Digital image forensics via intrinsic fingerprints [PDF]
IEEE Transactions on Information Forensics and Security, 2008 Digital imaging has experienced tremendous growth in recent decades, and digital camera images have been used in a growing number of applications. With such increasing popularity and the availability of low-cost image editing software, the integrity of digital image content can no longer be taken for granted. This paper introduces a new methodology for

Digital image forensics for photographic copying
SPIE Proceedings, 2012Image display technology has greatly developed over the past few decades, which make it possible to recapture high-quality images from the display medium, such as a liquid crystal display(LCD) screen or a printed paper. The recaptured images are not regarded as a separate image class in the current research of digital image forensics, while the ...

Evaluation of Digital Image Forensics
2021The development of modern picture handling and altering programming has made the control of advanced pictures simple and impalpable to the unaided eyes. This has expanded the interest to evaluate the dependability of advanced pictures when utilized in wrongdoing examination, as proof in official courtroom and for reconnaissance purposes.

Digital Forensic of JPEG Images
2014 Fifth International Conference on Signal and Image Processing, 2014Since JPEG is the de facto image format adopted in most of the digital cameras and image editing software, tampered image will be often a recompressed JPEG image. As JPEG works on 8 by 8 block cosine transform most of the tampering correlation inherited by tampered image may get destroyed, making forgery detection difficult thus it is common practice ...
