  • Patent number: 8051469
    Abstract: A cryptographic session key is utilized to maintain security of a digital identity. The session key is valid only for a limited period of time. Additional security is provided via a bimodal credential allowing different levels of access to the digital identify. An identity token contains pertinent information associated with the digital identity. The identity token is encrypted utilizing public-key cryptography. An identifier utilized to verify the validity of the digital identity is encrypted with the cryptographic session key. The encrypted identity token and the encrypted identifier are provided to a service for example. The service decrypts the encrypted identity token utilizing public key cryptography, and decrypts, with the cryptographic session key obtained from the identity token, the encrypted identifier. If the identifier is determined to be valid, the transaction proceeds normally. If the identifier is determined to be invalid, the transaction is halted.

  • Patent number: 7860989
    Abstract: In a computerized system, a sending computer system and recipient computer system exchange an interchange format message in a resource-efficient manner. For example, a transformation writer at the sending computer system selects and transforms only one or few of a plurality of units of the message at the time. The transformed message units are then streamed to the recipient computer system in accordance with a relevant transformation standard, such as the canonicalization standard in the case of XML messages. A transformation reader at the recipient computer system transforms the messages using a buffer big enough for received message units, and passes the transformed units to a file. Thus, the transformation writer acts as a stream writer to pass a message, and the transformation reader acts as a stream reader at the recipient computer system.

  • Patent number: 7836489
    Abstract: The present invention extends to methods, systems, and computer program products for selecting policy for compatible communication. Hierarchical policy document data structures represent communication (e.g., security) aspects and options such that lower aspects and options are accessed in the context of corresponding higher aspects and options to define applicable scope. Use of a hierarchical description also facilitates separation of what is being protected from how it is being protected thereby allowing security policy to be considered at different locations of a description document.

  • Publication number: 20100162275
    Abstract: The present invention extends to methods, systems, and computer program products for controlling applications through inter-process communication. Applications are extended with application specific extensibility points. The application specific extensibility points permit applications that natively lack inter-process communication capabilities to participate in inter-process communication. Application specific extensibility points can provide an application with a Web based interface thereby making the functionality of the application available to other Web services and other extended applications. Accordingly, application specific extensibility points extend the functionality of applications to interoperate and be integrated with other Web services and other extended applications.

  • Publication number: 20100088672
    Abstract: The subject disclosure relates to a syntax for a scripting language that allows data intensive applications to be written in a compact, human friendly, textual format. The scripting language can be a declarative programming language, such as the ā€œDā€ programming language, which is well suited to the authoring of data intensive programs. A compact query syntax is provided for D that simplifies the expression of complex and data intensive programs. In another non-limiting aspect, conventional operator precedence is modified to accommodate the compact syntax and other unique features of a general purpose declarative programming language.
