An Innovative Method to Enhance the Distortion Measure of Image Steganography using Advanced Encryption Standard Technique and Least Significant Bit Algorithm by Comparing with OpenCV Algorithm to Achieve Peak Signal to Noise Ratio.

Abstract

Aim: To enhance the distortion measure of encoded images in the process of Image steganography using Cryptography Algorithm for encrypting the data that is Advanced Encryption Standard(AES) with Least Significant Bit Algorithm by comparison to the OpenCV Algorithm. Methods and Materials: The two groups are OpenCV Algorithm(N=10) and Least Significant Bit Algorithm using AES(N=10). G-power is calculated for two different groups, alpha (0.05), power (80%). Results: The distortion is measured based on the Peak Signal to Noise Ratio value, where the Advanced Encryption Standard Technique using Least Significant Algorithm has the Peak Signal to Noise Ratio value of 80. The two algorithms Least Significant Bit and OpenCV Algorithms are statistically satisfied with the independent sample T-Test (???? = .001) value (p<0.05) with a confidence level of 95%. Conclusion: The distortion measure seems to be better in the Least Significant Bit Algorithm using the Advanced Encryption Standard technique when compared to the OpenCV algorithm.
