  • Patent number: 9252942
    Abstract: One embodiment of the present invention provides a system for performing secure multiparty cloud computation. During operation, the system receives multiple encrypted datasets from multiple clients. An encrypted dataset associated with a client is encrypted from a corresponding plaintext dataset using a unique, client-specific encryption key. The system re-encrypts the multiple encrypted datasets to a target format, evaluates a function based on the re-encrypted multiple datasets to produce an evaluation outcome, and sends the evaluation outcome to the multiple clients, which are configured to cooperatively decrypt the evaluation outcome to obtain a plaintext evaluation outcome.

  • Publication number: 20150106730
    Abstract: A framework for a screen content sharing system with generalized screen descriptions is described. In one approach, a screen content update message is sent from a client device to a control plane where the client device wishes to share its screen content with a remote device. The remote device sends a message indicating an interest in receiving said update. The control plane subsequently retrieves a detailed description from the client device. Based on the computational context of the remote device, the detailed description may be trimmed to a more compatible format. In some embodiments, the detailed description is sent to the remote device and includes a screen description and a content description. The content of the shared screen is described and the content is subsequently retrieved from a service router. A shared screen content is assembled based on the screen description and the content retrieved from the service router.
