Digital images are everywhere—from our cell phones to the pages of our online news sites.
How we choose to use digital image processing raises a surprising host of legal and ethical …

One of the principal problems in image forensics is determining if a particular image is
authentic or not. This can be a crucial task when images are used as basic evidence to …

It is often desirable to evaluate an image based on its quality. For many computer vision
applications, a perceptually meaningful measure is the most relevant for evaluation; …

Due to the popularity of JPEG as an image compression standard, the ability to detect
tampering in JPEG images has become increasingly important. Tampering of compressed …

A new approach to detecting forgery in digital photographs is suggested. The method does
not necessitate adding data to the image (such as a Digital Watermark) nor require other …

Recently well-designed adaptive steganographic systems, including±1 embedding in the
DCT domain with optimized costs to achieve the minimal-distortion [8], have posed serious …

The threat posed by hackers, spies, terrorists, and criminals, etc. using steganography for
stealthy communications and other illegal purposes is a serious concern of cyber security …

Discriminating computer generated graphics from photographic images is a challenging
problem of digital forensics. An important approach to this issue is to explore usual image …

We are undoubtedly living in an age where we are exposed to a remarkable array of visual
imagery. Nowadays, accepting digital images of official documents is common practice …

We propose statistical image models for wavelet-based transforms, investigate their use,
and compare their relative merits within the context of digital image forensics. We consider …
