摘要： Content revocation is achieved by disabling licenses issued to a computing device for the content. A content revocation is delivered within a license to the computing device. Upon license storage the content revocation is recognized, validated, and stored in a secure state store under the public key of the content server (PU-CS) that issued the content. Each license has a (PU-CS) therein, and each license evaluation considers each content revocation stored in the state store and having the same (PU-CS). The license is disabled or otherwise affected based on the considered content revocation. A content revocation is one form of a license modification that may be delivered within a license.

摘要： An apparatus is disclosed for performing dynamic synchronization between data stored in a handheld computer and a host computer, each having a plurality of data sets including at least one common data set, each computer having a copy of the common data set. The handheld computer has a processor, a communication port, and a data synchronization engine. The data synchronization engine has a pseudo-cache and one or more tags connected to the pseudo cache. Data is synchronized whenever data is written to main memory and/or when the associated pseudo-cache tag is invalidated. By strict adherence to a set of protocols, data coherency is achieved because the system always knows who owns the data, who has a copy of the data, and who has modified the data. The data synchronization engine resolves any differences in the copies and allows the storage of identical copies of the common data set in the host computer and in the handheld computer.
摘要翻译：公开了一种用于在存储在手持式计算机中的数据与主计算机之间进行动态同步的装置，每个主机具有包括至少一个公共数据集的多个数据集，每个计算机具有公共数据集的副本。手持式计算机具有处理器，通信端口和数据同步引擎。数据同步引擎具有伪缓存和连接到伪缓存的一个或多个标签。当数据被写入主存储器和/或相关联的伪高速缓存标签无效时，数据是同步的。通过严格遵守一组协议，实现数据一致性，因为系统总是知道谁拥有数据，谁拥有数据副本，以及谁修改了数据。数据同步引擎解决副本中的任何差异，并允许在主机和手持计算机中存储公用数据集的相同副本。
