Abstract: A system and method of providing a way of providing operating information about software which is operating within a protected processing or operating environment. The present invention includes an encrypted trace log which may be of substantially constant size and which is encrypted as it is created. In the event of an error, the trace log may be selectively engaged in response to a signal (e.g., in the event of an error or other anomaly or an operator command) and then removed from the protected processing environment and provided in its encrypted form to a central processing location which possesses the decrypting key. Once the trace log is decrypted, the events may be analyzed to determine if an error has occurred and how to correct it.

Abstract: An end-user system for the blocking of recording digital content at during the rendering of encrypted digital multimedia files. Before the process of rendering of encrypted digital multimedia can be started all rendered media stream during playback are opened to ensure that this multimedia content is not recorded. This blocks the usage of the multimedia interfaces including devices and/or ports that can be used to store un-encrypted content that has been decrypted for the purposes of playing or rendering. The method also includes an exception, which allows recording with permission from the present invention.

Abstract: Embodiments of the present invention provide a method, system and computer program product for protecting digital content through visual proxy transparency control. In an embodiment of the invention, a method for digital content access control for multi-party rights management can be provided. The method can include creating a transparent overlay window over a target window, identifying permissions associated with digital rights management (DRM) protected content rendered in the target window, intercepting in the transparent overlay window a user interface event for a portion of the target window displaying the DRM protected content, and quashing the user interface event if permissions associated with the DRM protected content do not allow access to the DRM protected content, but otherwise passing the event to an event handler for the target window.

Abstract: Embodiments of the present invention provide for flexible monitoring of content. The content at a client device can be monitored based on the use and actions performed by the client. In order to monitor the content at the client, a dependency is created between any recipient of the content and a monitor installed at the client device. For example, the content may be encrypted and, when the content is accessed by a potential recipient, the recipient may be required to request a key from the monitor. This activates the monitor to begin recording transaction data and events about the content's use, such as the recipient's identity and the type of actions performed. The monitor can be configured to passively monitor and record the use of the content at the client's device. In addition, the monitor can be configured to provide audit data that indicates the transaction data recorded to a server.

Abstract: Embodiments of the present invention address deficiencies of the art in respect to graphical user interfaces and provide a novel and non-obvious system for managing data gathered on a computer. In one embodiment of the invention, the method includes executing a first application in a foreground of the computer and a second application in a background of the computer. The method further includes displaying a user interface metaphor for the second application. The method further includes receiving a command to direct a selection of data from the first application to the second application, while maintaining the first application in the foreground of the computer. The method further includes directing the selection of data to the second application, while maintaining the first application in the foreground of the computer.

Abstract: A ballistic logic gate is disclosed. The ballistic logic gate may include an etched silicon substrate with a pair of etched silicon triangular baffles defining input channels. An electron may travel through the input channels toward a nano-deflector with a parabolic deflection surface. The parabolic deflection surface may guide electrons into a fixed path of an output channel toward an output terminal for performing a logic function.

Abstract: A ballistic memory cell structure employing ballistic transistor technology for switching between a read state and a store state is disclosed. The memory cell structure includes substrate structures forming a side wall and a main chamber for defining a linear ballistic channel between the two. The main chamber is formed to include a deflection channel with deflective surfaces to deflect an electron emitted from an electron source into the memory cell structure. Deflection controllers are coupled to the substrate structures for generating biasing fields that adjust the trajectory of electrons flowing through the linear ballistic channel and the deflection channel. Logic output terminals are positioned beyond channel exits for registering exiting electrons and determining a read or store state.

Abstract: A method, system and computer readable medium for the blocking of recording digital content at an end user multimedia end-user-system during the rendering of encrypted digital multimedia files. Before the process of rendering of encrypted digital multimedia can be started all rendered media stream during playback are opened to ensure that this multimedia content is not recorded. This blocks the usage of the multimedia interfaces including devices and/or ports that can be used to store un-encrypted content that has been decrypted for the purposes of playing or rendering.

Abstract: The invention provides a method and system for exchanging data between devices. In one embodiment, the invention includes a system for obtaining biometric data from a user; a system for using the biometric data as a secure key for encrypting and decrypting data; a system for transferring the secure key from a first device in contact with the user to a second device in contact with the user; and exchanging data between the first device and the second device, wherein the biometric data include biometric data from more than one source.

Abstract: The present invention, according to a preferred embodiment, provides an efficient and easy-to-implement method to use existing DRM (Digital Rights Management) systems with existing media players. The present invention separates the enforcement of digital rights independent of the content-rendering software. Unlike many of the prior art systems, the present invention works with any non-DRM player. In one embodiment, the present invention enforces behavior restrictions on an application on an information processing system, which includes loading a dynamic instrumentation (DI) codemonitor. An entry point for an application is retrieved by inserting an instrumentation point thereinto. The instrumentation point is inserted in accordance with the entry point, wherein the instrumentation point causes a branch into the DI code monitor when executed. Depending on the application with the instrumentation point therein, the DI code monitor blocks a request made by the application code.
