Abstract
Unlocking digital content embodied in digital readable form on a digital media carrier includes generating a test based on text that is printed in a physical copy of the digital content, prompting a user to input text that appears on a specific page of the physical copy, evaluating whether the user entered the correct word; and if the word was correct, unlocking the digital content.
