High capacity and high imperceptibility are the primary targets for ideal image
steganography. For the traditional transform-based schemes, the main challenge is to …

In this paper, an image steganography method is proposed to overcome the limitations
associated with the most existing image steganography methods based on either spatial …

The big data era calls for image steganography with large embedding capacity and good
image quality. Previous methods described in the literature pay more attention to image …

This paper introduces a high capacity image hiding scheme with enhanced stego image
quality. This new hiding scheme utilizes a multiscale Laplacian pyramid of the cover image …

Posting images on social network platforms is happening everywhere and every single
second. Thus, the communication channels offered by various social networks have a great …

Hiding sensitive information in a host image (or 2D signal) is a challenging task. Several
image steganography techniques have been proposed in recent years, which either have …

The importance of image steganography is unquestionable in the field of secure multimedia
communication. Imperceptibility and high payload capacity are some of the crucial parts of …

Data hiding called steganography is a security technique to protect secret data throughout
the transmission from malicious attackers. The purposes of steganography are to obtain …

Steganography is the art and science of hiding data in different media such as texts, audios,
images, and videos. Data hiding techniques are generally divided into two groups: spatial …

Presently, the design and development of an effective image steganography system are
facing several challenges including the low capacity, poor robustness and imperceptibility …
