An integer wavelet transform (IWT) based image steganography technique is proposed to
prevail the embedding capacity constraints in this domain. Quotient value differencing (QVD) …

Reversible data hiding (RDH) for digital images is a widely studied steganography that
ensures the carrier image can be restored without distortion. Due to the popularity of Internet …

Reversible data hiding (RDH) techniques can extract the complete secret information and
recover the original 3D models. However, modifying vertices in the spatial domain to embed …

With the tremendous rise in multimedia output over the last ten years, image encryption has
grown in importance as a component of information security. It is challenging to secure …

In the previous decade, biometrics referred to the automatic recognition of persons based on
their physiological or behavioural traits but unimodal biometrics have their limitations. Due to …

In this paper, we introduce a high-speed and area-efficient hardware design for a novel
modulus-based image steganographic scheme, specifically targeting constrained-area …

Thanks to its intuitive design, the picture hosting platform is quickly gaining users, although
some worry about their privacy. Unfortunately, visual privacy protection solutions are …
