    摘要: A file may contain an unencrypted and an encrypted portion. The unencrypted portion may contain a layout section that may point to a published license, metadata, and a contents section, where the contents section is in the encrypted portion. The encrypted portion may contain the contents section which may act as a directory for one or more included files that may be compressed and stored in the encrypted portion. When the file is opened by a receiver, the receiver may read the published license and communicate with a security server to establish access rights and receive at least one key for decrypting at least a portion of the encrypted portion of the file. The receiver may then gain access to the included files.

    摘要: Embodiments are directed to securely filtering trust services records. In one scenario, a client computer system receives at least one of the following trust services records: a trust services certificate, a principal certificate, a group certificate and a trust services policy. The client computer system performs a time validity check to validate the trust services record's timestamp, performs an integrity check to validate the integrity of the trust services record and performs a signature validity check to ensure that the entity claiming to have created the trust services record is the actual creator of the trust services record. The client computer system then, based on the time validity check, the integrity check and the signature validity check, determines that the trust services record is valid and allows a client computer system user to perform a specified task using the validated trust services record.

    摘要: Modular content framework and document format methods and systems are described. The described framework and format define a set of building blocks for composing, packaging, distributing, and rendering document-centered content. These building blocks define a platform-independent framework for document formats that enable software and hardware systems to generate, exchange, and display documents reliably and consistently. The framework and format have been designed in a flexible and extensible fashion. In addition to this general framework and format, a particular format, known as the reach package format, is defined using the general framework. The reach package format is a format for storing paginated documents. The contents of a reach package can be displayed or printed with full fidelity among devices and applications in a wide range of environments and across a wide range of scenarios.
