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 ...

Digital multimedia audio forensics: past, present and future
Multimedia Tools and Applications, 2017Digital audio forensics is used for a variety of applications ranging from authenticating audio files to link an audio recording to the acquisition device (e.g., microphone), and also linking to the acoustic environment in which the audio recording was made, and identifying traces of coding or transcoding.

A Forensics System for Live-Audio Watermarking
2020 International Symposium on Electronics and Telecommunications (ISETC), 2020A common problem in audio forensics is the difficulty to authenticate an audio recording. You can have an argument against any audio probe. In this paper we propose a system that can take audio probes which can be used with success in a court. The recording will be bulletproof due to the use of a reference protocol based on an external entity, the ...

A cloud-oriented integrity verification system for audio forensics
Computers and Electrical Engineering, 2019Abstract Integrity analysis is an important task in the field of audio forensics. Its aim is to verify if an evidence (i.e. audio recording) has been manipulated or not. With the aim of providing a solution for the chain of custody, we propose a system that encompasses capture module, the hash value of the audio recording, cloud storage and integrity

Forensic audio watermark detection
SPIE Proceedings, 2012Digital audio watermarking detection is often computational complex and requires at least as much audio information as required to embed a complete watermark. In some applications, especially real-time monitoring, this is an important drawback. The reason for this is the usage of sync sequences at the beginning of the watermark, allowing a decision ...

Audio forensics from acoustic reverberation
2010 IEEE International Conference on Acoustics, Speech and Signal Processing, 2010An audio recording is subject to a number of possible distortions and artifacts. For example, the persistence of sound, due to multiple reflections from various surfaces in a room, causes temporal and spectral smearing of the recorded sound. This distortion is referred to as audio reverberation time.

Audio recorder forensic identification in 21 audio recorders
2015 IEEE International Conference on Progress in Informatics and Computing (PIC), 2015Audio recorder forensic identification is to determine originating devices of questioned audio recordings. In this paper, statistical features both in time and frequency domains were studied and were used to represent and encode device-related information.
