6. The system of claim 5 , wherein said particular movement detecting module comprises: a tilt detecting module configured to detect that the computing device has moved in the particular manner when the tilt detecting module at least detects that the computing device is no longer in a particular tilt orientation that the computing device was detected as having when the computing device was in possession of the first user prior to said transfer.
7. The system of claim 6 , wherein said tilt detecting module comprises: a tilt detecting module configured to detect that the computing device is no longer in a particular tilt orientation that the computing device was detected as having when the computing device was in the possession of the first user by at least detecting that the computing device has been reoriented from the particular tilt orientation to another tilt orientation having an angular tilt that is at least a predefined percentage different from an angular tilt associated with the particular tilt orientation that the computing device was detected as having when the computing device was in the possession of the first user.
