Steganalysis using image quality metrics

IEEE Transactions on Image Processing, 2003
We present techniques for steganalysis of images that have been potentially subjected to steganographic algorithms, both within the passive warden and active warden frameworks. Our hypothesis is that steganographic schemes leave statistical evidence that can be exploited for detection with the aid of image quality features and multivariate regression ...

Steganalysis of Halftone Images

Proceedings. (ICASSP '05). IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005., 2006
We present a novel steganalysis technique for halftone images without knowledge of the original cover image. We first convert halftone images into grayscale-like images by low-pass filtering. The low-pass-filtered image is then decomposed using quadrature mirror filters, and a set of subband coefficients are generated at different scales and ...

Steganalysis of overlapping images

SPIE Proceedings, 2015
We examine whether steganographic images can be detected more reliably when there exist other images, taken with the same camera under the same conditions, of the same scene. We argue that such a circumstance is realistic and likely in practice. In `laboratory conditions' mimicking circumstances favourable to the analyst, and with a custom set of ...

Image steganography and steganalysis

WIREs Computational Statistics, 2011
AbstractImage steganography is used to embed covert messages in the form of files, text, or other images in digital images. The intent is to transmit hidden information. Steganalysis is the process used to detect hidden messages in images. Although steganography is not a new discipline, it has become increasingly important in today's digital world ...

Adaptive Image Steganalysis

Multimedia Tools and Applications, 2017
Image steganography is the process of sending messages secretly by hiding the message in AN image content. Although steganography hides information in any kinds of digital mediums, digital images are the most popular carrier because of the frequency of usage in the internet.
