It's been a while since I've blogged. I'm working on an InfoPath project and that has consumed my working hours and several of my free time hours as well.
One pretty cool thing we will be using in the project is the Digital Signature capability in InfoPath SP1.
Our form will include several views that are used to populate one large schema with data. The form will not be completely filled out at one sitting. As users fill out the various views, we will allow them to digitally sign the data thus certifying its validity. InfoPath SP1 allows us to sign just certain pieces of the data as we move through the process. Once the data is signed, it will become read-only to prevent tampering, either accidental or intentional.
The above MSDN article give a good background on signing data in InfoPath.
