Abstract: This disclosure describes embodiments of systems and methods that use protocols and techniques that can stream audio from a video device to a separate device while reducing or eliminate audio/video synchronization errors. In some embodiments, these systems and methods use Voice over IP (VoIP) technology to stream audio to mobile devices with low latency, resulting in little or no user-perceivable delay between the audio stream and corresponding video presentation. As a result, users can enjoy both the audio and video of any video display in an establishment. In addition, the systems and methods described herein may be implemented in the home or other locations to allow viewers who may be hard of hearing to listen to audio clearly via headphones.

Abstract: An etchant for dielectrics, such as silicon dioxide, that leaves monocrystalline silicon surface exposed by the etchant free of etch damage, such as etch pits, when the etch is done in the presence of transition metals, such as copper, tungsten, titanium, gold, etc. The etchant comprises hydrofluoric acid and a source of halide anion, such as hydrochloric acid or a metal-halide. The etchant is useful in microelectromechanical system device fabrication and in deprocessing integrated circuits or the like.

Abstract: A system for automating the recovery of a credential store, in which client software generates a temporary key pair based on a new password, and sends client information including the user's name, the public half of the temporary key pair, and the host name of the client computer system to a server system, from which the client information is passed to a recovery process. The client software process displays a prompt indicating that the user should call a help desk. A help desk administrator verifies the user's identity and approves the user's request by causing an approval message to be sent to the recovery process. The recovery process obtains recovery information consisting of either the decryption key(s) for the credential store, or a decrypted copy of the credential store, and encrypts the recovery information using the temporary public key. The client process downloads the recovery information from the server, and decrypts it using private key of the temporary key pair.

Abstract: A method is provided for a enabling a user to initiate a password protected backup copy of the user's credentials. The method includes providing a user with a credential store containing information relating to the user's identity, generating a different recovery password of any length for each recovery authority, encrypting the recovery password for each recovery authority, storing the encrypted recovery passwords in the credential store, and sending a copy of the information by the user from the credential store to a central repository.

Abstract: Embodiments of the present invention address deficiencies of the art in respect to symmetric key generation and provide a method, system and computer program product for symmetric key generation using an asymmetric private key. In one embodiment, a symmetric key generation data processing system can include a symmetric key generator configured with a programmatic interface including an input parameter for a seed, an input parameter for an asymmetric private key, and an output parameter for a symmetric key. The symmetric key generator can include program code enabled to generate the symmetric key by encrypting the seed with the asymmetric private key.

Abstract: The present invention is a method, system and apparatus for the encryption of a credential store by using a lockbox mechanism. In a credential store encryption method, a lockbox for a credential store can be retrieved and an encryption key can be selected from among a list of encryption keys in the lockbox. The lockbox can be a local lockbox and the local lockbox can be retrieved from an unencrypted region of the credential store. In any case, subsequent to the retrieval of the lockbox, the credential store can be decrypted with the selected encryption key.
