Empirical Evaluation of PRNU Fingerprint Variation for Mismatched Imaging Pipelines [article]

Sharad Joshi, Pawel Korus, Nitin Khanna, Nasir Memon
2020 arXiv   pre-print
We assess the variability of PRNU-based camera fingerprints with mismatched imaging pipelines (e.g., different camera ISP or digital darkroom software).  ...  We show that camera fingerprints exhibit non-negligible variations in this setup, which may lead to unexpected degradation of detection statistics in real-world use-cases.  ...  In this work, we empirically assess the sensitivity of PRNU fingerprints to mismatched imaging pipelines.  ...

Multimedia Forensics Before the Deep Learning Era [chapter]

Davide Cozzolino, Luisa Verdoliva
2022 Advances in Computer Vision and Pattern Recognition  
We will focus on methods that rely on the extraction of a camera fingerprint and need some prior information on pristine data, for example, through a collection of images taken from the camera of interest  ...  Using such conventional signal processing methods, it is possible to modify images and videos obtaining very realistic results.  ...  Government is authorized to reproduce and distribute reprints for Governmental purposes notwithstanding any copyright notation thereon.  ...

Media Forensics and DeepFakes: an overview [article]

Luisa Verdoliva
2020 arXiv   pre-print
This review paper aims to present an analysis of the methods for visual media integrity verification, that is, the detection of manipulated images and videos.  ...  Therefore, there is an urgent need for automated tools capable of detecting false multimedia content and avoiding the spread of dangerous false information.  ...  All images acquired by a given camera bear traces of its PRNU pattern, which can be therefore regarded as a sort of camera fingerprint.  ...

Image Forgery Detection and Localization via a Reliability Fusion Map

Hongwei Yao, Ming Xu, Tong Qiao, Yiming Wu, Ning Zheng
2020 Sensors  
On the basis of fingerprints acquired by images from different camera models, the goal of this paper is to design an effective detector capable of completing image forgery detection and localization.  ...  The extensive results from our empirical experiments demonstrate the effectiveness of our proposed RFM-based detector, and its better performance than other competing approaches.  ...  Thus, it is proposed to enhance the effectiveness of the CNN equipped with pre-processing stage for capturing image intrinsic fingerprints.  ...

Digital image forensics: a booklet for beginners

Judith A. Redi, Wiem Taktak, Jean-Luc Dugelay
2010 Multimedia tools and applications  
Digital visual media represent nowadays one of the principal means for communication.  ...  Two main problems are addressed: the identification of the imaging device that captured the image, and the detection of traces of forgeries.  ...  Detection of PRNU for single images is then formulated as a Neyman-Pearson hypothesis testing problem.  ...
