A Review of Security in Adaptive Video Streaming

The proliferation of adaptive video streaming services has revolutionized the way multimedia content is delivered over the Internet. While these services enhance user experience by dynamically adjusting video quality based on network conditions, they also introduce new security challenges. This review paper provides a comprehensive examination of the security aspects associated with adaptive video streaming technologies. The paper begins by presenting an overview of adaptive video streaming architectures and protocols, emphasizing their role in optimizing video delivery across diverse network environments. Subsequently, it delves into the vulnerabilities inherent in these systems, covering issues such as content piracy, privacy concerns, and the potential for various types of attacks, including man-in-the-middle attacks, DDoS attacks, and buffer overflow attacks. A significant portion of the review is dedicated to discussing existing security mechanisms and countermeasures employed in the context of adaptive video streaming. This includes encryption techniques, authentication protocols, and digital rights management (DRM) solutions. The strengths and limitations of these measures are critically assessed, with a focus on their effectiveness in mitigating the identified security threats. Furthermore, the paper explores emerging trends and technologies in the realm of security for adaptive video streaming. This includes the integration of artificial intelligence and machine learning for anomaly detection, blockchain for secure content distribution, and the adoption of watermarking techniques to trace illicit redistribution of content. In conclusion, this review paper synthesizes current research findings and industry practices related to security in adaptive video streaming. By highlighting the challenges and opportunities in this dynamic field, it aims to provide researchers, practitioners, and policymakers with valuable insights to enhance the security posture of adaptive video streaming systems and contribute to the ongoing evolution of secure multimedia content delivery over the Internet
