"CDT Issues Privacy Principles for Digital Watermarking - CDT today released a paper offering a set of principles for addressing potential privacy considerations when deploying digital watermarking technology. This technology embeds information within the content of digital media files in a form that is machine readable but often imperceptible to humans. Digital watermarking has a variety of applications and is increasingly being considered as a tool for deterring copyright infringement. CDT's paper is intended to provide guidance for companies that plan to use the technology to communicate information that is specific to individual consumers. May 29, 2008"
