Hardware architecture for security improved Fallahpour audio watermarking scheme

Hardware architecture for security improved Fallahpour audio watermarking scheme

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, demonstrat...

Improving the security of Fallahpour's audio watermarking scheme

The audio watermarking scheme recently proposed by Fallahpour in [1] is one of the schemes with highest payload published to date. In this letter a key-based security improvement is proposed for that scheme. It is achieved by adding a Pseudo-Random Number Sequence (PRNS) in the frequency domain to the data samples, before applying the insertion algorithm. Experimental results show that the prop...

A Watermarking Scheme for MP3 Audio Files

In this work, we present for the first time in our perception an efficient digital watermarking scheme for mpeg audio layer 3 files that operates directly in the compressed data domain, while manipulating the time and subband/channel domain. In addition, it does not need the original signal to detect the watermark. Our scheme was implemented taking special care for the efficient usage of the tw...

Audio Watermarking Scheme in MDCT Domain

In our proposed watermark embedding system, the original audio is segmented into overlapping frames. The psychoacoustic auditory model has been utilized to calculate the global threshold in modified discrete cosine transform domain. The perceptual insignificant locations have been used to insert the appropriately scaled watermark in the transform domain. Blind detection of watermark has been pe...
