A Low-throughput Wavelet-based Steganography Audio Scheme

TL;DR

This paper proposes a novel wavelet-based audio steganography scheme that combines cryptographic encryption with wavelet analysis, using two secret keys for enhanced security, though it currently has low throughput.

Contribution

It introduces a new steganography method integrating cryptographic encryption with wavelet analysis and dual keys, advancing security in audio data hiding.

Findings

Preliminary scheme demonstrating concept feasibility

Uses two secret keys for encryption and embedding

Focuses on security rather than high throughput

Abstract

This paper presents the preliminary of a novel scheme of steganography, and introduces the idea of combining two secret keys in the operation. The first secret key encrypts the text using a standard cryptographic scheme (e.g. IDEA, SAFER+, etc.) prior to the wavelet audio decomposition. The way in which the cipher text is embedded in the file requires another key, namely a stego-key, which is associated with features of the audio wavelet analysis.
