Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A method to verify integrity of information and selectively determine whether the information is authorized to be executed by the platform. The information is downloaded to a platform operating in a pre-boot operational state.

Abstract: A method and apparatus pertaining to annotating a document window on a display device of a computer-based system. An annotation window is displayed over a selected portion of the document window where the annotation window is defined by a transparent window area bounded by a border. The annotation window enables the selected portion of the document window to be visible through the annotation window. Annotations are displayed within the annotation window where the annotations have a transparent background enabling the selected portion of the document windows to be visible through the transparent background of the annotations. When the annotation window is closed, the annotations are embedded into a contained document shown in the document window so that the annotations and the document are visible simultaneously in the selected portion of the document window.

Abstract: A method and apparatus for re-drawing a transparent window on at least one display device of a computer based system having a central processor and a memory is disclosed. Having a transparent window and an underlying second window, it is determined whether the underlying second window is active. If the underlying second window is active, the transparent window is hidden. The underlying second window is re-drawn and the transparent window is shown. Otherwise, the transparent window is maintained.

Abstract: 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.

Abstract: 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.
