A manufacturing entity provides a blinded signature to a secure device and associates a time with the blinded signature. If a signing key is compromised, the manufacturing entity provides a time of the compromise and the time associated with the blinded signature to the replacement authority.

According to an embodiment of the invention, a method and apparatus for session key exchange are described. An embodiment of a method comprises requesting a service for a platform; certifying the use of the service for one or more acceptable configurations of the platform; and receiving a session key for a session of the service, the service being limited to the one or more acceptable configurations of the platform.

To protect a private cryptographic key, two values are derived. The two values together can reconstruct the key. One value is sent to a server and deleted from the local machine. The other value is held by the local machine. To use the key, the user will enter a password, which will be used to authenticate the user to the server, and retrieve the value from the server. The password is also used to unlock the value held by the local machine. The private cryptographic key is thus protected against brute force password attacks without changing the behavior of the user.

A ribbon for accessing an application user interface may be provided. The ribbon may be displayed on a computer in association with the application user interface. The ribbon may include a horizontal scrolling gallery. The horizontal scrolling gallery may display a subset of available options which may be utilized to perform one or more actions with respect to content displayed in the application user interface. An input may be received by the computer to navigate through the available options in the horizontal scrolling gallery.

An embodiment of the present invention provides a method of offering anonymous incentive based context to service providers, comprising delivering context information of a user to the service provider, wherein prior to delivery of the context information to the service provider, the context is anonymized by removing identifying information and aggregating it with context from additional users.

An embodiment of the present invention provides a method of offering incentive based context to service providers, comprising securely capturing private context information of a user and distributing the approved context information to the service provider, wherein the service provider provides an incentive to the user for the context information.
摘要:
Data in a file is read to virtual, autonomous, hierarchically structured object classes that are independent of an application implementation. The object classes are navigable and/or actionable allowing various operations including, but not limited to, validation, integrity testing, “file open”, and file repair at the data level. By rendering a complete picture of the data including relationships before it is actually consumed by an application, security and robustness of applications can be enhanced.

The invention provides a method of separating from corn fiber a lipid fraction having phytosterol esters and phytosterols where the method has the steps of: (a) heating an aqueous mixture of unground corn fiber; (b) contacting the mixture of step (a) with at least one enzyme suitable for digesting starch for a time and at a temperature suitable to provide a mixture of an essentially destarched corn fiber and a liquid comprising soluble carbohydrates; (c) contacting the mixture of step (a) or (b) with a protease enzyme to provide a proteolyzed corn fiber and a liquid; (d) separating the liquid of step (c) from the corn fiber to provide a destarched, proteolyzed corn fiber; and (e) extracting the destarched, proteolyzed corn fiber with at least one organic solvent. A corn fiber lipid fraction/organic solvent solution having phytosterol esters and phytosterols is provided. The invention also provides a corn fiber lipid fraction containing phytosterols and phytosterol esters obtained via solvent extraction of a proteolyzed corn fiber. The concentration of phytosterols and phytosterol esters in the lipid fraction is at least about 1.4 times greater than the concentration of phytosterols and phytosterol esters in the lipid fraction of a nonproteolyzed corn fiber.
