Abstract
A technique that inserts data densely into short frames in a digital audio signal by frequency domain dithering is described. With the proposed method, large embedding capacity can be realized, and the presence of the hidden data is imperceptible. Synchronization in detection is achieved by using a two-step search process that accurately locates a PN sequence-based pilot signal attached to the data during embedding. Except for a few system parameters, no information about the host signal or the embedded data is needed at the receiver. Experimental results show that the method is robust against attacks including AWGN interference and MP3 coding.
