Hardware architecture for security improved Fallahpour audio watermarking scheme

Abstract

One of the audio watermarking schemes with highest payload published to date is Fallahpour scheme, achieving about 3 kbps [1]. A keybased security improvement to this algorithm is proposed in [2] while significatively maintaining the payload. In this letter, a high throughput and compact hardware architecture for the Security Improved Fallahpour Audio Watermarking Scheme is proposed, demonstrating the suitability of this algorithm for real-time applications.
