An audio watermarking scheme based on extended bipolar echo kernel and robust to temporal offsets
This paper presents a novel audio watermarking scheme based on echo hiding technique. This method is different from conventional echo hiding methods which embed only one bit in each audio section. In this method by using different echo delays we can embed more than one bit in each audio sections. For enhancing robustness of proposed algorithm against various types of attacks, we exploit dual echo kernels. Experimental results show that proposed method has good performance in robustness and inaudibility point of view.
