The present invention includes a system, method, and device for providing secure operating environments for computer systems. In one form, a method for providing a secure operating environment for a network accessible system is disclosed. The method includes accessing a delay timer having a delay time interval operably coupled to a communication module. The delay time interval may be compared to activity operably associated with the system communicating with the network. The communication module may be enabled in response to the comparison and in one form may be isolated if the communication port remains idle for a time period greater than the delay time interval.

A device, system, and method for capturing email borne viruses are disclosed. In one form an input device such as a keyboard, coupled to a system includes an email function button and a identification key uniquely identifying the keyboard. The keyboard's identification key may be used with a system's email software program to authenticate the origin of initiation of an email communication.

The present invention includes a system, method, and device for securely communicating information Via a DSL Network. In one form, a device operable to provide secure communication of information via the network includes a communication module operable to communicate with a network multiplexer and a security module coupled to the communication module. The security module provides secure communication of information between the communication module and the network multiplexer.

A secure telecommunication systemis provided that allows for communication between a deviceand a receiving deviceof encrypted data messages through a data communications network. The deviceutilizes an encryption decryption enginewhich is operable to execute a plurality of encryption algorithms. The encryption algorithms can be accessed using a key value that is used to access an encryption selection table. The encryption selection tablecan indicate a number of encryption algorithms to be applied in sequence.

Secure messaging communication system

The present invention is directed towards a method, device, and network for providing secure communication environments. In one form, a communication network operable to provide a secure communication environment is disclosed. The communication network includes a communication device operable to request the secure communication environment. The communication network further includes a communication server operable to be coupled to the communication device to enable the secure communication environment.

Method, device, and network for providing secure communication environments

A method and apparatus for performing speaker verification with speaker verification templates are disclosed. A verification unit receives an utterance from a speaker. The verification unit identifies a command associated with the utterance by performing speaker independent recognition. If a speaker verification template associated with the identified command includes adequate verification data, the verification unit eliminates a prompt for a password and verifies the speaker identity by comparing the utterance with a speaker verification template associated with the identified command.

A secure real time voice communication systemis provided that allows for the secure transmission of voice communications between a sending deviceand a receiving devicethrough the public switch telephone network. The deviceuses an encryption decryption enginewhich is capable of executing a number of encryption algorithms which are selected using an encryption selection table. An encryption key can be calculated from a periodic key value and a public variable key value. Further, the encryption algorithm used can be periodically changed during a voice communication session so that multiple encryption techniques can be used within the same communication session.

According to one embodiment of the invention, a method for providing fiber optic cable to an end user includes disposing the fiber optic cable having first and second ends within a sewer line coupled to a premises of the end user, and coupling the first end of the fiber optic cable to a network interface device inside the premises. The method may further include disposing an optical splitter within a main sewer line coupled to the sewer line and coupling the second end of the fiber optic cable to the optical splitter.

A voice activated dialing system includes a database maintaining a plurality of speech templates, associated telephone numbers, and recordings, wherein multiple speech templates can be linked to a single master recording. Processing circuitry compares an utterance from a user to one or more of the templates from the database to find a matching template. When a match is found, the processing circuitry retrieves the telephone number associated with the matching template and the corresponding recording. The recording is replayed to the user prior to initiating a connection to the associated telephone number. Master recordings can be used for multiple entries which are associated with a single telephone number to reduce storage requirements.

Voice activated dialing with reduced storage requirements

A method and apparatus employing voice identification techniques to ensure only authorized users obtain remote access to a data base or computer system. Potential users dial an access number and speak to a security system using a standard telephone. The security system compares the real time voice input to a previously recorded voice print obtained from the authorized user. If the comparison scores high enough to meet a previously established criteria, the user is identified as the authorized user who submitted the previously recorded voice print and the security system then permits the user to access the data base or computer system. The present invention transmits both the users's analog and digital information along a single line to a publicly switched telephone network (PSTN), and therefore is capable of use in currently existing and common telephone lines.

Method and apparatus for accessing a data base via speaker/voice verification

A voice enhanced phone card which allows a caller to place a call by voice activated dialing only when the caller desires it is presented. A caller places a call using a standard calling card switch number and enters a predetermined service code. The voice enhanced phone card system recognizes the service code, and using known telephone switching capabilities, switches the call to a voice activated dialing system at a main feature point in the voice activated dialing system call flow. The call is then connected to a destination using the voice activated dialing routine.
