  • Patent number: 7779249
    Abstract: A host securely transmits content to a peripheral thereof. The peripheral has a symmetric key (PK) and a copy of (PK) encrypted according to a public key (PU) of an entity ((PU(PK))). In the method, the host receives (PU(PK)) from the peripheral, and sends (PU(PK)) to the entity. The entity has a private key (PR) corresponding to (PU), applies (PR) to (PU(PK)) to obtain (PK), and sends (PK) back to the host. The host receives (PK) from the entity, encrypts at least a portion of the content according to (PK), and transmits the encrypted content to the peripheral. The peripheral may then decrypt the encrypted content based on (PK). A bind key (BK) encrypted by (PK) ((PK(BK))) may accompany (PU(PK)), where the content is to be encrypted according to (BK). Thus, (PK) is not revealed to the host.

  • Patent number: 7644446
    Abstract: 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.

  • Patent number: 7568096
    Abstract: A request to render encrypted content is received and a chain of licenses corresponding to the content is located. The chain includes a leaf license linked to the content at one end of the chain, a root license at the other end of the chain, and any intermediate licenses therebetween. The leaf license and any intermediate licenses in the chain are each bound to the adjoining license in the chain toward the root license, and the root license is bound to an owner of a private key (PR-U). For each license in the chain, the license is verified and it is confirmed that the license allows the content to be rendered. A decryption key is obtained from the leaf license based on application of (PR-U) to the root license, the obtained key is applied to decrypt the encrypted content, and the decrypted content is rendered.

  • Patent number: 7395438
    Abstract: A device renders content on a medium by obtaining a table from the medium, obtaining a device key (DK) of the device and an index value of such (DK), indexing into an entry of the table based on the obtained index value, selecting an encrypted secret from the indexed-into entry, applying the obtained device key (DK) to the selected encrypted secret to expose the secret, and applying the exposed secret to render the content.

  • Patent number: 7337390
    Abstract: A method of embedding voice data in a computing system includes detecting a record event and detecting if a software application currently running on the computing system is voice-aware. The method also includes embedding the voice data within associated data in the software application, if the software application is voice-aware. If the software application is not voice-aware, the method also includes triggering a voice note application to record and store the voice data. A method in a computing system for modifying a user interface displayed on a display device includes receiving an indication from the computing device to modify the user interface. The method further includes displaying an identification block, a record toolbar, a note pad, and a note tab.

  • Patent number: 7281273
    Abstract: Digital content is encrypted according to a content key (CK) to form (CK(content)) and such (CK(content)), a license generator, a start-up file, and license-generating information are placed on a digital storage medium. The license generator is for generating a digital license corresponding to the placed content, where the generated license has the content key (CK) therein. The start-up file is read and executed when the medium is mounted to a computing device, and the executed start-up file executes the license generator The license generating information includes the content key (CK) and any terms, conditions, rules, and/or requirements to be built into the license.
