Ok, this a new one for me. While browsing around for more info for this blog, I ran into Numly Numbers. www.numly.com Numly calls itself a "copyright and license management corporation" that provides electronic serial numbers for digital content. What does that mean?
Basically, if you add original content to the Web, you can use a Numly number to prove ownership of the material. Bloggers can even get a service where a Numly number is generated each time a post is made. This is a way to help prove ownership of content should it be plagiarized. Is there a foolproof way to ensure this does not happen? No, but using Numly numbers could be a step in the right direction.
According to www.numly.com a user can get 100 numbers in a month for $4.95.
