Robust and efficient authentication of video stream broadcasting
ACM Transactions on Information and System Security, 2011We present a novel video stream authentication scheme which combines signature amortization by means of hash chains and an advanced watermarking technique. We propose a new hash chain construction, the Duplex Hash Chain, which allows us to achieve bit-by-bit authentication that is robust to low bit error rates.

Video-to-video face authentication system robust to pose variations
Expert Systems with Applications, 2013High-quality still-to-still (image-to-image) face authentication has shown success under controlled conditions in many safety applications. However, video-to-video face authentication is still challenging due to appearance variations caused by pose changes.

Video streaming authentication over lossy channels
2007We consider the problem of source and content authentication in video streaming applications in multicast satellite networks. In this paper we pro-pose a novel method that combines digital signa-ture with watermarking techniques. The proposed approach does not introduce bandwidth overhead while the computational overhead introduced by digital signature

Robust Hashing Based Video Content Authentication
Journal of Information and Computational Science, 2013Nowadays, robust hashing has been widely adopted in video content authentication. The hash is resistant to common video processing operations, but vulnerable to video malicious attacks. Existing hashing methods to authenticate video, however, usually fail to make a good trade-off between robustness and security.

AUTHENTIC VIDEO MATERIALS: ADVANTAGES AND LIMITATIONS
The article discusses the benefits and challenges of using authentic video materials in language learning. Authentic materials refer to videos created for native speakers, rather than language learners, and thus reflect real-world language use with natural speech patterns, idioms, and cultural contexts.openaire +1 more source
