    摘要： A method and system for associating metadata with an encrypted content item, the method including receiving metadata for association with a content item, receiving an entitlement control packet (ECP) associated with the content item, applying a cryptographic hash function to the ECP, thereby generating an ECP hash value, combining the ECP hash value with the metadata, thereby creating a data control object, performing a cryptographic operation on the data control object, thereby generating cryptographic integrity data, and joining the cryptographic integrity data to the data control object after the cryptographic operation, wherein usage of the content by the recipient is dependent on both a validation of the ECP hash value and a validation of the cryptographic integrity data. Related apparatus and methods are also described.
