    摘要: Metered data is accumulated and is indexed within a metering database of a client according to a metering ID (MID) and a content-associated ID (KID). The client selects a particular MID and metered data in the metering database having the selected MID, and constructs a challenge based on the selected metered data and sends same to a metering service. The metering service obtains the metered data from the challenge, stores same, and constructs a response. The client receives the response including a list of KIDs of the selected metered data in the challenge, and processes the list of KIDs by, for each KID in the list, deleting the metered data from the metering database having the selected MID and the KID.

    摘要: A digital license includes an identification of a removal service that can authorize removing such license. A client selects the license to be removed and the service, constructs a challenge including therein a challenge license identification block (LIB) identifying the license to be removed, and sends the challenge to the service. The service receives the challenge, stores at least a portion of the challenge in a database, constructs a response corresponding to the challenge and including therein a response LIB identifying the license to be removed and an identification of the service, and sends the response to the client. The client receives the response, employs the response LIB from the response to identify the license to be removed, and removes the identified license upon confirming that the identification of the service in the identified license matches the identification of the service in the response.

    摘要: A source generates a medium key (KM) and a media secret table including a plurality of entries, each entry including (KM) encrypted by a public key (PU-PD) of a plurality of devices, obtains the medium ID of a medium therefrom, generates a content key (KD) for a piece of content, encrypts the content with (KD) to result in (KD(content)), encrypts (KD) with (KM) to result in (KM(KD)), generates a package for the content including (KD(content)), (KM(KD)), the medium ID, and a signature based on at least the medium ID and verifiable with (KM), and copies the generated package and the media secret table to the medium. Thus, a device with the medium and a private key (PR-PD) corresponding to an entry of the media secret table can access and render the content.
