Discriminating data protection system
First Claim
1. A non-transitory computer readable medium having stored thereon an agent program that instructs an electronic device to at least:
- determine, in response to a trigger that represents a need to take a data protection measure, a first point in time prior to the trigger, said first point in time being of a last known authorized use of the electronic device, the trigger related to a theft or loss of the electronic device;
identify first data on the electronic device that was created prior to said first point in time;
identify second data on the electronic device that was created between said first point in time and the trigger; and
execute a discriminating data protection policy that treats the first data differently from the second data.

Abstract
A data protection system selectively deletes data from an electronic device when the device is reported as lost or stolen, or when another data protection triggering event occurs. Different data files may, for example, be treated differently depending on when such files were created. For example, data files that were created while the computing device was known to be in the owner'"'"'s possession may be deleted, while data files created after the electronic device left the owner'"'"'s possession may be left intact (since they may have been created by an innocent user). Data files created between these two points in time may be quarantined so that they later be restored, if appropriate.

11. A system for protecting data, the system comprising:
an electronic device having a processor and a memory, the electronic device configured to; determine, in response to a trigger that represents a need to take a data protection measure, a first point in time prior to the trigger, said first point in time being of a last known authorized use of the electronic device, the trigger related to a theft or loss of the electronic device; identify first data on the electronic device that was created prior to said first point in time; identify second data on the electronic device that was created between said first point in time and the trigger; and execute a discriminating data protection policy that treats the first data differently from the second data. - View Dependent Claims (12, 13, 14, 15)

16. A method for protecting data stored on an electronic device until ownership of the data can be determined, the method comprising:
by the electronic device under control of an agent program; determining, in response to a trigger that represents a need to take a data protection measure, a first point in time prior to the trigger, said first point in time being of a last known authorized use of the electronic device, the trigger related to a theft or loss of the electronic device; identifying first data on the electronic device that was created prior to said first point in time; identifying second data on the electronic device that was created between said first point in time and said trigger, said first and second data therefore potentially belonging to different owners; and executing a discriminating data protection policy that treats the first data differently from the second data. - View Dependent Claims (17, 18, 19)
