The blockchain boy posts some amazing things.  He has come up with this system to protect your average word or excel document with blockchain technology.  Almost the entire corporate world will be using blockchain if his predictions are accurate and if he builds the system.

Here is the top of his blog post:
Intellectual property theft is widespread and costs companies billions of dollars in damages. Unauthorized music, movie and document sharing are very common and have become much easier because of all the new cloud services such as drop box, google docs, bit torrent and cloud based storage. We hear a lot about services such as artbit and artsmesh protecting the music industry using blockchain.

I will not post more too much info here posts should be short ...also you absolutely must read the whole article
right now to understand how big this will be.
