In this work, an identifying and recognizing person technique is presented based on its eye’s iris. The introduce technique utilizes several image processing methods; e.g. edge detection, contour following, chain coding, Gabor filters, image normalization, feature extraction, etc. JPEG images of size 256×256 pixels are converted into grayscale form by averaging their Red, Green and Blue bands.The produced grayscale image then traced into edges and boundaries using Marr-Hildreth edge technique with an appropriate Gaussian standard deviation value (i.e. σ =3).

There is a modern type of encryption called selective encryption which depends on the choice of some sensitive areas. The encryption of these areas leads to destroy the whole file.

This research is concerned with the design and implementation of a network security monitoring system. A focus was put on monitoring the shared network resources (specifically filing system). In this work, the layers of TCP/IP suite have been studied and their roles in the process of network monitoring were defined, it was found that the internet layer can play the major role.
