摘要： 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.

摘要： Digital content is rendered on a device by transferring the content to the device and obtaining a digital license corresponding to the content. A sub-license corresponding to and based on the obtained license is composed and transferred to the device, and the content is rendered on the device only in accordance with the terms of the sub-license. The content is encrypted and decryptable according to a content key, and the sub-license includes the content key encrypted and decryptable according to a secret. The sub-license also includes indexing information identifying the secret to the device. The indexing information in the sub-license is obtained to identify the secret, and the secret is acquired based at least in part on the indexing information. The secret is then applied to the encrypted content key to decrypt and obtain the content key, and the obtained content key is applied to the encrypted content to decrypt and obtain the content. To compose the sub-license and also to render the content, the secret is derived by obtaining a device identifier, acquiring a super-secret, and applying the obtained device identifier and super-secret to a function to derive the secret.

摘要： Techniques enable creation of a preview license for digital content. In some instances, the preview license indicates that it allows a content-consuming device to consume less than all of the content. This preview license may create a list specifying multiple portions of the digital content that the content-consuming device may consume. These techniques may also present to a device user an offer to purchase rights to consume all of the digital content after consumption of the preview-licensed portion(s). In other instances, a content server may embed the preview license into a content package that contains the digital content, allowing the server to distribute the package to multiple devices. In still other instances, the preview license may be bound to a domain rather than to individual devices. This allows member devices to share the digital content and the preview license, such that each member device may enjoy the preview experience.
