Improving re-sampling detection by adding noise
2010
Media Forensics and Security II
Preserved Fulltext
Current image re-sampling detectors can reliably detect re-sampling in JPEG images only up to a Quality Factor (QF) of 95 or higher. ...
At lower QFs, periodic JPEG blocking artifacts interfere with periodic patterns of re-sampling. We add a controlled amount of noise to the image before the re-sampling detection step. ...
INTRODUCTION Digital Image Forensics is a recent field aimed at detecting manipulations in digital images. ...

In our work, we have employed statistical distribution of block variance and AC DCT coefficients of an image to detect global contrast enhancement in an image. ...
In the process of image editing, contrast enhancement is a very common technique to hide visual traces of tampering. ...
These manipulations result in introduction of specific correlations in the statistics of images, which on detection can serve as a sign of digital tampering at detector. ...
