Data Hiding Scheme for Amplitude Modulation Radio Broadcasting Systems
2014
Journal of Information Hiding and Multimedia Signal Processing
This paper proposes a data hiding scheme for amplitude-modulation (AM) radio broadcasting systems. The method of digital audio watermarking based on cochlear delay (CD) that we previously proposed is employed in this scheme to construct a datahiding scheme in the AM domain. We investigate the feasibility of applying the method of CD-based inaudible watermarking to send inaudible additional messages in AM signals. The proposed scheme modulates a carrier signal with both original and watermarked
