Image Steganography Method for Securing Multiple Images Using LSB–GA

Abstract

Image steganography is renowned for its exibility and frequency in the current scenario. This article presents a combination of LSB (Least Signi cant Bit technique) and GA (Genetic Algorithm) to hide various forms of data -text and images. A novel combination of steganography techniques is used to transmit complete secret data. Also, multiple color images are embedded in a single color image, showing increased secret data holding capacity. Furthermore, the application of GA assures increased security. The excellence of the stego image and retrieved images are evaluated in terms of Peak Signal to Noise Ratio (PSNR), Structural Similarity Index Metric (SSIM), Correlation coe cient, and Bit Error Rate (BER). Hence, this article is targeted to transmit multiple color images with no loss and improved security using GA and we achieved SSIM between 0.996 to 1.
