Audio signals and applications are numerous and ubiquitous. Most of these applications especially those on the Internet require authentication and proof(s) of ownership. There are several efficient methods in the literature address these crucial and critical concerns. In this paper, the authors present a new non-blind audio watermarking scheme for forensic audio authentication and proof of ownership. The proposed scheme is based on empirical mode decomposition and Hilbert Haung Transformation (HHT). In this method, the audio signal is decomposed into frames of 1024 sample each. These frames are further decomposed into its several mono-component signals called Intrinsic Mode Functions (IMF). These Intrinsic Mode Functions will serve as the addressee for the watermark. In this research, the chosen watermark is a pseudo random number generated by Matlab-7, which is added to the highest and lowest IMFs of each frame of the decomposed signal. This is done to accommodate for time scale modification attacks as well as MP3 compression respectively. Experimental results show that the watermarked audio signals maintained high fidelity of more than 20 dBs which meets the International Federation of Phonographic Industry requirements. The results also show that the proposed scheme is robust against signal processing attacks such as MP3, time scale modification, and resizing attacks.<\/p>","DOI":"10.4018\/ijdcf.2013100104","type":"journal-article","created":{"date-parts":[[2014,3,21]],"date-time":"2014-03-21T13:53:20Z","timestamp":1395410000000},"page":"55-67","source":"Crossref","is-referenced-by-count":0,"title":["Audio Watermarking Scheme Using IMFs and HHT for Forensic Applications"],"prefix":"10.4018","volume":"5","author":[{"given":"Saif","family":"alZahir","sequence":"first","affiliation":[{"name":"Department of Computer Science, University of Northern British Columbia, Prince George, Canada"}]},{"given":"Md Wahedul","family":"Islam","sequence":"additional","affiliation":[{"name":"Department of Computer Science, University of Northern British Columbia, Prince George, Canada"}]}],"member":"2432","reference":[{"issue":"1","key":"ijdcf.2013100104-0","first-page":"6","article-title":"Digital audio watermarking based on the discrete wavelets transform and singular value decomposition.","volume":"39","author":"A.Al-Haj","year":"2010","journal-title":"European Journal of Scientific Research"},{"key":"ijdcf.2013100104-1","doi-asserted-by":"crossref","unstructured":"alZahir, S., & Islam, W.
