A method and system for secure Voice over Internet Protocol (IP) (VoIP) communications. The method and system provide secure VoIP voice calls, video, Instant Messaging (IM), Short Message Services (SMS), or Peer-to-Peer (P2P) communications while maintaining privacy over the Internet and other communications networks such as the pubic switched telephone network (PSTN) to and from any network device through a virtual private network infrastructure interconnecting private VoIP network devices. The method and system allow a network device to function as an IP private branch exchange (PBX) or a private VoIP gateway and provide and control VoIP voice communications without using other public or private VoIP gateways or VoIP servers or devices on a communications network such as the PSTN or the Internet.

Systems and methods providing for secure voice print authentication over a network are disclosed herein. During an enrollment stage, a client's voice is recorded and characteristics of the recording are used to create and store a voice print. When an enrolled client seeks access to secure information over a network, a sample voice recording is created. The sample voice recording is compared to at least one voice print. If a match is found, the client is authenticated and granted access to secure information.

Systems and methods providing for a dual use voice analysis system are disclosed herein.

A method of sending streamed data over an IP network from a first node 1 to a second node 4, the method comprising using Internet Key Exchange (IKE) to establish an IKE security association (SA) between the first and second nodes 1,4. A shared secret is established between the first and second nodes using the IKE SA, and the streamed data encrypted at the first node 1 with a cipher using the shared secret or a key derived using the shared secret. IP datagrams are constructed containing in their payload, segments of the encrypted streamed data, the datagrams not including an IPSec header or headers. The IP datagrams are then sent from the first node 1 to the second node 4.

In one embodiment, a method includes enrolling a potential enrollee for an identity-monitoring service. The enrolling includes acquiring personally-identifying information (PII) and capturing a voiceprint. Following successful completion of the enrolling, the potential enrollee is an enrollee. The method further includes, responsive to an identified suspicious event related to the PII, creating an identity alert, establishing voice communication with an individual purporting to be the enrollee, and performing voice-biometric verification of the individual. The voice-biometric verification includes comparing one or more spoken utterances with the voiceprint. Following successful completion of the voice-biometric verification, the individual is a verified enrollee. In addition, the method includes authorizing delivery of the identity alert to the verified enrollee.

A method, apparatus and computer product for masking speech. The system includes a signal acquiring apparatus for generating an electrical signal representative of the speech; a processing apparatus for using the electrical signal to provide an audio signal which cancels the speech; and a signal generator, also referred to as a babble generator, for providing a speech masking signal to mask any speech not canceled. The masking signal is generated by processing the speech in one of several ways so that its content is not intelligible.

The present invention provides a secure voice solution for the BlackBerry 9000 (BlackBerry Bold™) Rather than make encrypted voice calls through traditional GSM cellular phone calls, the present invention instead receives voice data from the user using the device microphone and built-in media player software in the device. This data is then encrypted and then sent as an IP packet. The device then receives, as IP packets, encrypted voice communication from the other party in the encrypted call, which in turn are decrypted in the device and then played back on a second media player running on the device. The present invention takes advantage of the device's ability to run two media players simultaneously to in effect, simulate a cellular telephone call. As a result, an encrypted call can be made with PDA-type devices such as the Blackberry@ and also such calls can be made using different data paths (cellular, WiFi, Bluetooth, or the like) as the calls are made by sending and receiving data over the Internet, not as traditional cellular data signals.

It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

The invention discloses a mobile communication system and a voice call encryption method in the mobile communication system, and belongs to the technical field of mobile communication. In the mobile communication system, a calling terminal generates a voice key for voice encryption/decryption, and the voice key is encrypted by using a shared key factor of the calling terminal and then transmitted to a network side; the network side decrypts the encrypted voice key according to the shared key factor of the calling terminal, encrypts the voice key by using a shared key factor of a called terminal and transmits the encrypted voice key to the called terminal; and the called terminal decrypts the encrypted voice key by using the shared key factor of the called terminal, and acquires the voice key. The calling terminal and the called terminal perform encrypted voice call by using the voice key. The voice key used by voice communication can be encrypted and transmitted, and the calling and called terminals perform more secure voice call by using the shared voice key.

A simple and flexible over-air protocol for use with a mobile telephone system, having hand-held telephones in a microcell or other type of cellular communication system. A method in which user stations communicate with one or more base stations to place and receive telephone calls, in which the user stations are provided a secure voice or data link and have the ability to handoff calls between base stations while such calls are in progress. Each base station has a set of “air channels” to which it transmits in sequence. The air channels supported by each base station are called that base station's “polling loop”. A user station receives general polling information on an unoccupied air channel, transmits responsive information to the base station, and awaits acknowledgment from the base station. Each base station may therefore simultaneously maintain communication with as many user stations as there are air channels in its polling loop. The ability of a user station to communicate on any unoccupied air channel makes the protocol air-channel agile, while the stability of user station and base station clocks may define air channels, gaps, and minor frames.
