Audio forensic examination

IEEE Signal Processing Magazine, 2009
The field of audio forensics involves many topics familiar to the general audio digital signal processing (DSP) community, such as speech recognition, talker identification, and signal quality enhancement. There is potentially much to be gained by applying modern DSP theory to problems of interest to the forensics community, and this article is written

Digital audio forensics using background noise

2010 IEEE International Conference on Multimedia and Expo, 2010
This paper presents a new audio forensics method based on background noise in the audio signals. The traditional speech enhancement algorithms improve the quality of speech signals, however, existing methods leave traces of speech in the removed noise. Estimated noise using these existing methods contains traces of speech signal, also known as leakage ...

Digital audio forensics

Proceedings of the 9th workshop on Multimedia & security - MM&Sec '07, 2007
In this paper a first approach for digital media forensics is presented to determine the used microphones and the environments of recorded digital audio samples by using known audio steganalysis features. Our first evaluation is based on a limited exemplary test set of 10 different audio reference signals recorded as mono audio data by four microphones

Audio forensic marking for music streaming service

2013 International Conference on ICT Convergence (ICTC), 2013
In this paper, we propose an audio forensic marking scheme suitable for music streaming service. To support the real time forensic marking embedding, our scheme consists of preparation stage and composition stage. We verified performance, robustness, and imperceptibility of the proposed scheme through some experiments.

Audio forensics using acoustic environment traces

2012 IEEE Statistical Signal Processing Workshop (SSP), 2012
Acoustic environment leaves its fingerprint in the audio recording captured in it. Acoustic reverberation and background noise are generally used to characterize an acoustic environment. Acoustic reverberation depends on the shape and the composition of a room, whereas, the background noise can be modeled using a dynamical random process ...

A novel audio forensic data-set for digital multimedia forensics

Australian Journal of Forensic Sciences, 2017
Today, digital multimedia (audio, video, images) is a common evidential source in litigation and criminal justice proceedings, and, not surprisingly, multimedia forensics is an active research area. One particular challenge faced by multimedia forensic researchers is the lack of a comprehensive and publicly available data-set for evaluating existing ...

GMM-based audio codec detection with application in forensics

2015 38th International Conference on Telecommunications and Signal Processing (TSP), 2015
Reliable detection of previous compression in audio is a sensible subject of interest for both forensic analysts and audiophiles. The former use could lead for audio authentication, while the latter may be able to detect simulated high quality of audio.

Band Energy Difference for Source Attribution in Audio Forensics

IEEE Transactions on Information Forensics and Security, 2018
Digital audio recordings are one of the key types of evidence used in law enforcement proceedings. As a result, the development of reliable techniques for forensic analysis of such recordings is of principal importance. One of the main problems in forensic analysis is source attribution, i.e., verifying whether a certain recording was acquired with a ...

Overview of Audio Forensics

2010
Audio forensics applies the tools and techniques of audio engineering and digital signal processing to study audio data as part of a legal proceeding or an official investigation of some kind. This chapter summarizes the principal audio forensic tasks, including authentication, enhancement, and interpretation.

Audio watermarking forensics: detecting malicious re-embedding

SPIE Proceedings, 2010
Digital watermarking has become a widely used security technology in the domain of digital rights management and copyright protection as well as in other applications. In this work, we show recent results regarding a particular security attack: Embedding a new message in a previously watermarked cover using the same key as the original message ...
