Lightweight Steganography Technique in The Internet of Things: A survey

Abstract

In the context of the Internet of Things (IoT), lightweight steganography provides a revolutionary combination of technology and security, where data concealment meets the efficiency requirements of IoT devices. Lightweight steganography, as opposed to conventional steganographic methods, focuses on concealing information inside digital content while using the least amount of computer resources and energy. Secure data transfer is essential in the IoT world because linked devices may communicate with one another without interruption. IoT devices may communicate private data discreetly while conserving system resources, thanks to the elegant approach offered by lightweight steganography. This novel method makes use of complex algorithms that gently change data packets, turning them into bearers of hidden information without raising any red flags. The secrecy of IoT ecosystems is strengthened by lightweight steganography's easy integration of covert communication channels. In addition to improving data security, this technology also optimizes bandwidth usage and increases device battery life. A future when linked devices may transmit information safely, effectively, and surreptitiously is predicted as the IoT environment develops. This would usher in a period of unmatched data security and resource optimization.
