ABSTRACT:
A method executed on a server for unlocking digital content includes receiving a message corresponding to a request to access digital content embodied in digital readable form, associated with an electronic representation of a publication, sending a test that is based on the user having physical possession of the publication; receiving and evaluating an answer to the test to determine whether the correct answer was received; and if the answer was correct, providing access to the digital content associated with the electronic representation of the publication.
