A sensitive display system is described. The sensitive display system allows for mediation of content provided from a source to a recipient, such as from a web server to a web browser. Mediation may involve intercepting and augmenting the content so as to restrict or otherwise control information displayed on a display of the recipient device. In this way, the sensitive display system allows restricted information to be replaced with security status messages, or removed entirely. For example, when a user comes within a specified distance from the sensitive display area, a security classification level of the approaching user is used to determine whether there should be any change in the display. If so, a mediating device causes a browser push to occur, to thereby block or otherwise restrict some or all of the display.

Sensitive display system

A content based messaging audio and video conferencing system provides a messaging infrastructure for multimedia and collaborative applications. The audio/video conferencing system may be implemented using a publish/subscribe infrastructure, such as a content-based messaging (CBM) infrastructure and system. Conference participants may exchange audio and/or video data streams using the CBM system. A list of contacts displays the current status of users. For example, the status of a user may be offline, online, and in a conference. The conference system uses the publish/subscribe infrastructure to provide instant state changes in the contact list using published updates to generate state messages for those users subscribing to contacts using the conference system.

Audio/video-conferencing using content based messaging

Methods and systems for enriching information streams with supplemental content are disclosed. A contextual publisher may eavesdrop on an information distribution service, such as a news wire, and detect the presence of particular messages having subject matter in which the contextual publisher has expertise. The contextual publisher may thus generate content that is supplemental to the messages, and forward this supplemental content to the original recipients of the messages. In this way, users may receive timely information about topics in which they have a current interest.

Enriching information streams with contextual content

A publish-subscribe system includes a producer configured to publish a message and to subscribe to an acknowledgement that the message was received. The system also includes a consumer configured to subscribe to the message and to publish the acknowledgement. The system further includes a network configured to register a message subscription and an acknowledgement subscription, to process the message subscription and the acknowledgement subscription, to forward the message to the consumer based on the message subscription and to forward the acknowledgement to the producer based on the acknowledgement subscription.

Publish-subscribe system having a reliability mechanism

A content based messaging-remote procedure call (CBM-RPC) protocol is provided as an extension of a CBM system that allows an application to directly access a remote procedure and, for example, obtain data returned by the procedure (e.g., stored in an associated database or storage device). An application may specify a procedure name (e.g., a unique identification (ID), such as a uniform resource identification (URI)) and parameters (e.g., a list of name/value-pairs) in a request (or a CBM-RPC), which is published to a CBM network. One or more, procedures or functions may subscribe to the request and generate responses (e.g., the requested information or a fault if the request is not valid) that are published to the CBM network.
