摘要： A method and apparatus creates and plays objects and sound synchronously after eliminating the silent segments of the sound. The method inserts sequence marks into the object and sound data, deletes silent segments of the sound data including the sequence marks that reside in the silent segments, and re-inserts the last deleted sequence mark back into the sound data. In so doing, the system detects the silent segments of the recorded sound stream data and deletes the silent portions from the recorded data. Upon replay of an object and its associated sound, any drawing done during the silent segments are played at the computer's full graphics drawing speed, only slowing down to real-time again when more sounds are encountered. Thus, the system plays "fast while silent" and slows to real-time when sounds are played. This saves the space required to stored the recorded sound, and the user does not have to wait through the silent periods.
摘要翻译：一种方法和装置在消除声音的无声段之后同步地创建和播放对象和声音。该方法将序列标记插入对象和声音数据，删除声音数据的静音段，包括驻留在静音段中的序列标记，并将最后删除的序列标记重新插入到声音数据中。在这样做时，系统检测记录的声音流数据的静音段，并从记录的数据中删除无声部分。在重放对象及其相关联的声音时，在静音段中完成的任何绘图都将以计算机的完整图形绘制速度播放，仅在遇到更多声音时再次减慢实时。因此，系统播放“快速而无声”，并且在播放声音时实时减慢。这节省了存储录音的空间所需的空间，用户不必等待静音期。

摘要： A computing system having a security module to validate requests to reconfigure a computing system. The computing system includes a persistent store for holding information indicative of the current trusted authority. A security module executing on the computing system determines whether to grant a request to modify configuration data within the computing system as a function of the information within the persistent store. In one particular embodiment, the security module facilitates the secure transfer of trust from one trusted authority to another, such as from a manufacturer to a customer. In another embodiment the security module validates a request to overwrite configuration data such as the computer's boot image or compact verification data for validating the computer's boot image.

摘要： A method and apparatus for relating (called hyperlinking) a region of one document to one or more regions of other documents. This is provided by using a mechanism for linking and embedding objects to establish the endpoints of the hyperlinks (called anchors) together with the creation of intermediate tables which maintain information about relations between regions of documents and attributes of the relationship. When a user selects a region in a document which participates in a relationship, a database program is invoked which displays information about related regions in other documents which may be accessed through the intermediate tables. An auxiliary table maintains information about attributes which may be custom designed by the user, such as author, date of creation, etc. The intermediate tables allow relationships among multiple regions of documents created by different applications. Relationships are bidirectional in that the user can traverse from any region in a document to any other region in the same relationship.

摘要： A method and apparatus for ensuring system boot image integrity and authenticity is described. In one embodiment, the invention provides security from the end of Basic Input/Output System (BIOS) initialization to the point in time at which control is transferred to a high-level operating system (OS). The OS boot image is obtained via a network connection and is checked for integrity and authority to run on a particular platform. For this purpose, the invention provides a boot image security usage model that is simple and flexible enough to cover a variety of needs. Because receipt of boot images via a network connection can be subject to size constraints, the invention allows software to bootstrap more sophisticated security software if desired. In general, the invention utilizes one or more Remote-Boot Authorization Certificates for each group of platforms to be managed. The authorization certificate for a group of platforms is configured into each of the platforms in a group as the source of authority for allowing boot images to be executed. The authorization certificate is also the source of authority for allowing reconfiguration commands, including reconfiguration commands that transfer the source of authority to another authority. In one embodiment, IT organizations can create different authorization certificates for different groups to allow the different groups to be managed by different authorities. Authority can also be transferred between management groups. The Remote-Boot Authorization Certificates provide protection against remote-boot images that have been damaged and/or tampered with either in transit or on a server, the ability to designate and enforce which boot images are permitted, and a mechanism to limit the scope of management authorities having remote-boot authority.
摘要翻译：描述了一种用于确保系统引导映像完整性和真实性的方法和装置。在一个实施例中，本发明提供从基本输入/输出系统（BIOS）初始化结束到将控制传送到高级操作系统（OS）的时间点的安全性。操作系统引导映像是通过网络连接获得的，并检查其在整个特定平台上的完整性和权限。为此，本发明提供了一种引导映像安全性使用模型，其简单和灵活性足以满足各种需求。由于通过网络连接接收引导映像可能受到大小限制，本发明允许软件在需要时引导更复杂的安全软件。通常，本发明利用一个或多个远程启动授权证书来管理每组平台。将一组平台的授权证书配置为组中的每个平台作为允许启动映像执行的权限的来源。授权证书也是允许重新配置命令的权力来源，包括重新配置命令，将权限的来源转移到另一个权限。在一个实施例中，IT组织可以为不同的组创建不同的授权证书，以允许不同的组由不同的权限管理。管理层也可以在管理组之间转移。远程启动授权证书提供了对在传输或服务器上已损坏和/或篡改的远程启动映像的保护，指定和强制执行哪些启动映像的能力以及限制范围的机制管理机构拥有远程启动权限。

摘要： A system for checking the integrity and authority of information includes a user platform, a communication channel, and a remote platform. The remote platform transmits the information to the user platform via the communication channel. The user platform, which lacks a public key for the information, verifies the authority and integrity of the information by comparing a transformation value of the information generated on the platform to a transformation value supplied by a user. The platform is also capable of authenticating the information by displaying the transformation value generated from the information and requesting that the user match the transformation value generated from the information with a transformation value known to the user.
