Self-Destructing or Time-Limited Files
From time to time in business, I have to send someone files, typically pdf and jpg. It is important that those files be limited in function to make them difficult to pass along to others. The receiving party typically needs them for 2 hours or less.
Is there a way to render the files useless after a certain amount of time?
For example, can they be automatically overwritten (thereby effectively deleting them) or rendered impossible to open after a given period of time?
Are there other methods to accomplish the goal I haven't thought of?
I've poked around the internet but I haven't found what I need.
Thank you for the assistance.
