Auto Time Deletion

I am wondering if there is a way to put in a code so if after a certain time
frame, when someone goes to open a db it will self destructs or delete it
self so it can't be retrieved or useable in any way.
Example: I send you a db to look at or work on and I never here from you
again or am not satisfied with the results that I get.When you open the db
lets say 2 weeks after I send it to you, it will automatically destroy or
delete it self so you can't use or copy it.

Thanks Blair
