Hiding Capacity and Audio Steganography Model Based on LSB in Temporal Domain

Abstract

Background: Researchers for data hiding using the various encrypting techniques to improve the security of transmission of confidential information through an unsecured channel have been carried out. Methods: In this paper, a new higher recognition Least Significant Bit (LSB) audio data concealment is suggested in this framework. This technique is used to embed the hidden audio into cover audio of the same size. Results: The altered speech file appears as the original carrier file after embedding the secret message. This model strengthens hiding capability and audio quality. Conclusion: The strategy outperforms similar studies by enhancing hiding capability up to 30% and preserving stego audio transparency with the SNR value at 72.2 and SDG at 4.8.
