Detecting and embedding Digimarc watermarks

A Digimarc watermark embeds copyright details, contact information, and image attributes in an image. A watermark makes subtle changes to the brightness of pixels in an image. These changes cannot be readily seen; however following image processing, you might notice changes in the brightness of some pixels. Digimarc watermarks aren’t affected by normal editing, printing, and scanning.

The detecting and embedding of Digimarc watermarks is not supported by the 64-bit version of CorelDRAW Graphics Suite.

Detecting watermarks

When you open an image in Corel PHOTO-PAINT, you can check for a watermark. If a watermark is present, a copyright symbol displays on the title bar. You can find information about the watermarked image by reading the embedded message and by linking to the contact profile in the Digimarc database.

Embedding watermarks

In Corel PHOTO-PAINT, you can also embed Digimarc watermarks in images. First, you must obtain a unique Creator ID by subscribing to Digimarc’s online service. The Creator ID includes contact details, such as name, phone number, address, e-mail and web addresses.

Once you have a Creator ID, you can embed a watermark in an image. You can specify the copyright year, image attributes, and the durability of a watermark. You can also specify the target output method for an image, such as print or web.

Digimarc watermarks do not prevent unauthorized image use or copyright infringement. But the watermarks do communicate copyright claims. They also provide contact information for those who want to use or license an image.
