A Robust 3-D Medical Watermarking Based on Wavelet Transform for Data Protection

Xiaorui Zhang et al.

Summary: In this paper, a 3D medical watermarking algorithm based on wavelet transform is proposed, which utilizes PCA transform to reduce data dimension and a BF-PSO model to find the optimal embedding parameters, achieving the optimal balance between embedding capacity and imperceptibility. Experimental results based on a standard MRI brain volume dataset in MATLAB software show that the proposed algorithm has strong robustness and minimal deformation of the 3D model after watermark embedding.

Robust Reversible Audio Watermarking Scheme for Telemedicine and Privacy Protection

Xiaorui Zhang et al.

Summary: This paper proposes a two-stage reversible robust audio watermarking algorithm for protecting medical audio data. By decomposing the audio into two independent embedding domains and embedding different watermarks, the algorithm ensures both watermark robustness and audio quality. Experimental results demonstrate that the proposed scheme has strong robustness against various signal processing operations.

Design of Latency-Aware IoT Modules in Heterogeneous Fog-Cloud Computing Networks

Syed Rizwan Hassan et al.

Summary: The increasing demand for latency-sensitive applications in Fog-based cloud computing has created challenges in meeting strict quality of service requirements. This article proposes an algorithm that effectively places application modules on network nodes while considering connection delay, processing power, and sensing data volume. Simulation results demonstrate the effectiveness of the algorithm in terms of end-to-end delay and network consumption.
