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

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 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.

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.

Digital audio forensics using background noise
2010 IEEE International Conference on Multimedia and Expo, 2010This 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 ...

Audio Forensics Evaluation (SAFE) Challenge
Proceedings of the ACM Workshop on Information Hiding and Multimedia SecurityThe increasing realism of synthetic speech generated by advanced text-to-speech (TTS) models, coupled with post-processing and laundering techniques, presents a significant challenge for audio forensic detection. In this paper, we introduce the SAFE (Synthetic Audio Forensics Evaluation) Challenge, a fully blind evaluation framework designed to ...

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 ...

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 ...
