I was curious if anyone on here has any experience with writing code to read digital watermarks out of an image. I'm not talking about what we normally think of as a watermark (like a copyright on a photo), but the invisible watermarks that can be used to verify ownership of an image. In particular, I need to be able to read the digital watermark with the iPhone camera and then redirect the user to a website. For an example of what I'm referring to, check out https://digimarc.com/.
Thanks! Bob
