In order to solve the problem that it is difficult to extract the watermark when the carried audio
is subjected to malicious attacks, audio watermarking algorithm based on spectrum …

When digital images are shared over an open access network such as the internet,
facebook, WhatsApp, and other social media, then the security of these images are required …

In this paper, we present a novel scheme for enhancing the security of speech information in
communication systems. We build a hybridization of three approaches: Chaotic logistic and …

Robustness, imperceptibility and embedding capacity are the preliminary requirements of
any digital audio watermarking technique. However, research has concluded that these …

How to effectively resist synchronization attacks is the most challenging topic in the research
of robust watermarking algorithms. A robust and blind audio watermarking algorithm for …

How to improve the robustness to resist attacks and how to adaptively match the key
parameters of the watermarking algorithm with the performance requirements to achieve the …

In this paper, we propose a novel watermarking method in order to enhance the security in
biometric voice/speech transmission systems basing on sub-sampling, discrete cosine …

With the increased use of the Internet in everyday life, data transmission over the internet
needs to be secure, so it necessitates the adoption of watermarking. Watermarking is the …

In this book, we have detailed our Image Watermarking Techniques which are proposed in
the literature. The first technique detailed in Chap. 1, is entitled Image Watermarking Using …

Hybrid Watermarking Approach is one of the trending approaches in the field of information
security. Watermarking has a variety of applications to ensure data authentication, security …
