ABSTRACTThis paper presents a method of hiding the text message watermark into audio. This hiding technique is called amplitude modification in low bit encoding. The message embedded into higher LSB layers to increase the robustness. The technique is implemented in matlab since it is a language for data analysis and numerical computation. This proposed scheme includes dynamic coding approach fo...

The issue of important information hiding preoccupied the minds of many people especially in business, military and political fields due to the secrecy of their information. Thus, there were always secret means and methods that were pursued to send such information. Later on the spread of internet, information can be sent easily and quickly .Still, at the same time the sent data was easily inte...

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.

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...
