A stack-based chaotic algorithm for encryption of colored images

In this paper, a new method is presented for encryption of colored images. This method is based on using stack data structure and chaos which make the image encryption algorithm more efficient and robust. In the proposed algorithm, a series of data whose range is between 0 and 3 is generated using chaotic logistic system. Then, the original image is divided into four subimages, and these four i...

A Cabinet of Medical Curiousities

Ryan's theory is that a virus behaves as an aggressive symbiont in that it can con-comitantly live within a host (enjoying protection and employing its replicative facility) without causing disease and benefit the host by designedly causing disease in rival species. He uses this concept to introduce the idea that the emergence of viruses is inevitable when one species imposes on the habitat of ...

Column: File Cabinet Forensics

Reverse Engineering is the traditional bread-and-butter of digital forensics research. Companies like Microsoft and Apple deliver computational artifacts (operating systems, applications and phones) to the commercial market. These artifacts are bought and used by billions. Some have evil intent, and (if society is lucky), the computers end up in the hands of law enforcement. Unfortunately the o...
