Privacy in internet of multimedia things

The Internet of Multimedia Things (IoMT) is a specialization of Internet of Things and has been playing a great role in the development of areas such as healthcare and smart cities. However, it is highly challenging to maintain security and privacy since it deals with sensitive multimedia data. IoMT is vulnerable to cyber threats, unauthorized access, and data breaches. This chapter reviews the recent advancements in IoMT security, including authentication methods, encryption techniques, and intrusion detection systems. Multi-factor authentication with innovative concepts such as blockchain and artificial intelligence promises decentralization of security solutions. On the other hand, lightweight protocols suitable for constrained devices and techniques like advanced encryption and emotion recognition to ensure privacy point toward scalability in security architecture. Deep learning and machine learning also played a vital part in real-time threat detection and mitigation. Though continuous improvements are going on, some of the ongoing challenges are system compatibility, security-performance trade-offs, and persistence of cyber threats.
