Protecting Images with Watermarks

Digital watermarks are designed to protect your intellectual property. When you embed a digital watermark, it actually inserts the watermark information as visible noise into the image. This means that someone can copy your image, scan it, and the watermark is still part of the image. To embed a digital watermark, you must first register with Digimarc Corporation; which maintains a database of artists, designers, and photographers and their contact information. You can then embed the Digimarc ID in your images, along with information such as the copyright year or a restricted-use identifier.

Protect Images with Watermarks

Open the image you want to watermark.

IMPORTANT

The Embed Watermark filter won't work on an image that has been previously watermarked.

If you're working with a layered image, you should flatten the image before watermarking it; otherwise, the watermark will affect the active layer only.

Click the

Filter menu, point to

Digimarc , and then click

Embed Watermark .

If you're using the watermark for the first time, click

Personalize . Get a Digimarc ID by clicking Info to launch your Web browser and visit the Digimarc Web site at www.digimarc.com.

Enter a Digimarc ID and any other necessary information, and then click OK.

The Personalize button becomes a Change button, allowing you to enter a new Digimarc ID.

Click the

Image Information list arrow, select an option, and then enter a copyright year, Transaction ID, or Image ID for the image.

Select any of the following Image Attributes check boxes:

• Restricted. Select the check box to limit the use of the image.

• Do Not Copy. Select the check box to specify the image should not be copied.

• Adult Content. Select the check box to label the image contents as suitable for adults only.

Click the

Target Output list arrow, and then specify whether the image is intended for Monitor, Web, or Print.

Drag the slider, or enter a value (1 to 4). The higher the number, the more aggressive the watermark.

To automatically assess the watermark's durability after it's embedded, select the

Verify check box.

Click

OK .
