implement a DRM mechanism. One way is to build an authentication server, log against a license, and rotate licenses as needed if you find curious activity. This is not a new problem and has been done previously. You may need to get creative with the code. I'm assuming that your model is quite visible for someone to reverse engineer by looking at VB project in Excel. You need to find a way to hide it as well.
- graham1776 13y agoNot going to lie, sounds like brain damage, especially for super non-technical real estate folks (I am one). What do you think about a Citrix/Virtual Machine where the client could use the excel sheet over internet, play with it, without any connection to the outside world (ie email, dropbox, internet). Owner of the document would have full ability to download and edit, but client would only be able to edit and save within the virtual machine... Overcomplicating much?
- pettycash 13y agosure - I understand. I can't comment on Citrix/VM setup. Once they have access to the document, they will be able to screenshot it. etc. Sounds like you need to keep it simple. I did a google search for "excel document drm solutions". You'll need to investigate all solutions for yourself, but looks like there are plenty off the shelf solutions.
