Digital Image Forensics for Identifying Computer Generated and Digital Camera Images
2006 International Conference on Image Processing, 2006We describe a digital image forensics technique to distinguish images captured by a digital camera from computer generated images. Our approach is based on the fact that image acquisition in a digital camera is fundamentally different from the generative algorithms deployed by computer generated imagery.

Digital image forgery — A threaten to digital forensics
2016 International Conference on Circuit, Power and Computing Technologies (ICCPCT), 2016Photography is an art. A digital image is a part of the real world formed after cycles of image generation process. From the initial days of photographic images itself, security and authenticity were major issues. With the era of digital images, the process of altering an image became so popular.

Security of Forensic Techniques for Digital Images
2013Digitale Bilder werden überall im modernen Leben verwendet und ersetzen meist traditionelle Fotografien. Dabei können digitale Bilder oft ohne offensichtlich Beweise mit Hilfe von Bildverarbeitungwerkzeugen verändert werden. Deshalb ist die Überprüfung der Authentizität von Bildern unverzichtbar.

Image steganalysis for digital forensics
2020Στην σημερινή εποχή, η στεγανογραφία είναι ο κύριος τρόπος για την επίτευξη παράνομης μυστικής επικοινωνίας. Ως εκ τούτου, η ανάγκη ανίχνευσης στεγανογραφικού περιεχομένου και ιδίως στεγανογραφημένων εικόνων γίνεται επιτακτική. Ωστόσο, η στεγανάλυση είναι ένα πολύ δύσκολο έργο και η επιτυχία της εξαρτάται από πολλούς παράγοντες, όπως η παρουσία του ...

A survey of passive technology for digital image forensics
Frontiers of Computer Science in China, 2007Over the past years, digital images have been widely used in the Internet and other applications. Whilst image processing techniques are developing at a rapid speed, tampering with digital images without leaving any obvious traces becomes easier and easier. This may give rise to some problems such as image authentication. A new passive tech- nology for

The Impact of Exposure Settings in Digital Image Forensics
2018 25th IEEE International Conference on Image Processing (ICIP), 2018The digital image forensics academic community is facing a growing challenge. The volume of images presented to digital image forensic practitioners increases every day, and with it, more variety of possible outcomes in image analysis. When an academic forensic tool is applied to a realistic case, the effects of imaging factors, including the noise ...

Contrast Enhancement-Based Forensics in Digital Images
IEEE Transactions on Information Forensics and Security, 2014As a retouching manipulation, contrast enhancement is typically used to adjust the global brightness and contrast of digital images. Malicious users may also perform contrast enhancement locally for creating a realistic composite image. As such it is significant to detect contrast enhancement blindly for verifying the originality and authenticity of ...
