A Novel Digital Audio Encryption and Forensics Watermarking Scheme
IEEE AccessThere are a large amount of audio signals stored in third-party storage centers. To improve the privacy and security of audio signals, a digital audio encryption and forensics watermarking scheme is proposed. We defined the signal energy ratio feature of audio signals and designed the embedding method by quantifying the feature, aiming to improve the ...

International Journal of Mental Health Nursing, Volume 35, Issue 3, June 2026.ABSTRACT Safewards is implemented internationally to prevent conflict and containment in psychiatric settings. Although evaluations generally show a reduction in such incidents, effects vary across studies. A key limitation is the absence of a valid and robust measure of implementation fidelity to indicate how closely Safewards is implemented as ...

Secure Audio Forensic Marking Alogrithm Using 2D Barcode in DWT-DFRNT Domain
International Journal of Distributed Sensor Networks, 2014 We created a robust and secure forensic marking algorithm through the process of hiding information in a two-dimensional (2D) barcode and embedding it into the discrete wavelet transformation-discrete fractional random transformation (DWT-DFRNT) domain ...

Acoustic Environment Identification and Its Applications to Audio Forensics
IEEE Transactions on Information Forensics and Security, 2013 An audio recording is subject to a number of possible distortions and artifacts. Consider, for example, artifacts due to acoustic reverberation and background noise. The acoustic reverberation depends on the shape and the composition of a room, and it causes temporal and spectral smearing of the recorded sound.

Detecting Audio Copy-Move Forgeries on Mel Spectrograms via Hybrid Keypoint Features
Applied SciencesWith the widespread use of audio editing software and artificial intelligence, it has become very easy to forge audio files. One type of these forgeries is copy-move forgery, which is achieved by copying a segment from an audio file and placing it in a ...
