The student (Amir Abdul Baki Badr) received his master's degree from the Department of Computer Sciences / University of Technology for his thesis (Adding a Digital Audio Watermark Using Hilbert-Huang Transform). This thesis proposed two digital watermark algorithms to achieve copyright protection as well Documentation of audio content. The first proposal proposes a safe, adaptive watermark algorithm based on the experimental analysis method. The second proposal proposes a strong, secure audio watermark to protect copyrights based on hybrid transformations. This was on Thursday, 25/1/2018, and on the discussion hall in the department. The discussion committee was composed of Dr. Abdul Amir Abdullah Karim and Dr. Alaa Kazem Farhan of the University of Technology / Computer Sciences Department.
