  • Patent number: 6732278
    Abstract: A device for providing access to a remote site is disclosed. Access to the device is gained through an authentication process during which a user password and biometrics are provided to the device. The device also includes a security feature such that only authorized users of the specific device can gain access to it. Once authenticated, the device authorizes access to a remote site (e.g., a web site or a server on a local area network). The communications from the device to the remote site is encrypted and further the hand-held device uses a computer generated password to gain access to the site. In this way, user generated passwords, which are typically simple and infrequently changed, are avoided in favor of a more complex and frequently changed computer generated passwords for site access.

  • Patent number: 6650743
    Abstract: The invention uses the advanced intelligent network to provide caller identification for calls placed over the internet (24). A long distance call placed with an internet carrier results in the originating SSP (14) forwarding the call to an originating POP (22) for the internet carrier. The caller ID information is routed through the signaling system 7 network (16) to the SSP (32) in the terminating network. The call is routed to a terminating POP (26) and then to the SSP (32) in the terminating network. The SSP (32) inserts the caller ID information received through the SS7 network (16) and routes the call to the terminating line (30).

  • Patent number: 6606378
    Abstract: An intelligent network for providing access to a computer network (80) has a number of central office switches (64, 82). Each central office switch (64, 82) is capable of receiving a call to a centrex telephone number and transmitting a query. A service control point (70) is coupled to the central office switches (64, 82) by a SS7 signal link (66). The service control point receives the query and transmits a response to the central office switch (64, 82). A hub switch (75) is coupled to the central office switches (64, 82) and receives the call. The hub switch (75) contains a digital trunk service (76) that combines the call with a number of other calls to form a data stream. The data stream is then transmitted to a computer network node (80).
