US Patent 7496540 System and method for securing digital content

A system is disclosed for a digital rights management system which enforces license rights by incorporating a decryption key in a license rights package that further includes an account number associated with a primary consumer. The digital rights management system also includes a mechanism for renewing/updating the license by charging the account number associated with a primary consumer. This way, the consumer may transfer the license rights package along with the digital content to any personal devices he likes but he is discouraged from freely disseminating the license package as uses by other consumers will be debited against his package or, if renewed/extended, charged against his account.
