“…Our work deals with content authentication software based implementation. The state-of-the-art authentication schemes for H.264/AVC video fall into two broad categories: (1) content-dependent also called digital signature-based authentication where the watermark can be fragile or semi-fragile (Farfoura, Horng, Guo, & Al-Haj, 2015) according to the integrity criteria, and (2) content-independent authentication in which the watermark is only fragile (Le, Nguyen, & Tran, 2014). The authentication based on fragile watermarking, also called hard authentication (Bovik, 2010;Feng, Siu, & Zhang, 2013;Zhu, Swanson, & Tewfik, 2004) is able to find the regions where the content has been modified.…”

Discrete Cosine transform (DCT) to generate the authentication data that are treated as a fragile watermark. This watermark is embedded in the motion vectors (MVs) The advances in multimedia technologies and digital processing tools have brought with them new challenges for the source and content authentication. To ensure the integrity of the H.264/AVC video stream, we introduce an approach based on a content fragile video watermarking method using an independent authentication of each Group of Pictures (GOPs) within the video. This technique uses robust visual features extracted from the video pertaining to the set of selected macroblocs (MBs) which hold the best partition mode in a tree-structured motion compensation process. An additional security degree is offered by the proposed method through using a more secured keyed function HMAC-SHA-256 and randomly choosing candidates from already selected MBs. In here, the watermark detection and verification processes are blind, whereas the tampered frames detection is not since it needs the original frames within the tampered GOPs. The proposed scheme achieves an accurate authentication technique with a high fragility and fidelity whilst maintaining the original bitrate and the perceptual quality. Furthermore, its ability to detect the tampered frames in case of spatial, temporal and colour manipulations, is confirmed.

“…Here, the basic approach, inspired by B. Le, H. Nguyen and D. Tran [12], is to shrink a video so that only frames with a recurrent vortex nerve Betti number of interest are retained in a video. Video shrinking (i.e., video frame elimination) is achieved by deleting those frames represented by gaps between occurrences of frames that yield consecutive sequences of a particular vortex nerve Betti number.…”

This article introduces an application of Ghrist barcodes in the study of persistent Betti numbers derived from vortex nerve complexes found in triangulations of video frames. A Ghrist barcode is a topology of data pictograph useful in representing the persistence of the features of changing shapes. The basic approach is to introduce a free Abelian group representation of intersecting filled polygons on the barycenters of the triangles of Alexandroff nerves. An Alexandroff nerve is a maximal collection of triangles with a common vertex in the triangulation of a finite, bounded planar region. In our case, the planar region is a video frame. A Betti number is a count of the number of generators in a finite Abelian group. The focus here is on the persistent Betti numbers across sequences of triangulated video frames. Each Betti number is mapped to an entry in a Ghrist barcode. Two main results are given, namely, vortex nerves are Edelsbrunner-Harer nerve complexes and the Betti number of a vortex nerve equals k + 2 for a vortex nerve containing k edges attached between a pair of vortex cycles in the nerve.
