Abstract : Secure information transmission between the two parties is essential because of rapid increase of digital communication and information technology. Steganography a data hiding approach can be used to securely transmit data over the internet. In this paper we focus on hiding secret data in the selected speech parameters of GSM communication through Quantization using Predictive Coding hiding method. We have used two parameters LPC coefficients and RPE pulse parameters to hide the secret so that the quality of the signal is not affected. The objective is to analyze the quality of the signal after embedding with different capacity. Experimental results showed that with 25 percent embedding capacity in RPE pulse parameter the quality of the signal in terms of SNR, MSE and MOS were found to be above 26, 0.01, and 4. Irrespective of any embedding rate in LPC coefficients SNR, MSE and MOS are found to be above 28dB, 0.001 and 4 respectively. © 2018 Academic Press. All Rights Reserved.
