Selective Encryption for Hierarchical MPEG
نویسندگان
چکیده
Selective encryption of visual data and especially MPEG has attracted a considerable number of researchers in recent years. Scalable visual formats are offering additional functionality, which is of great benefit for streaming and networking applications. The MPEG-2 and MPEG-4 standards provide a scalability profile in which a resolution scalable mode is specified. In this paper we evaluate a selective encryption approach on the basis of our hierarchical MPEG video codec.

Secure Transmission of MPEG Video Sources
In this paper we propose an encryption algorithm for protecting the confidentiality and integrity of MPEG2 bitstreams. The encryption is performed with DES to obtain high performance and small overheads. Several levels of security are presented which make use of selective data encryption. Security and key management issues are discussed.
متن کاملA Selective Video Encryption Scheme for MPEG Compression Standard
With the increase of commercial multimedia applications using digital video, the security of video data becomes more and more important. Although several techniques have been proposed in order to protect these video data, they provide limited security or introduce significant overhead. This paper proposes a video security scheme for MPEG video compression standard, which includes two methods: D...
متن کاملSecurity Analysis of Selectively Encrypted MPEG-2 Streams
Selective encryption exploits the relationship between encryption and compression to reduce encryption requirements, saving in complexity and facilitating new system functionality. Selective encryption of MPEG video streams has been proposed in a number of variations, yet has seen little application to date. Here we focus on high encryption savings, targeting 10% of the bit stream or less encry...
متن کاملMPEG Video Content protection based on Fingerprinting Scheme
The paper presents a system for the secure distribution of a copyrighted video based on fingerprinting scheme. A combined selective watermarking and encryption method that operates in the compressed MPEG domain is introduced. Watermarking resistant to a number of attacks is used for copyright protection. The video quality deteriorates significantly due to encryption, thus restraining unauthoriz...
متن کاملCryptanalysis of Video Encryption Algorithms
Content security is an important issue in multimedia applications. In this paper we perform a cryptanalysis of several encryption algorithms that have been proposed to protect the privacy of MPEG video streams. In particular, we analyze the encryption based on permuting the Huffman codeword list, and two selective encryption algorithms VEA and MVEA. For the convenience of the reader, we provide...
