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.
