Can I “lock” copyright metadata in an image?

Question

I'm going to be distributing some of my images as TIFF files and want to put my copyright and contact information into the metadata for the images in a way that prevents it being stripped or altered by third parties. At the moment I'm using Photoshop CS5 and inserting the information using Bridge. Is there a method for locking the metadata that anyone can recommend?

Answer

Anyone with an editor can open a TIFF and save it again without the metadata. I don't think there is any way to lock the metadata from being stripped out.

You could look at digital watermarking, such as Digimarc
