Linear Filter Kernel Estimation Based on Digital Camera Sensor Noise

Chang Liu, Matthias Kirchner
2017 IS&T International Symposium on Electronic Imaging Science and Technology  
We study linear filter kernel estimation from processed digital images under the assumption that the image's source camera is known.  ...  The result is a simple yet accurate filter kernel estimation technique that is relatively independent of image content and that does not rely on hand-crafted parameter settings.  ...  Recent advances in data-driven techniques advocate the idea of general-purpose image forensics, where mostly very high-dimensional feature spaces are chosen to detect, identify, or localize a variety of  ...

Counter-Forensics: Attacking Image Forensics [chapter]

Rainer Böhme, Matthias Kirchner
2012 Digital Image Forensics  
Counter-forensics is first defined in a formal decision-theoretic framework.  ...  Research on counter-forensics is motivated by the need to assess and improve the reliability of forensic methods in situations where intelligent adversaries make efforts to induce a certain outcome of  ...  Acknowledgements Thanks are due to Gang Cao, Thomas Gloe, and Miroslav Goljan for sharing the data of their original research papers.  ...

Remote Check Truncation Systems: Vulnerability Analysis and Countermeasures

Hafiz Malik, Rigel Gjomemo, V. N. Venkatakrishnan, Rashid Ansari, Aun Irtaza
2020 IEEE Access  
The proposed countermeasures rely on tamper detection in digital images and expert-system based decision fusion. The effectiveness of the proposed framework is evaluated using tampered check images.  ...  All major banks in the USA and around the world offer remote check deposit services. Consumers can use their smart phones to deposit checks remotely.  ...  methods and recent advances in image manipulation tools provide an attacker with the opportunity to manipulate a digital check image at the pixel level.  ...

Thus, a different method, flatfielding, is applied to estimate the FPN and the PRNU. FPN is a signal independent additive noise source, while PRNU is a signal dependent multiplicative noise source.  ...  Recently, Chen et al. [2007a] have investigated the PRNU noise signatures proposed in Lukas et al. [2006] to differentiate specific camcorders (e.g., same brand and model).  ...

Conditional Adversarial Camera Model Anonymization [article]

Jerone T. A. Andrews, Yidan Zhang, Lewis D. Griffin
2020 arXiv   pre-print
In contrast to previous works, we cast model anonymization as the process of transforming both high and low spatial frequency information.  ...  Quantitative comparisons demonstrate the efficacy of our framework in a restrictive non-interactive black-box setting.  ...  JTAA is supported by the Royal Academy of Engineering (RAEng) and the Office of the Chief Science Adviser for National Security under the UK Intelligence Community Postdoctoral Fellowship Programme.  ...

A Full-Image Full-Resolution End-to-End-Trainable CNN Framework for Image Forgery Detection [article]

Francesco Marra, Diego Gragnaniello, Luisa Verdoliva, Giovanni Poggi
2019 arXiv   pre-print
In this work, we propose a CNN-based image forgery detection framework which makes decisions based on full-resolution information gathered from the whole image.  ...  Due to limited computational and memory resources, current deep learning models accept only rather small images in input, calling for preliminary image resizing.  ...  In recent years, methods based on deep learning have become dominant.  ...

SpoC: Spoofing Camera Fingerprints [article]

Davide Cozzolino and Justus Thies and Andreas Rössler and Matthias Nießner and Luisa Verdoliva
2021 arXiv   pre-print
This is an important study in order to build better forgery detectors able to face malicious attacks. Our proposal consists of a GAN-based approach that injects camera traces into synthetic images.  ...  Given a GAN-generated image, we insert the traces of a specific camera model into it and deceive state-of-the-art detectors into believing the image was acquired by that model.  ...  Such differences help attribute images to their source camera, but can also be used to better highlight anomalies caused by image manipulations [18, 1] .  ...
