1. A method of restricting access to digital content data, comprising:
- storing the digital content data on a user device;
classifying the digital content data to determine whether the digital content data is controlled digital content data or non-controlled digital content data;
if the digital content data is controlled digital content data;
storing a trusted voucher on the user device, the trusted voucher being associated with the controlled digital content data and comprising at least one permitted function; and
restricting access to the controlled digital content data by the user device to said at least one permitted function; and
if the digital content data is non-controlled digital content data;
associating a local voucher stored on the user device with the non-controlled digital content data, the local voucher comprising at least one intended function;
restricting access to the non-controlled digital content data by the user device to said at least one intended function;
restricting access to the non-controlled digital content data based on a physical characteristic of the user device; and
wherein the physical characteristic includes one or more of a maximum number of non-controlled digital content data stored on the user device, and a duration of time since the storing of the digital content data on the user device.

Abstract
A method, computer system, and computer program product for restricting access to digital content data. The disclosed invention stores the digital content data on a user device, and classifies the digital content data as either controlled data or non-controlled data. If the digital content data is controlled data, the disclosed invention stores a trusted voucher on the user device, the trusted voucher being associated with the controlled data and comprising at least one permitted function, and restricts access to the controlled data by the user device to said at least one permitted function. If the digital content data is non-controlled data, the disclosed invention associates a local voucher stored on the user device with the non-controlled data, the local voucher comprising at least one intended function, and restricts access to the non-controlled data by the user device to said at least one intended function.

4. A computer system for restricting access to digital content data, comprising:
-
a memory device; and
a processor disposed in communication with the memory device, the processor configured to;
store the digital content data on a user device;
classify the digital content data to determine whether the digital content data is controlled digital content data or non-controlled digital content data;

7. A computer program product for restricting access to digital content data, comprising:
-
a computer readable medium;
program code in the computer readable medium for storing the digital content data on a user device;
program code in the computer readable medium for classifying the digital content data to determine whether the digital content data is controlled digital content data or non-controlled digital content data;
program code in the computer readable medium for storing a trusted voucher on the user device, the trusted voucher being associated with the controlled digital content data and comprising at least one permitted function;
program code in the computer readable medium for restricting access to the controlled digital content data by the user device to said at least one permitted function;
