Calibration and higher order statistics (HOS) are standard components of many image steganalysis systems. These techniques have not yet found adequate attention in audio steganalysis context. Specifically, most of current works are either non-calibrated or only based on noise removal approach. This paper aims to fill these gaps by proposing a new set of calibrated features based on re-embedding...

Steganography meaning covered writing. Steganography includes the concealment of information within computer files [1]. In other words, it is the Secret communication by hiding the existence of message. In this paper, we will refer to cover image, to indicate the images that do not yet contain a secret message, while we will refer to stego images, to indicate an image with an embedded secret me...

The vas t majority of crimes commit ted against city, suburban, and rural residents in 1983 occurred in the general a r e a where the victims lived. Xowever, suburban dwellers were more likely t o be victims of cr imes of violence within the ci ty limits of the cen t ra l c i t ies of their metropolitan areas (12%) than were ci ty dwellers t o become victims in the suburban a reas surrounding t...

The processing of Navon figures (Navon, 1977), i.e., hierarchical letter stimuli, has been studied in experimental settings for many years. In particular, they have been studied in the context of visual hemifield studies and yielded an interaction between hemifield and whether a target is at the local or global level, with a right hemisphere advantage for the global level, and a left hemisphere...

We present three attacks on the Prime Power RSA with modulus N = pq. In the first attack, we consider a public exponent e satisfying an equation ex − φ(N)y = z where φ(N) = pr−1(p − 1)(q − 1). We show that one can factor N if the parameters |x| and |z| satisfy |xz| < N r(r−1) (r+1)2 thereby extending the recent results of Sakar [16]. In the second attack, we consider two public exponents e1 and...
