Image compression involves reducing the size of image data files, while retaining necessary information. Compression is a necessary and essential method for creating image files with manageable and transmittable sizes. There have been many types of compression algorithms developed.
Color images have the potential to convey more information than a monochrome or black and white images. Each pixel for a true color image is stored as values of red, green, and blue. However, the RGB color model is not an efficient representation for compression task because there is significant correlation between RGB color components. Therefore, for compression, luminance-chrominance representations (such as YIQ) is implemented.
The expansion of computer networks and the use of Internet in every side of our life, and the importance of Computer and Network security, , computer aided learning Security System is utilized to make many security attacks and services easier to be applied and understood by students and other people.The proposed system will mainly be divided into two parts, Application mode and Documentation mode. In the two modes, the system will be in two parts: Attack and Defense. In the Attack and Defense, the well known security tools will be covered.
