of already existing network technologies without accruing high implementation costs on the other hand. Furthermore, we will evaluate different scaling options in order to choose the best option for given requirements. Additionally, we will evaluate different encryption options based on transport and bitstream encryption for use cases where digital rights management is required.

Abstract. GVid is a Grid service that enables the secure and transparent integration and develop-ment of graphical user interface applications in the Grid. It separates the potentially computation-ally complex task of data creation and visualization, e.g., scientific simulations, from the comparably computationally inexpensive task of transmission and display of the visual data. A Grid application produces visual data and GVid takes care of the encoding, the secure and efficient transmission and the display of the visual data. As the transmission parameters and grid node properties are highly variable, special compression schemes have to be chosen to cope with these requirements. Benefi-cial for such requirements is the application of scalable compression formats, such as H.264/SVC (Scalable Video Coding) and MC-EZBC (Motion-Compensated Embedded Zerotree Block Coding). As simulation data may be sensitive, e.g., in the case of medical simulations, the secure transmis-sion and storage of the visual data has to be guaranteed. Format-specific encryption schemes offer improved functionality due to the preservation of scalability in the encrypted domain. In this work the compression performance of state-of-the-art scalable video compression systems is evaluated and format-specific encryption schemes are proposed and discussed. 1.
