Celoxica Says Research Project Speeds Digital Watermarking

Celoxica has teamed with the Japan Advanced Institute of Science and Technology (JAIST) to develop a high-speed digital watermarking detection system with real-time operation across the Internet, according to Celoxica, a developer of electronic system level (ESL) design tools.

SAN FRANCISCO — Celoxica has teamed with the Japan Advanced Institute of Science and Technology (JAIST) to develop a high-speed digital watermarking detection system with real-time operation across the Internet, according to Celoxica, a developer of electronic system level (ESL) design tools.

Celoxica (Abingdon, England) said the joint research project, which used ESL design and C-based synthesis to accelerate watermarking algorithms in a hardware co-processor, yielded a low-power solution that runs detection scanning 148 times faster than pure software configurations. The algorithm design was implemented using Celoxica's DK Design Suite of ESL tools and RC Series hardware platforms, the company said.

Digital watermarking, which embeds hidden data into digital content or media, is a technology intended to prevent illegal copying and distribution of multimedia content. Digital watermarks contain copyright information identifying the origins, ownership and authenticity of content.

According to Celoxica, the research project at JAIST developed an accelerated watermarking solution for audio content. The project increased detection efficiency and implemented multiple watermarks in parallel using hardware co-processing, the company said.

"Digital watermark detection by software alone is too slow and power hungry, and it cannot catch illegal audio files that are exchanged over the Internet," said Yasushi Inoguchi, associate professor at the center for information science at JAIST, in a statement. "Using C-based design and synthesis technology we were able to easily capture the complex watermarking algorithms and accelerate the watermark detection scheme in a co-processor, exploiting the power and performance benefits of programmable hardware."
