Data hiding in speech signal using steganography and encryption
This addresses data privacy and security for users transmitting sensitive information, but it appears incremental as it builds on existing steganography and encryption techniques.
The paper tackles the problem of secure data transmission by proposing a method for hiding a ten-digit number within speech signals using steganography and encryption, with simulation results showing better performance compared to existing approaches based on metrics like PSNR, MSE, SSIM, and bit-error rate.
Data privacy and data security are always on highest priority in the world. We need a reliable method to encrypt the data so that it reaches the destination safely. Encryption is a simple yet effective way to protect our data while transmitting it to a destination. The proposed method has state of art technology of steganography and encryption. This paper puts forward a different approach for data hiding in speech signals. A ten-digit number within speech signal using audio steganography and encrypting it with a unique key for better security. At the receiver end the same unique key is used to decrypt the received signal and then hidden numbers are extracted. The proposed approach performance can be evaluated by PSNR, MSE, SSIM and bit-error rate. The simulation results give better performance compared to existing approach.
