音频取证若干关键技术研究进展
Research Progress on Key Technologies of Audio Forensics
摘要
Abstract
The latest research progress in audio forensics is introduced with the emphasis on audio authen‐ticity .First ,the history of audio forensics research is reviewed .The classification of audio forensics is discussed .Then ,the framework of audio forensics is designed .Several key technologies of audio foren‐sics are summarized including audio active forensics technology ,audio tamper technology based on electri‐cal network frequency (ENF) ,audio tamper detection technology with different sampling rates and audio tamper detection technology with the same sampling rates under the passive power grid frequency compo‐nents ,the characteristic parameters of recording equipment ,pattern recognition ,situation of database construction ,recording environment identification and so on .Finally ,the prospective of audio forensics technology is presented .关键词
