Performance Evaluation of Enhanced Least Significant Bit Audio Steganographic Model for Secure Electronic Voting

Abstract

This paper presents performance evaluation of an enhanced Least Significant Bit (LSB) audio steganographic model for secure electronic voting. The enhancement on the traditional LSB audio steganographic technique on the electronic vote was achieved through the hidden of secret information from fourth bit to sixth bit position. The sampled votes were digitally signed to ensure the integrity of the casted votes. The model was evaluated objectively using three quantitative metrics: Embedding capacity of the stego audio file, Mean Square Error (MSE) and Peak Signal to Noise Ratio (PSNR) of the cover and stego audio. The results of the quantitative evaluation of the model showed that the model was robust and imperceptible for the delivery of transparent and credible secure e-voting of high electoral integrity and confidentiality in developing countries of significant digital divide.
