One of the problems when sending MS Word documents around is that sometimes the meta data that is a part of them can leak internal details. Things like actual meta data, but also comments and revision history. Typically when sending to an external collaborator you would have a system that strips all this information. But what if you could have both?
Introducing Meta Secure. A system that encrypts the metadata within the file itself. You log into meta-secure and it decrypts any meta information attached to the file (so long as you have access to decrypt it).
My favorite one!
Not that hard, easy to market and get grants to develop it
But who is the market? I was originally thinking lawyers, but maybe they don’t care or have other solutions. If you can sell it, I can build it 😛
