Improved Audio Steganalytic Feature and Its Applications in Audio Forensics
ACM Transactions on Multimedia Computing, Communications, and Applications, 2018Digital multimedia steganalysis has attracted wide attention over the past decade. Currently, there are many algorithms for detecting image steganography. However, little research has been devoted to audio steganalysis. Since the statistical properties of image and audio files are quite different, features that are effective in image steganalysis may ...

Authenticity verification of audio signals based on fragile watermarking for audio forensics
Expert Systems with Applications, 2018Abstract This paper presents a new fragile watermarking method for digital audio authenticity for audio forensics purposes. The aim is to verify if an audio proof has been tampered and to locate the segments where the signal was modified. Our proposal is based on an embedding process of a text that is encoded through OVSF (Orthogonal Variable ...
