Here is the problem with digimarc, at least this was the problem when we used it.

When you digimarc the photos, you have to select a setting between 1 and 5.

1, 2, and sometimes 3, the spider never found the images.

4 and 5 always caught the images. However, using 4 or 5 degraded the image noticeably.

Although, that was 10 years ago. With the 12, 13, 16 megapixel cameras being used now, it might not matter.
