The student Haidar Mohammed Alwan received his master's degree from the Department of Computer Sciences / University of Technology for his thesis entitled (A Proposed Algorithm to Decrease False Alarm in Intrusion Detection System). In this thesis the proposed system is to use the equations of the Bezier Curve to select the locations of the images from the secret image and then use The logical operation (XOR) between the site content (pixel data) selected according to the Bezier equations and the key and output of this process is hidden in the N-images of the cover images. The proposed masking system gives high security and can hide a large size image in a small image collection. The quality of Stego images is evaluated after data is hidden using the PSNR and MSE evaluation criteria. The results show that this method is more accurate than the traditional method. In addition, the use of more than one image envelope instead of one envelope to increase the load of hidden data will further complicate the end The third to recover the hidden image, because getting one or two or three of the cover images will not enable him to obtain the secret image.

This was on Monday 23/4/2018 and on the discussion hall in the department. The discussion committee was composed of (Dr. Mithad Emad El-Din Abdel Moneim and Dr. Maysaa' Abdel Khader) from the University of Technology / Computer Sciences Department And Dr. Amer Siddiq Mustafa from Imam Sadeq University, Faculty of Computer Technology, in the presence of the student supervisors (Dr. Abdul Amir Abdul Karim and Dr. Abdul Mohsin Jabir Abdul Hussain).
