Custom Firefox Build

Post by Todd_Z »

I am developing software which contains data that has a value of around $2,000 per row, and because of this, I need to ensure the client that users will be unable to simply take the information and run.

The good news is that often the users of the software will be idiots and/or technologically.... impaired.

My semi-solution is the following:

I create a custom firefox build with disabled printing for a certain domain -> whatever domain the software is on.
I alter the user-agent to be a fake version of firefox - 1.5.0.2 so that when someone tries to login to the software, I will make sure they are using a custom built version of fx.

Problems with this idea:

People can always take screenshots, but quite frankly, there isn't much I can do about that.
Users could theoretically use another firefox version with a user-agent spoofer to replicate the headers. -> 99.9% of users won't know how to do this.


Anyone have any ideas on this system?
Anyone have experience with altering firefox like this?

place the data into a required site extension (ActiveX for IE and whatever for Firefox, or something) that uses overlays. Overlays cannot be screenshot in any standard way (the actual video output of the card has to be intercepted and stored).. the only holes are if people take an actual photo of the screen, not too much you can do about that one I'm afraid. There are alternates where you can use restricted PDF files (although it can be hacked) and Flashpaper files.

It may be better to concentrate on creating a very solid license for people who are viewing these pages where you have to get real signed contracts or something from them if it's that important.
