Abstract

This disclosure enables consumers to download a large selection of music, video, or other protected digital content into their personal devices and only pay for the selections they access at a later time. The capability described is particularly useful in environments where reliable network access cannot be guaranteed as it does not require real time authorization for access to protected content.

Locally Controlled Digital Content Access Authorization Based on Pre determined Platform Trust Attributes

Trusted Platform capabilities allow a system to verifiably report platform security characteristics such that a connected entity can 'trust' the accuracy and reliability of these functions. Typical Trusted Platform function includes digital encryption/decryption, user authorization, device authorization, and trusted time.

The following flow diagram describes how a Trusted Platform can be used to implement a robust 'push now, authorize later' content control system.

Max queue refers to the max number of payment authorizations that can be queued without network connectivity and authorization. In other words it sets a max threshold of how many 'titles' you can access while in disconnect (trust me, I'll connect later) mode. It clears after network connectivity is established and all the queued payment authorizations are processed.
