The teaching in the Department of Computer Science, Assistant Professor Dr. Maysa Abd Ali, published her research entitled "Encrypting the secret message and hiding it within the framework of the video using the magic box" at the Fourth International Conference on Mathematical Sciences The shrine is for the period from (17-21 / June / 2020) at the Turkish University of Maltepe in Istanbul. The aim of the research is to hide the big data in the video frame, where a new method has been proposed to hide the secret texts of large size in the video frame with efficiency and high accuracy in a way that consists of three main stages. Hiding secret texts in a video frame using the secret key or magic square. The results obtained were good at hiding the large text without sensitivity by the attacker by applying the standards in each video frame such as PSNR, MSE, Entropy, graph and correlation coefficient.
