Data leakage prevention in cloud-endpoint model

A method of deleting a digital file, said method comprising:

• defining a data access policy including an identification of secure IP addresses and storing said data access policy within a computing device;
• defining a degree parameter as part of said data access policy that indicates a time interval;
• downloading a digital file subject to said data access policy from a computer server to said computing device;
• determining whether said computing device is in a secure location by comparing an IP address of said computing device with said secure IP addresses;
• initiating a deletion process when it determined that said computing device is not in said secure location;
• as part of said deletion process, determining whether said digital file is currently being used on said computing device;
• and
• deleting said digital file from said computing device gradually over said time interval when it is determined that said digital file is not currently being used on said computing device, wherein said digital file is deleted gradually by successively transforming an image of said digital file such that said image becomes successively more blurry.

A method of deleting a digital file, said method comprising:

• defining a data access policy including an identification of a secure geographic region and storing said data access policy within a computing device;
• defining a degree parameter as part of said data access policy that indicates a time interval;
• downloading a digital file subject to said data access policy from a computer server to said computing device;
• determining whether said computing device is in a secure location by comparing GPS co-ordinates of said computing device with said secure geographic region;
• initiating a deletion process when it determined that said computing device is not in said secure location;
• as part of said deletion process, determining whether said digital file is currently being used on said computing device;
• and
• deleting said digital file from said computing device gradually over said time interval when it is determined that said digital file is not currently being used on said computing device, wherein said digital file is deleted gradually by successively transforming an image of said digital file such that said image becomes successively more blurry.
