Abstract. Digital watermarking studies have always been driven by the improvement of robustness. Most of articles of this field deal with this criterion, presenting more and more impressive experimental assessments. Some key events in this quest are the use of spread spectrum, the invention of resynchronization schemes, the discovery of side information channel, and the formulation of the opponent actions as a game. On the contrary, security received little attention in the watermarking community. This paper presents a comprehensive overview of this recent topic. We list the typical applications which requires a secure watermarking technique. For each context, a threat analysis is purposed. This presentation allows us to illustrate all the certainties the community has on the subject, browsing all key papers. The end of the paper is devoted to what remains not clear, intuitions and future studies.

“…Both assessment model and performance index are very important tools to distinguish different algorithms, and as we know, security is a very special performance index different from robustness, so the assessment model for security is a research hotspot [11][12][13]. The analysis methods of watermarking security can be divided to three classes [14]: analysis method based on information theory proposed by Shanoon, analysis method based on Fisher information matrix and analysis method based on computation complexity.…”

Abstract. The idea of side information is introduced into secure watermarking, and a secure watermarking model with side information theory and the idea of cryptography is proposed. In the proposed model, the side information from the cover work, the attack and the detector are considered and fully used in both the preprocessing stage and the embedding stage. With the guidance of the proposed model, we also give three security mechanisms resisting typical secure attacks, such as collusion attack, homology detection and copy attack, which belong to unauthorized removal, unauthorized detection and unauthorized embedding. The proposed security mechanisms show that the side information and encryption technology can be used to get good watermarking algorithms with higher security.

“…High-granular requirements may be secrecy, integrity or authenticity of the watermark, dependency of the watermark on the cover-data (to prevent copy attacks), as well as robustness and collusion tolerance to name only the most important ones. Barely any application (if any at all) requires a single watermarking scheme to provide all these high-granular properties 9 , beside the fact that it is a difficult, and unnecessary, task to design such watermarking scheme.…”

“…Comesaña et al [8,9] closely follow the inadequate notion of security (information leakage) introduced in [6,7] as mentioned above. Their main achievement, compared to [7] is the definition of a new measure to quantify the leaked information and its application to spread spectrum watermarking.…”

Abstract. Multimedia security schemes often combine cryptographic schemes with information hiding techniques such as steganography or watermarking. Example applications are dispute resolving, proof of ownership, (asymmetric/anonymous) fingerprinting and zero-knowledge watermark detection. The need for formal security definitions of watermarking schemes is manifold, whereby the core need is to provide suitable abstractions to construct, analyse and prove the security of applications on top of watermarking schemes. Although there exist formal models and definitions for information-theoretic and computational security of cryptographic and steganographic schemes, they cannot simply be adapted to watermarking schemes due to the fundamental differences among these approaches. Moreover, the existing formal definitions for watermark security still suffer from conceptual deficiencies.In this paper we make the first essential steps towards an appropriate formal definition of watermark robustness, the core security property of watermarking schemes: We point out and discuss the shortcomings of the existing proposals and present a formal framework and corresponding definitions that cover those subtle aspects not considered in the existing literature. Our definitions provide suitable abstractions that are compatible to cryptographic definitions allowing security proofs of composed schemes. MotivationMultimedia applications deploy various cryptographic and watermarking techniques to maintain security. Typical application scenarios are dispute resolving, proof of authorship and asymmetric and anonymous fingerprinting.In this context, the security analysis and security proofs for the resulting composed schemes require a suitable formal framework and reasonable security definitions. Modern cryptography already uses established formal models and definitions for information-theoretic and computational security. Inspired by cryptographic methodology similar approaches have been proposed for
