But most of existing instant messaging systems have severe security problems, people want to retain their privacy and communication should not copy or modified by a third party.This thesis presents the design and implementation of a secure instant messaging system. It achieved security objectives such as data integrity and confidentiality through encryption.

Abstract:

The recognition process is an important task in many applications of computer image analysis based on color or texture features. In this research, a texture recognition system has been introduced.The first stage
is called the preprocessing stage. In this stage, a number of color transforms have been done on the training images to produce a set of bands (R, G, B, Gray, Y, I, Q, H, S, and V bands). Fromthese bands, two
