A Bayesian Approach to Affine Transformation Resistant Image and Video Watermarking [chapter]

Gabriella Csurka, Frédéric Deguillaume, Joseph J. K. Ó Ruanaidh, Thierry Pun
2000 Lecture Notes in Computer Science  
This paper proposes a new approach for assessing the presence of a digital watermark in images and videos.  ...  To do that, the Bayesian approach allows the deduction of the relative logprobability of the presence of a watermark in an image given only the key.  ...  Acknowledgments We are grateful to Shelby Pereira and Svyatoslav Voloshynovskyy for a number of interesting discussions on the subject, and to Dr A.  ...

Confronting the Synchronization Problem of Semantic Region Under Geometric Attacks

Paraskevi Tzouveli, Klimis Ntalianis, Stefanos Kollias
2006 2006 IEEE International Conference on Multimedia and Expo  
In this paper, an affine invariant watermarking scheme, robust to geometric attacks, is proposed and applied to face regions.  ...  Initially, face regions are unsupervisedly extracted from an initial image and a normalization procedure, invariant to geometric attacks is applied on each of these regions using a set of specific moment  ...  This approach can be used as a public watermarking scheme, providing robustness to general affine geometric attacks.  ...

A Residual Chaotic System for Image Security and Digital Video Watermarking

Guoxiang Tong, Zhehua Liang, Fengjun Xiao, Naixue Xiong
2021 IEEE Access  
The invisibility is good, the watermark capacity has been significantly improved, and the video bit-rate growth rate is in a good range.  ...  The watermark can resist attacks such as noise and the bit error rate under re-encoding and Gaussian low-pass filtering attacks.  ...  In addition to traditional standards, literature [29] proposed a method for image encryption, using affine transformation and bit manipulation.  ...

Association of Moving Objects Across Visual Sensor Networks

Muhammad J. Mirza, Nadeem Anjum
2012 Journal of Multimedia  
Although two complementary watermarks are embedded simultaneously to provide higher detection response, each watermark could resist a specific class of attacks.  ...  SIFT feature is a type of local invariant feature, which is propose by Lowe et al. and proved to be invariant to image scale and rotation, also robust to a substantial range of affine distortion, change  ...  At last, a case study from the developed prototype system shows the feasibility and flexibility of this method under distributed CAD environment.  ...

Anti-collusion fingerprinting for multimedia

W. Trappe, Min Wu, Z.J. Wang, K.J. Ray Liu
2003 IEEE Transactions on Signal Processing  
These fingerprints are typically embedded into the content using watermarking techniques that are designed to be robust to a variety of attacks.  ...  We demonstrate the performance of our ACC for fingerprinting multimedia and identifying colluders through experiments using Gaussian signals and real images.  ...  Another approach to constructing BIBDs is to use -dimensional projective and affine geometry over , where is of prime power. Projective and affine geometries yield and BIBDs [34] , [36] .  ...

Comprehensive Feature-based Robust Video Fingerprinting Using Tensor Model [article]

Xiushan Nie, Yilong Yin, Jiande Sun
2016 arXiv   pre-print
The robust video fingerprinting framework is resistant not only to single-mode modifications, but also to the combination of them.  ...  Most existing video fingerprinting methods use a single feature or concatenating different features to generate video fingerprints, and show a good performance under single-mode modifications such as noise  ...  Watermarking is a traditional technology used to detect copies of images or videos. It embeds imperceptible watermarks into the media to prove its authenticity.  ...

Bayesian structural content abstraction for image authentication

Wei Feng, Zhi-Qiang Liu
Proceedings 7th International Conference on Signal Processing, 2004. Proceedings. ICSP '04. 2004.  
In this paper, we propose a structural content abstraction scheme within the Bayesian framework, based on which an implicit and reliable image authentication scheme can be established.  ...  Although the numerous existing algorithms can detect and locate malicious alterations to the protected image, unfortunately, most are still too fragile to resist various content-preserving manipulations  ...  , affine transformation, enhancing and blurring etc., while detecting "content altering" modifications (i.e., COs), such as object adding, removal and replacement etc.  ...
