Hash Function: Application to Video Sequences
نویسندگان
چکیده
This paper presents an interesting application of the Tillich-Zémor function TZ . In particular, we emphasize the concatenation property of this one-way hash function, i.e. TZ(S j T ) = TZ(S)TZ(T ) where S and T are two binary strings. This property is combined with a multisignature scheme in a journalism context. The aim is to authenticate reports or interviews.

Authentication of Sequences with the SL2 Hash Function: Application to Video Sequences
This paper presents an interesting application of the Tillich-Zémor function TZ . In particular, we emphasize the concatenation property of this one-way hash function, i.e. TZ(S | T ) = TZ(S) TZ(T ) where S and T are two binary strings. This property is combined with a multisignature scheme in a journalism context. The aim is to authenticate reports or interviews.
متن کاملAn Improved Hash Function Based on the Tillich-Zémor Hash Function
Using the idea behind the Tillich-Zémor hash function, we propose a new hash function. Our hash function is parallelizable and its collision resistance is implied by a hardness assumption on a mathematical problem. Also, it is secure against the known attacks. It is the most secure variant of the Tillich-Zémor hash function until now.
متن کاملAdaptive Spectral Separation Two Layer Coding with Error Concealment for Cell Loss Resilience
This paper addresses the issue of cell loss and its consequent effect on video quality in a packet video system, and examines possible compensative measures. In the system's enconder, adaptive spectral separation is used to develop a two-layer coding scheme comprising a high priority layer to carry essential video data and a low priority layer with data to enhance the video image. A two-step er...
متن کاملSecuring Video Integrity Using Decentralized Trusted Timestamping on the Bitcoin Blockchain
The ability to verify the integrity of video files is important for consumer and business applications alike. Especially if video files are to be used as evidence in court, the ability to prove that a file existed in a certain state at a specific time and was not altered since is crucial. This paper proposes the use of blockchain technology to secure and verify the integrity of video files. To ...
متن کاملFast Frame-Accurate Mining for Repeating Video Clips
In the broad range of multimedia content analysis tasks the detection of recurring video sequences plays an important role. We introduce an algorithm for recognizing recurring video sequences frame-accurately in a highly effective and efficient way. It does not require temporal segmentation by shot detection. A 24 hour live-stream can be processed in about 4 hours including the computational ex...
