Audio forensics using acoustic environment traces
2012 IEEE Statistical Signal Processing Workshop (SSP), 2012Acoustic 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, 2017Today, 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), 2015Reliable 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.

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 ...

Band Energy Difference for Source Attribution in Audio Forensics
IEEE Transactions on Information Forensics and Security, 2018Digital 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 ...

Audio watermarking forensics: detecting malicious re-embedding
SPIE Proceedings, 2010Digital 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 ...

The ability to perform audio forensic analysis hinges on the availability of audio recordings made outside the confines of a recording studio. The first portable recorders using magnetic tape appeared in the 1950s, and soon these devices were used to obtain clandestine recordings of interviews and wiretaps, as well as to record interrogations and ...

Verifier-tuple for audio-forensic to determine speaker environment
Proceedings of the 7th workshop on Multimedia and security, 2005In this paper a new concept for audio classification and analysis is presented to determine the authenticity of the speaker's environment. The overall concept's characteristic is determined through an introduced Verifier-Tuple, which enables a detailed analysis of every kind of media. The purpose, the practise as well as the need of this Verifier-Tuple

A cloud-oriented integrity verification system for audio forensics
Computers & 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
