Abstract: Systems and methods may be provided for masking data on public networks, such as social networking sites. At a publishing node, the system may monitor data input fields in a webpage, and intercept and encode content, such as text, images, and video input at the data input fields, prior to the content being posted online on a public service provider's website. A privacy agent may process input field content to try to detect encoding markers in the input field content, which define portions of the content that are to be encoded. A third party key server may be used to store decoding keys. A URI reference to the decoding key may be used to access the decoding key by a node attempting to view the decoded version of the input field content.

Abstract: Data may be masked on public networks, such as social networking sites. At a publishing node, the system may monitor data input fields in a webpage that are processed by an internet browser. The system may intercept data, such as text, images, and video input at the data input fields, prior to the data being posted online. The publishing node may control which users are permitted access to the posted data by defining a policy associated with the data input field. The posted data may be transformed or tokenized to ensure that it is inaccessible to a user (or group of users) unless that user/group has access to the decoding key under the policy. In this way, data security and data control may be provided to a publishing user node. Data that has already been posted may be destroyed, for example, by deleting the decryption key or a token.

Abstract: Systems and methods may be provided for masking data on public networks. At a publishing node, the system may monitor data input fields in a webpage, and intercept and encode content, such as text, images, and video input at the data input fields, prior to the content being posted online on a public service provider's website. A policy may be defined to control which users are permitted access to a key to decode the encoded content. The policy may defer to a third party policy node in determining key access. An account for a controlling entity, such as a guardian or employer, may be configured to control the encoding status of posts made by another. The controlling entity may control who has key access to decode posts made by the other account. The guardian account may be configured to have preemptive rights over posting decisions made by the minor.

The collapsible docking station includes a band that is moveable between a collapsed position where the band forms a wound coil, and a fully expanded position where the band forms a circular ring.

Abstract: A multi-function valve exchange apparatus including an alignment tool for locating tools of the multi-function valve exchange apparatus proximate to an installed cardiovascular valve assembly comprised of a base member and an exchangeable valve member detachably coupled thereto; a stabilizer tool for grabbing the base member and preventing the base member from moving during a procedure for exchanging the existing valve member with a new valve member; removal and collapsing tools for uncoupling and removing the existing valve member; and an installation tool for installing a new exchangeable valve member having a new leaflet set. A method for exchanging a valve member uses the multi-function valve exchange apparatus to facilitate removal of the existing exchangeable valve member and installation of the new exchangeable valve member.

Abstract: A transport adapter layer interface (TALI) includes messages, processes, and packet structures for sending and receiving SS7 information over a stream-oriented connection, such as a TCP/IP connection. For example, the TALI interface includes test messages for testing the status of a connection and allow and prohibit messages for enabling and disabling service data communications without invoking a TCP handshaking procedure. The TALI interface also includes SYNC and LENGTH fields for facilitating extraction of individual message packets over a stream-oriented connection.

Abstract: Methods, systems, and computer readable media for providing local application routing at a Diameter node are disclosed. One method includes receiving, at an ingress Diameter message processor associated with a Diameter signaling router (DSR), a Diameter message from a peer Diameter element. At the ingress Diameter message processor, application routing data is accessed to determine whether processing of the Diameter message by a Diameter application is required. In response to determining that Diameter application processing is required, the Diameter message is forwarded to a Diameter message processor hosting a Diameter application identified by the application routing data for processing. In response to determining that Diameter application processing is not required, the Diameter message is forwarded to an egress Diameter message processor associated with the DSR.

Abstract: According to one aspect, the subject matter described herein includes a method for routing Diameter messages. The method includes steps occurring at a Diameter signaling router (DSR) comprising a plurality of Diameter message processors. The method also includes receiving, by a first of the plurality of Diameter message processors and from a first Diameter node, a Diameter message, wherein the Diameter message is received via a first Diameter connection. The method further includes determining, by the first Diameter message processor, a next-hop Diameter node for the Diameter message. The method further includes communicating, by the first of the plurality of Diameter message processors and to a second of the plurality of Diameter message processors, the Diameter message. The method further includes communicating, by the second Diameter message processor and to the next-hop Diameter node, the Diameter message, wherein the Diameter message is communicated via a second Diameter connection.

Abstract: Methods, systems, and computer readable media for source peer capacity-based Diameter load sharing are disclosed. According to one aspect, the subject matter described herein includes a method for source peer capacity-based Diameter load sharing. A network element for processing Diameter messages received from a Diameter peer requests information regarding a Diameter message capacity requirement of the Diameter peer, receives information regarding the Diameter message capacity requirement of the Diameter peer, and uses the received information to load share the processing. In one embodiment, the network element is a Diameter signaling router having multiple message processors for processing Diameter messages, and the information regarding the Diameter message capacity requirement of the Diameter peer is used to load share Diameter message processing and/or Diameter connections among the multiple message processors.

Abstract: Methods, systems, and computer readable media for answer-based routing of Diameter request messages are disclosed. According to one method, a Diameter request message is received from a first Diameter node at a. A copy of at least a portion of the Diameter request message is cached at the DSR and the Diameter request message is routed to a second Diameter node. The DSR determines whether a predetermined condition associated with an answer to the first Diameter request message exists. In response to determining that the predetermined condition exists, the cached portion of the Diameter request message is retrieved, a Diameter request that includes the cached portion of the Diameter request message is generated, and the generated Diameter request message is routed.

Abstract: The subject matter described herein includes methods, systems, and computer readable media for PCRF node selection. According to one aspect, a system for PCRF node selection is provided. The system includes a first PCRF selection node for receiving a first request message for which PCRF node selection is required. The first PCRF selection node determines whether to select the PCRF or to delegate selection of the PCRF. In response to a determination to delegate the selection of the PCRF, the first PCRF selection node generates and sends a second request message related to the first request message. The system further includes a second PCRF node for, in response to receiving the second request message from the first PCRF selection node, determining whether to select the PCRF or to delegate selection of the PCRF. In response to determining to select the PCRF, the second PCRF selection node selects the PCRF.
