A Semi‐Fragile Video Watermarking Algorithm Based on H.264/AVC
Wireless Communications and Mobile Computing, Volume 2020, Issue 1, 2020., 2020 With the increasing application of advanced video coding (H.264/AVC) in the multimedia field, a great significance to research in video watermarking based on this video compression standard has been established. We propose a semifragile video watermarking algorithm, which can simultaneously implement frame attack and video tamper detection, herein.

Semi-Fragile Watermarking Authentication with Local and Global Watermarks [PDF]
, 2006 In this paper, a novel semi-fragile watermarking authentication scheme is proposed, which is based on two watermarks: the local watermark and the global watermark. The two watermarks complement each other. The local watermark is generated from the quantized ACs in 8×8 DCT block.

Reversible watermarking scheme with image-independent embedding capacity [PDF]
, 2005 Permanent distortion is one of the main drawbacks of all the irreversible watermarking schemes. Attempts to recover the original signal after the signal passing the authentication process are being made starting just a few years ago. Some common problems,
