DWT‐SVD Based Watermarking for High‐Resolution Medical Holographic Images
Complexity, Volume 2022, Issue 1, 2022., 2022 Watermarking is one of the most common techniques used to protect data’s authenticity, integrity, and security. The obfuscation in the frequency domain used in the watermarking method makes the watermarking stronger than the obfuscation in the spatial domain.

Fully spatial and SNR scalable, SPIHT-based image coding for transmission over heterogenous networks
Journal of Telecommunications and Information Technology, 2003 This paper presents a fully scalable image coding scheme based on the set partitioning in hierarchical trees (SPIHT) algorithm. The proposed algorithm, called fully scalable SPIHT (FS-SPIHT), adds the spatial scalability feature to the SPIHT algorithm ...

A Metaheuristic Approach to Secure Multimedia Big Data for IoT‐Based Smart City Applications
Wireless Communications and Mobile Computing, Volume 2021, Issue 1, 2021., 2021 Media streaming falls into the category of Big Data. Regardless of the video duration, an enormous amount of information is encoded in accordance with standardized algorithms of videos. In the transmission of videos, the intended recipient is allowed to receive a copy of the broadcasted video; however, the adversary also has access to it which poses a ...
