ABSTRACT = {Steganography aims to hide the messages from unauthorized persons for various 
purposes, e.g., military correspondence, financial transaction data. Securing the data during 
transmission is of utmost importance these days. The confidentiality, integrity, and 
availability of the data are at risk because of the emerging technologies and complexity in 
software applications, and therefore, there is a need to secure such systems and data. There 
are various methodologies to deal with security issues when utilizing an open system like 
the Internet. This research proposes a new technique in steganography within RGB shading 
space to achieve enhanced security compared with existing systems. We evaluate our 
approach with the help of diverse image quality evaluation techniques including MSE 
(Mean Square Error), RMSE (Root Mean Square Error), PSNR (Peak Signal-to-Noise 
Ratio), MAE (Mean Absolute Error), NCC (Normalized Cross-Correlation) and SSIM 
(Structural Similarity Index). Our experimental results demonstrate improved strength, 
intangibility, and security when contrasted with existing techniques and vindicate the 
effectiveness of this exploration work. The proposed approach achieved a 3.6701% average 
higher score for PSNR Correlation than the next best existing approach. Moreover, in 
PSNR with a variable amount of cipher embedded in the same images of the same 
dimensions, the proposed approach attained a 5.22% better score. Embedding the same size 
of cipher in images of different size resulted a 3.56% better score.},
