For audio watermark schemes, the method robust against desynchronization attacks based
on synchronization codes faces security challenges. In this paper, a content-based method …

In this paper, we present Jawthenticate, an earable system that authenticates a user using
audible or inaudible speech without using a microphone. This system can overcome the …

Speech tampering has brought serious problems to speech security. Information hiding
method can be used for tampering detection if it can satisfy several competitive …

In this paper, a novel semi-fragile watermarking scheme for authenticating an audio signal
based on dual-tree complex wavelet transform (DT-CWT) and discrete cosine transform …

This paper proposes an improved semi-fragile speech watermarking scheme by
quantization of linear prediction (LP) parameters, ie, the inverse sine (IS) parameters. The …

A semi-fragile watermarking scheme is proposed in this paper for detecting tampering in
speech signals. The scheme can effectively identify whether or not original signals have …

It is a challenging work to design tamper recovery schemes for digital speech signal. Briefly,
there are two problems need to be solved. One is that the signals used to tamper recovery …

This paper presents a new approach for speech signal watermarking using encrypted
watermarks. The objective of this approach is to increase the degree of security of speech …

Desynchronization attack is known as one of the most difficult attacks to resist, for it can
desynchronize the location of the watermark and hence causes incorrect watermark …

We propose a new narrowband speech watermarking scheme by replacing part of the
speech with a scaled and spectrally shaped hidden signal. Theoretically, it is proved that if a …
