Abstract

The development in information technology has made digital images pervasive in many domains of work. To benefit the pervasiveness of the digital images, researchers use the pixels of the digital images to hide and carry secret data, known as steganography, confidentially. The existing works in steganography have shown weaknesses in conserving the quality of an image used to host the secret data when considering the large payloads. To mitigate this, this paper proposes a new steganographic scheme to improve the quality of the image carrying the secret data, evaluated as peak signal-to-noise ratio (PSNR) quantified in decibels (dB) by using the expansion between the pixels in the neighbourhood in a customized manner. The experimentations, which yielded higher imperceptibility of the hidden data, have been done with random bits of secret data with sizes ranging from 1 to 100 kilobits. With our results, we obtained a PSNR of 62.478 dB, which is superior to the ones in the existing works.
