One embodiment of the present invention provides a system for facilitating custodian-based routing. During operation, the system receives, at a computing device, a request for a piece of content from a user, and determines whether the content is available locally. In response to the content not being available locally, the system identifies a remote custodian device that stores the content. The custodian device is not identified by its physical address. The system then identifies a communication endpoint associated with the identified custodian device, and maps a physical address corresponding to the identified communication endpoint. The system establishes a connection to the communication endpoint using the mapped physical address to obtain the requested content.

The present invention is a method to control communication channels using universal and persistent identifiers in circuit/packet switched or converged networks. The method involves linking domain specific addresses or concrete identifiers of communication end points within or across channels, domains and networks with an abstract, persistent and universal identifier that represents the single point of contact or principal identity of the user. The principal identity can specify parameters of inbound/outbound communication relationships with other specified/unspecified users/entities inter-alia through default/specific levels of control in communication relationships on/across/through normal or alternate channels, domains, applications, networks, etc., based on universal/persistent identifiers such as XRI. All transactions originating from, or terminating on, the principal identity are authenticated, asserted securely and routed automatically to an appropriate channel based on the principal identity's current context (state, location, presence, etc.) and privileges (or contracts) defined in rules created by the principal identity for access, usage, privacy, synchronization, compliance, expiry, etc. The principal identity is also empowered with multi-level control over attributes and metadata including rules for what data to expose/share and what data to eclipse/hide for which user. Control/user data, or traffic, and program/client/sequence logic, may be resident/executed/exchanged/carried on, or across, diverse networks/channels/media/devices/domains etc.

A system and method are provided for detecting extension attacks made to a communication enterprise, and taking appropriate remedial action to prevent ongoing attacks and future attacks. One or more attributes of a suspect call are analyzed, and a risk is associated with each analyzed attribute. An overall risk or assessment is then made of the analyzed attributes, attack attributes are logged, and one or more remedial actions may be triggered as a result of the analyzed call attributes. The remedial actions may include recording the call, notifying an administrator of a suspect call, or isolating the communication enterprise from the attack by terminating the call or shutting down selected communication endpoints to prevent calls being made to those extensions. Rules may be applied to the analyzed attributes in order to trigger the appropriate remedial action. The call attributes analyzed may include call destination, call direction, call type, time of day of the call, call duration, whether a call source is spoofed, call volume from a particular call source, and hash values created for a suspect media stream.

An integrated communications system is provided wherein video conferencing is conducted and participants sharing a video resource may be identified. Application of the present invention is particularly suited for videoconferencing when there are a plurality of communication endpoints, and at least one of the communication endpoints includes multiple participants at the shared video resource. A video or audio processing technique takes place to identify locations of conference participants at the communication endpoints. Each participant has an assigned RFID identifier during the conference. The RFID identifiers are interrogated by an RFID reader that downloads data from the identifiers to the system. The gathered RFID data is then matched with the processed video or audio data in order to identify each of the conference participants. A user interface is provided to allow the participants to view the other remote participants along with the identifying data of the remote participants. The data may include, for example, each remote participant's name displayed directly below the video image of that remote participant. As time progresses during the conference, participant identity is tracked and updated by repeating the video/audio processing technique and repeating the interrogation of the RFID identifiers.

The present invention relates to a multiple access space laser communications optical system. According to the present invention, multiple optical signals containing a number of channels are simultaneously received and demultiplexed at a multiple access communication device. Separate communication signals may be multiplexed by the multiple access communication device, and transmitted through the same or a different telescope optical assembly used to receive communication signals. Double-pass reflection is used to selectively polarize signals and to ensure that signals are substantial normal to optical bandpass filters, to avoid large shifts in the wavelengths transmitted by the optical bandpass filters. The system is capable of providing discrete communications with a number of communication endpoints, regardless of where the communication endpoints are located within the field of view of the telescope optical assembly.

A system for providing spontaneous discovery of remote service profiles is provided. A Bluetooth-enabled communication end point registers the service profiles available on Bluetooth devices in communication with the end point over a personal area network. The end point then translates the service profiles to a format supported over a second network and transmits them to other end points. The other end point then registers the service profiles and translates them to a format understood by Bluetooth devices. Bluetooth devices local to the second end point can then communicate with the remote Bluetooth devices via the translated service profiles.
