Research ArticleOpen accessIn the abstractAn Optimization Approach for Selecting Blocks of Embedding Process in Robust Watermarking SystemAbabneh M.F. Mohammad, Naseem M. AsadThis study, discusses several kinds of attacks that may meet the watermarked image such as JPEG compression, Gaussian noise and median filter. The study introduces an approach capable of selecting the optimal blocks in cover image to be used in embedding process. Also, in this study, we propose a technique in robust digital watermarking system looking for finding a relation … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 7,175 accessesView PDF Cite

Research ArticleOpen accessIn the abstractIncreasing Effectiveness of IDS to Improve Security in IntranetUmesh Kumar Singh, A. K. Ramani, Narendra S. Chaudhari, Vandana GuptaToday Intrusion Detection Systems (IDS) are becoming one of the most important tools for intranet security. Research regarding Intrusion Detection Systems (IDSs) has become more active with the recent increases in illegal accesses to computer systems. Many researchers focus only on the techniques or mechanisms for detecting intrusions automatically, without considering the security of IDSs themselves. When an intruder attacks … …American Journal of Applied Sciences, Vol. 2, Issue 6 · 30 Jun 2005 · 7,148 accessesView PDF Cite

Research ArticleOpen accessIn the abstractChemical and Biological Warfare: Should Rapid Detection Techniques Be Researched To Dissuade Usage? A ReviewMark R. Hurst, Ebtisam WilkinsChemistry, microbiology and genetic engineering have opened new doorways for the human race to propel itself to a better future. However, there is a darker side to Bioengineering. One element of this is the manufacture and proliferation of biological and chemical weapons. It is clearly in the interest of humankind to prevent the future use of such weapons of mass … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 6,865 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAn Investigation into the Use of the Least Significant Bit Substitution Technique in Digital WatermarkingKevin Curran, Xuelong Xi, Roisin ClarkeDigital imaging companies lose revenue each year to people who are illegally copying and using their images. One prevention mechanism is to digitally encode images making it difficult for others to copy. This could be done using digital fingerprinting or simply adding a visible watermark. The information is hidden in a way that should not attract attention, but make it … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 7,471 accessesView PDF Cite
