InfoPath Dev

Problem
There is no intrinsic way to lock an InfoPath form to prevent someone from opening it in design mode or using a zip utility. Do you have any suggestions as to how this might be done?

Solutions
Yes, the protect option in InfoPath is a bit flimsy and doesn#%92t prevent someone from cracking the form. This leads to a host of privacy issues.

Some random ideas:

• Use online secondary data resources for sensitive data.
  we typically do not use secondary data resources (2DS) in the solution when there are privacy concerns.


• If you must have offline, encrypt the data into a binary file and have your .NET assembly in InfoPath decrypt it based on a key
  the .NET assembly is compiled so slightly harder to crack
  

Hope this helps!
