An efficient 2-step steganography technique is proposed to enhance stego image quality
and secret message un-detectability. The first step is a pre-processing algorithm that …

Most modern steganography methods focus on designing an effective cost function. To our
best knowledge, there is no related works concerned about modifying stego to enhance …

Digital steganography is becoming a common tool for protecting sensitive communications
in various applications such as crime/terrorism prevention whereby law enforcing personals …

Classic Least Significant Bit (LSB) steganography technique is the most used technique to
hide secret information in the least significant bit of the pixels in the stego-image. This paper …

Performance measurements which characterize digital image steganography techniques
include payload capacity, stego image quality, and security (secret message detectability) …

Several problems arise among the existing LSB-based image steganographic schemes due
to distortion in a stegoimage and limited payload capacity. Thus, a proposed scheme has …

This work is concerned with implementing Steganography for images, with an improvement
in both security and image quality. The one that is implemented here is a variation of plain …

Steganography is the art and practice of communication using hidden messages. The least
significant bits (LSB) based method is the well-known type of steganography in the spatial …

To improve the stego-image quality and provide a larger embedding capacity, a novel
steganographic method based on four-pixel differencing and modulus function is presented …

In this paper, we propose a novel image steganography technique with an adaptive
embedding scheme that combines the methods of edge detection and hybrid Hamming …
