    摘要: A device for limiting access to information corresponding to a context. The device has context logic configured to determine context and a trusted computing platform coupled to the context logic. The trusted computing has a computer readable medium and a filter coupled to the computer readable medium. The filter is configured to receive context from the context logic and retrieve context information from the computer readable medium associated with the context. Thus, the trusted platform limits access to the context information in the database unless context associated with the context information is received.

    摘要: A method, system, and apparatus for minimizing run-time exception handling overhead from invoked function calls. The present invention novelly minimizes execution of exception checking code and exception handling code in a caller when the callee is a compiled method. In the present embodiment the callee novelly treats the caller as a compiled method thereby enabling the callee to return to the exception handling label of the caller if an exception needs to be handled and to return and continue normal code execution if an exception does not need to be handled. Thereby the present invention minimizes execution of exception handling code in the caller. Further, the present embodiment novelly creates code with the layout of a compiled method when a caller is not a compiled method so that a compiled callee may treat its caller as a compiled method.
