The First Affordable Watermarking Solution
watermark: 1. Faintly visible impression or mark on paper (e.g. currency). 2. Imperceptible and hidden information embedded within rich media (e.g. audio or music, video, images). û digital watermark.

We all know what watermarking on a dollar bill does. It provides security by allowing the legal printer or owner of the billùthe governmentùto identify the bill as legal. Watermarks are also used to communicate information from manufacturers to consumers. For example, paper manufacturers watermark their paper to brand their product. Each "brand" represents a paper quality that helps the consumer make informed purchasing and use decisions.

Audio watermarks work in much the same way. Information is embedded directly into the audio signal by the content owner to provide security, and to communicate information to listeners, whether the audio is in digital or analogue formats. The watermark remains with the audio whether the file is then pressed onto a CD, burned to a CD R, broadcast, webcast, emailed to another party or posted to an Internet website.

CognicityÆs AudioKey is a digital watermarking tool that allows you to easily watermark your music. Here are some benefits you get by using CognicityÆs AudioKey Personal version:

Security -- By embedding copyright information or unique digital identifiers such as ISRC, ISWC, ISCI, part number, or Project ID, you can distribute your music with the confidence that you have put people on notice that you own the music being distributed.

Communication -- Provide your listener with your contact or linking information like e-mail, phone number, URL or hyperlinks.

Quality retentionùOur watermark is inaudible-- the quality of your music remains exactly the same after you watermark it. We call this "transparency", and our watermark has satisfied the most demanding "golden ears" tests.

RobustnessùThe watermark is impractical to delete. Anyone who attempts to delete the watermark in any audio format (digital or analog) deteriorates the music that embeds the watermark, making it impractical for anyone to want to tamper with the music.
