摘要： A network system includes a content provider connected to local service providers via an interactive distribution network, such as the Internet. The local service providers facilitate delivery of the content from the content provider to multiple subscribers. The local service providers schedule delivery of frequently requested content from the content provider prior to a peak time when the subscribers are likely to request the content. The content is downloaded from the content provider during the off-peak hours and cached at the local service providers for serving to the subscribers during the ensuing peak time. In this manner, the frequently requested content is already present at the local service providers and ready to be served to the subscribers before they actually request it. When the content is finally requested, the data is streamed continuously in real-time for just-in-time rendering at the subscribers computer. Another aspect of this invention involves supplementing content delivery over the Internet with delivery of content over a secondary network, such as a broadcast satellite network. The supplemental broadcast link offers additional bandwidth at a fraction of the cost that would be incurred if the local service provider installed additional Internet connections, such as T1 or T3 connections.

摘要： Computer-executable instructions that are directed to the performance of consequential actions and automatically elevate to execute at a higher privilege level to do so can perform such consequential actions only after user notification. Doing so can enable monitoring processes to avoid presenting duplicative user notification upon detection of such auto-elevation. In addition, prior to presenting user notification, input from the execution environment can be ignored and access to DLLs for performing consequential actions can be avoided. A static analyzer can identify non-conforming computer-executable instructions. A wrapper can be utilized to provide compliance by otherwise unknown or non-conforming computer-executable instructions.

摘要： A scope hierarchy corresponding to a resource to which a type of access is requested is identified, the scope hierarchy including multiple scope levels each of which has an associated access control list. An access control list associated with a lower scope level can further restrict access permitted to the resource by an access control list associated with a higher scope level. Based at least in part on one or more of the access control lists associated with the multiple scope levels, a determination is made as to whether the requested type of access to the resource is permitted.

摘要： A distributed system in which time-dependent credentials are supplied by controllers that operate according to different local times. Errors that might arise from the controllers generating inconsistent credentials because of time skew are avoided by identifying credentials generated during transition intervals in which different ones of the controllers may generate different credentials at the same absolute time. During a transition interval, controllers and other devices may use credentials differentially based on the nature of the authentication function. Each controller may periodically renew its credentials based on self-scheduled renewals or based on requests from other devices, such that renewal times are offset by random delays to avoid excessive network traffic. Controllers may determine which credential is valid for any given time, based on a cryptographically secure key associated with that time and information identifying the entity that is associated with that credential.

摘要： A system and method for controlling access to a computer provides for loose security within a local network while retaining strong security against external access to the network. In one embodiment, a user has access to trusted nodes in a secured group within an unmanaged network, without being required to choose, enter and remember a login password. To establish such a secure blank password or one-click logon account for the user on a computer, a strong random password is generated and stored, and the account is designated as a blank password account. If the device is part of a secured network group, the strong random password is replicated to the other trusted nodes. When a user with a blank password account wishes to log in to a computer, the stored strong random password is retrieved and the user is authenticated.
