The following update was prepared by Mike Taylor, C.P.M. for use by volunteers who are taking care of affiliate web sites. The information is intended to be practical, not technical.
Do you post images on the internet? Do you post them for anyone else to freely copy, use and distribute? If not, how do you protect the images and/or prove they are really yours? Adding a digital copyright or watermark to images before you post them is one way to help identify them. In some cases the watermark can act as a digital ID tag so you can search the web to see who else might be using the image.
Probably not a big issue if all you are posting is grainy snaps of the latest dinner program. However, I know of at least one instance where one of my images was added to a photo index. I also wouldn't be surprised if someone had downloaded a picture of me to make one of those fake celebrity-head-on-a-different-body pictures. (It's probably hard to tell if it's really me or Arnold.)
The solution is to add a digital marker to the images. Call it a digital watermark, copyright or even an encryption scheme. There is a lot of information about the process and some free tools to help you do protect your images. Soooooo if you are going to post an image that someone might want to 'borrow' here are some resources:
