Climatizing the Detection of Secret Data and Sterling Data Transmission in Steganography

Abstract

In the last decades, information security has become a crucial issue, as the data innovation field is growing rapidly. In military applications, there is a possibility of breaking the security message. Hence there is a need for secrete message communication technology to prevent message breaching. Steganography is the process of embedding any secret message or information like image, text, audio, and video with the original cover file. Today, most secret information hiding systems use multimedia objects. This paper proposes two-stage multimedia steganography. In the first stage, the secrete message is embedded in the extracted audio from a multimedia video file. In the second stage, stego audio is again embedded with the video frames. The audio steganography uses the Least Significant Bit (LSB) substitution algorithm to embed the secrete audio, called stego audio. This is then embedded with the video frames. The processed video is transmitted to the receiver side. In the receiver section, the audio is extracted from the video stream. The 4-bit LSB decryption algorithm separates a secrete message from stego audio. The evaluating performance parameters of the proposed algorithm are PSNR, SSIM, and MSE metrics. This proposed algorithm is achieved promising results.
