- ItemA new watermarking scheme for digital videos using DCT(Walter de Gruyter GmbH, 2022-01-01) Al-Gindy, Ahmed; Omar, Aya Al-Chikh; Mashal, Omar; Shaker, Yomna; Alhogaraty, Eslam; Moussa, SherifWith the advent of high-speed broadband Internet access, the need to protect digital videos is highly recommended. The main objective of this study is to propose an adaptive algorithm for watermarked digital videos in the frequency domain based on discrete cosine transform (DCT). The watermark signature image is embedded into the whole frame of the video. The green channel of the RGB frame is selected for the embedding process using the DCT algorithm as it shows the recommended quality of the watermarked frames. The experiment results indicate that the proposed algorithm shows robustness and high quality of the watermarked videos by testing various strength values Δ for different videos. It offers resistance against different types of attacks. © 2022 Ahmed Al-Gindy et al., published by De Gruyter.
- ItemAutoencoder-based Intrusion Detection System(Institute of Electrical and Electronics Engineers Inc., 2021) Kamalov, Firuz; Zgheib, Rita; Leung, Ho Hon; Al-Gindy, Ahmed; Moussa, SherifGiven the dependence of the modern society on networks, the importance of effective intrusion detection systems (IDS) cannot be underestimated. In this paper, we consider an autoencoder-based IDS for detecting distributed denial of service attacks (DDoS). The advantage of autoencoders over traditional machine learning methods is the ability to train on unlabeled data. As a result, autoencoders are well-suited for detecting unknown attacks. The key idea of the proposed approach is that anomalous traffic flows will have higher reconstruction loss which can be used to flag the intrusions. The results of numerical experiments show that the proposed method outperforms benchmark unsupervised algorithms in detecting DDoS attacks. © 2021 IEEE.
- ItemVirtual reality: Development of an integrated learning environment for education(International Journal of Information and Education Technology, 2020-03) Al-Gindy, Ahmed; Felix, Chema; Ahmed, Ali; Matoug, Amani; Alkhidir, MuniaThe new paradigm shift of education where learners should learn real-life scenarios and solve real-life problems has created a major challenge. Students are passive and detached and may struggle to see the relevance of what they are learning to their lives. The recent growth of emerging technologies has launched terms such as virtual reality (VR), augmented reality (AR) and mixed reality (MR) into mainstream topic. Virtual reality, an integrated, hands-on tool for learning, can play a unique role in addressing these educational challenges. The proposed research demonstrates using the knowledge of integrated disciplines with virtual reality. COSPACES and MERGE cube add-on have been used to develop a simulation platform to teach water cycle process for young kids. This type of integration develops learners’ 21st century skills to be decision makers, problem solvers, lifelong learners, creators, innovators, and to think critically in solving problems. © 2020 by the authors.
