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.

An Efficient Network Intrusion Detection and Classification System

Iftikhar Ahmad et al.

Summary: Intrusion detection in computer networks is important for communication and security domains, but remains a challenging task. This paper compares multiple techniques to develop a network intrusion detection system and proposes an AdaBoost-based approach. Experimental results show that the proposed method effectively detects different forms of network intrusions and achieves 99.3% accuracy on the UNSW-NB15 dataset.

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.
