数字音频篡改被动检测研究综述
Survey of Passive Detection of Digital Audio Tampering
摘要
Abstract
Passive detection of digital audio tampering refers to the technology that does not rely on any pre-embedded information to identify the authenticity of digital audio. The main research content is to determine the authenticity and integrity of digital audio. It has a wide application prospect in the fields of court forensics, news justice, intellectual prop-erty protection and so on. At present, the related reviews in the field are mainly from the point of overall framework of active and passive digital audio forensics, and they are without a systematic and comprehensive summary of passive detection of digital audio tampering. What’s more, the passive audio forensics research involving in the above reviews is with the problem of inadequate timeliness. This paper first summarizes the task model and forensics framework of digital audio tamper detection, and then divides the present digital audio tampering passive detection methods into four categories according to the tamper means, detection strategies, statistical characteristics and models used:the detection method based on tamper operation, the detection method based on the digital audio recompression, the detection method based on the recording equipment and the audio recording environment, and the detection method based on the statistical characteristics of the digital audio signal. Then it analyzes the typical algorithm and the extended means of each method, and compares the performance of different detection algorithms, then four kinds of methods for the detection of the characteristics and application scope are summarized. Finally, the main research achievements of researchers at home and abroad in digital audio tampering passive detection technology are summarized, the problems and challenges of digital audio tampering passive detection technology and the prospect of future research are put forward.关键词
