“…They monitor the integrity of the image content but not its numerical representation. Then, the watermark is designed so that the integrity is proven if the content of the image has not been tampered with, despite some mild processing on the image [15].…”

Abstract-Digital watermarking is the process of embedding information into a noise-tolerant digital signal such as image or audio data to easily identify the copyright ownership of the media. Such information is embedded for many different purposes, such as copyright protection, source tracking, piracy deterrence, etc., and therefore it shall be embedded in a way that makes it difficult to be removed. There are an extensive literature about watermarking algorithms and methods as well as possible attack techniques. In this work we collect a part of this vast literature in order to make easy for a non-expert reader about watermarking to have a high-level overview on new trends a technologies related to image and multimedia watermark algorithms and attacks.

“…Clearly, semi-fragile watermarking is only part of a full authentication process since content integrity check additionally requires security assessments. Among the proposed semi-fragile algorithms [1], Eggers and al. [2] were the first to propose a scheme based on the Scalar Costa Scheme (SCS).…”

Semi-fragile watermarking can be used to detect illegal and local manipulation of images, while being robust towards legal manipulations such as lossy compression. This paper describes a gametheoretic approach to design a blind semi-fragile watermarking system based on the Scalar Costa Scheme. A natural choice for the game criterion is a false alarm probability, i.e. the probability to still detect the watermark, even if part of the data has been replaced. Optimal embedding strategy is then derived in presence of a legal processing (e.g. lossy compression, through some model). Finally, the results are applied to design an efficient DCT semifragile watermarking system which allows to detect local forgery signals in spite of JPEG compression.

“…In the context of biometrics, we propose to embed template data as semi-fragile WM information instead of general purpose image descriptors as used in classical semi-fragile WM schemes [2]. This is sensible since on the one hand template data are of course image dependent data and therefore are able to prevent WM copy attacks or similar.…”
