Abstract: A method for adjusting sound data that is transmitted between a first client and a second client is disclosed. The sound data may adjusted or an adjustment indicator that indicates how to adjust the sound data may accompany the sound data. The method comprises determining a proximity between the clients; adjusting the sound data based on the determined proximity; and transmitting the adjusted sound data. The determined proximity may be the physical proximity between the clients or a virtual proximity between virtual representations of the clients. Rules for adjusting sound data based on proximity indicate how to adjust sound characteristics, such as, but not limited to volume and frequency. The rules may also take into account environmental factors such as atmospheric and aquatic environmental factors.

Abstract: Generally described, embodiments of the present invention provide a method system for selectively transmitting data packets of a conversation to clients in a group. A group identifier is associated with a group and data packets exchanged during the conversation are processed and transmitted according to the group identifiers included in the data packet. Clients associated with a device group are determined and a group identifier is created to represent the group. Processing and selectively transmitting data packets exchanged during the conversation according to the group identifiers includes determining the group identifiers contained in a received data packet and transmitting the data packet to the clients having associated with the identified group.

Abstract: Generally described, multimode authentication over a VoIP communication channel is provided. A calling client and a called client may be authenticated for a communication channel establishment. When a calling client requests a call connection with a called client, the calling client is authenticated for the communication channel, based on exchanged contextual information between the calling client and the called client. Likewise, the called client is authenticated for the communication channel by the calling client. Upon authentication, a communication channel is established, over which the calling client and the called client are allowed to exchange more contextual and voice/multimedia information. During a conversation, when a secured service is desired by any of the clients, a series of authentication processes can be performed to grant access to the secured service over the communication channel without loss of the communication channel connection.

Abstract: Generally described, the present invention relates to the identification, extraction, and further use of content contained in a digital voice conversation, such as a Voice over Internet Protocol (VoIP) conversation. More specifically, the present invention relates to the use of “mined” data from a conversation to provide extended services, such as recommendations to individuals participating in a digital voice conversation.

Abstract: A mediation server for controlling contents of incoming and outgoing communication information exchanged as part of a conversation is provided. The mediation server may be a centralized server between an internal (private) network and an external network, utilized for enforcing the internal network's policy and detecting a potential security compromise in the internal network. Predefined evaluation criteria are utilized to enforce internal policy or security policy within the internal network. When communication information is exchanged, the mediation server may monitor potential policy or security breaches in the communication information utilizing the predefined evaluation criteria and execute an appropriate action to prevent potential policy or security breaches.

Abstract: A method and system for collecting and communicating contextual information relating to a VoIP conversation is provided. Structured hierarchies are utilized for efficient communications of various amounts and types of contextual information relating to a VoIP conversation. Information identifying at least one structured hierarchy, which will be used to carry the contextual information, is transmitted during establishment of a conversation between two VoIP enhanced devices. The structured hierarchy is selected from a set of predefined and declared structured hierarchies. Subsequently transmitted contextual information exchanged between two VoIP enhanced devices is represented in accordance with the identified structural hierarchy. VoIP clients, network infrastructure, and various service providers can collect the contextual information based on the identified structured hierarchy, update the contextual information by adding, deleting and/or modifying the contextual data.

Abstract: Generally described, the present invention is directed to a method and system that provides the ability to record and store a digital conversation exchanged among mutually agreed parties in a specified archive database. In some instances, content of a digital conversations may be stored (e.g., for legal and/or medical purposes) along with the authenticity of those conversations. Parties who are involved in the digital conversation can authenticate and associate themselves with the conversation. The authentication may be integrated or bound with the digital conversation so that the digital conversation can be stored with a proof of authenticity in the specified archive database. The stored conversation may be retrieved by the parties or any entity with a delegation from the party for reviewing the conversation, or incorporating new information into the stored conversation.

Abstract: Generally described, the present invention relates to a method and system that provides the ability to digitally sign or authenticate a digital conversation and provides the ability to enable another entity to act on someone's behalf. More specifically, in some instances, digital conversations may be stored (e.g., for legal and/or medical purposes) and the authenticity of those digital conversations may be critical. Embodiments of the present invention provide the ability for the parties involved in the digital conversation to authenticate and associate themselves with the conversation and that authentication may be integrated or bound with the digital conversation.
