Centre sets digital watermarking standards
The Centre for Democracy & Technology is releasing a set of principles on how to use digital watermarking technology.
Digital watermarking technology embeds information, in machine-readable form, within the content of a digital media file, such as an image, audio or video file. In some applications, the watermark signal identifyies information about the media file itself, such as its title or author. In other applications, watermarks can provide individualised user or transaction information.
CDT's principles address privacy questions that may arise when watermarks provide information about individual consumers or users. In developing its privacy principles for digital watermarking, the CDT consulted with industry representatives and interested privacy advocates. The principles may be viewed at www.cdt.org.
