A Novel Approach for Image Steganography in Spatial Domain

TL;DR

This paper introduces a new spatial domain image steganography method that embeds three bits per pixel using Lucas numbers, achieving higher capacity, better image quality, and improved undetectability.

Contribution

It proposes a novel embedding technique utilizing Lucas numbers and restricts modifications to one bit plane, enhancing capacity and security over existing methods.

Findings

Higher embedding capacity with three bits per pixel

Improved peak signal-to-noise ratio (PSNR)

Enhanced resistance to steganalysis detection

Abstract

This paper presents a new approach for hiding information in digital image in spatial domain. In this approach three bits of message is embedded in a pixel using Lucas number system but only one bit plane is allowed for alternation. The experimental results show that the proposed method has the larger capacity of embedding data, high peak signal to noise ratio compared to existing methods and is hardly detectable for steganolysis algorithm.
