Data Hiding in Speech Signal Using Steganography and Encryption

Abstract

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.

Hiding text in speech signal using K-means, LSB techniques and chaotic maps

“…Bandi and Reddy [21] suggests encrypting the secret text message and concealing it in the cover audio, using a combination of DCT coefficient and AES encryption method to provide data protection. Chowdary [22] uses a different approach for data hiding in speech signals, with a unique key which contains a ten-digit number within a speech signal for better security. Ahmed [23] suggests an algorithm using pixel value gauge technology to mask the confidential message in the cover picture's most significant bits (MSBs).…”
