Existing techniques for reversible hiding of data in audio signals are so fragile that no data
can be extracted from a modified stego audio signal. The present study proposes a …

Recently, a technique that uses quantization index modulation and amplitude expansion
has been proposed for reversible and robust audio watermarking. However, when applied to …

Reversible data hiding is a technique whereby hidden data are embedded in host data in
such a way that the host data consistency is perfectly preserved and the host data are …

Robust audio watermarking generally requires three main traits: robustness against
modifications inherent to the medium and/or intentional attacks, perceptual transparency …

Being reversible, the watermarking information embedded in audio signals can be extracted
while the original audio data can achieve lossless recovery. Currently, the few reversible …

In this paper, a generalized difference expansion based reversible audio data hiding
algorithm is proposed and a recommended application is introduced. The proposed …

This paper aims to explore an alternative reversible digital watermarking solution to
guarantee the integrity of and detect tampering with data of probative importance. Since the …

A digital watermark can be seen as an information channel, which is hidden in a cover
signal. It is usually designed to be imperceptible to human observers. Although …

Robust and reversible watermarking is a potential technique in many sensitive applications,
such as lossless audio or medical image systems. This paper presents a novel robust …

The leakage of medical audio data in telemedicine seriously violates the privacy of patients.
In order to avoid the leakage of patient information in telemedicine, a two-stage reversible …
