STONE: Secret-data Transmission On Novelty Encryption

With the increasing growth of the data innovation area, information security has become a critical concern and significant feature. In several confidential applications, it is possible to break the security message. As a result, secret message communication technology is required to avoid message breaches. Steganography is the method of embedding any hidden data or information into a cover file, such as a picture, text, audio, or video. The majority of hidden information concealment methods in the current decade make use of multimedia artefacts. With an in-depth literature review, this paper elaborates on two-stage multimedia steganography. In the first stage, the secret message is implanted in the original sound from a multimedia file, resulting in stego-audio. The second stage embeds stego audio with the video frames once more. To incorporate the hidden audio, the audio steganography employs the 3-bit LSB encryption technique. To the recipient side, the processed video with stego-audio is sent. The audio is derived from the video stream in the receiver part. A concealed message is separated from stego audio using the 3-bit LSB decryption technique. PSNR, SSIM, and MSE metrics are used to evaluate the suggested algorithm's performance. This well-thought-out method has yielded encouraging results.
