Abstract
A data access policy is configured and stored on a computing device, including a list of secure gateway IP addresses and optionally secure geographic regions. A time parameter defines how long a digital file will remain not in use before deletion and a degree parameter defines how fast the file will be deleted. Once a digital file is downloaded to the computing device the device is checked periodically to determine whether or not it is in a secure location. If not in a secure location then a data deletion process is initiated which begins by checking whether or not the digital file is currently being used on the computing device. If the file is being used, then no deletion is performed. If the file is not in use (or has not been used after a certain amount of time) then the file is deleted. The file may be deleted gradually.
