摘要：Techniques and systems for managing digital rights can be implemented toprotect against unauthorized copying of digital content and to help ensure payment to

content owners and distributors. Digital wrappers can be applied (310, 1020) to data filesto prevent access (135, 340, 440) without a valid authorization. Information relating toauthorizations to access data files and/or keys for accessing the data files may be storedand retrieved using data stored in a non-volatile storage area (220) of a user device (205).Software on the user device can be used to recognize files (110, 415) and to apply digitalwrappers (310, 455, 1020) to recognized files. In addition, the software can be used toremove digital wrappers (360, 685, 770) from files in accordance with authorizations toaccess the files. Payments or other credits can be allocated (920, 940) among distributorsof a data file using information associated with the digital wrappers.
