Volume 11
Abstract In recent years, the integration of digital signal processing with information security technologies has intensified interest in steganography and its counterpart, stegoanalysis. Owing to their continuous and widely distributed nature, audio signals represent an excellent medium for both information hiding and detection research. This study presents a robust compressionbased stegoanalysis method designed to automatically detect hidden data within WAVE audio files through statistical variations in the least significant bits (LSBs). The proposed algorithm operates by comparing the compression ratios of original and potentially modified audio files, allowing the detection of concealed information with high accuracy and efficiency. Experimental validation across various datasets—comprising speech, classical, and dynamic music—demonstrates that the WinZIP® 14.5 compression approach outperforms WinRAR® 5.50 in sensitivity and precision. The results confirm that the proposed model is computationally efficient, scalable, and highly applicable for automated steganographic detection in digital audio systems.

Abstract: Individual recognition based on palm images is such an interesting subject. In this paper, multi-spectrums for full-palm images are considered. The spectra of 460nm and 940nm are employed. Each spectrum provides special features. That is, the spectrum of 460nm affords full-palm textures, and the spectrum of 940nm presents full-palm veins. These facilities are utilized here, where an Artificial Intelligence (AI) approach is suggested. The suggested approach consists of four Deep Learning (DL) networks. Each network is determined for a certain full-palm image, as there are four types of images: right hand full-palm textures, left hand full-palm textures, right-hand full-palm veins, and left-hand fullpalm veins. Then, the outputs are fused to provide the final recognition decision. Two datasets are exploited; both are from the Chinese Academy of Sciences Institute of Automation's (CASIA) Multi-Spectral Palmprint Image Database (version. 1.0), where full-palm images of the two spectra 460nm and 940nm are obtained. High performances are achieved after applying the suggested approach. Individual recognition based on palm images is such an interesting subject.
