Secure wireless communication user identification by voice recognition
First Claim
1. A data communications system comprising a wide area data communications network that is bidirectionally coupled to a mobile station through a wireless telecommunication system, said wide area data communications network comprising a plurality of unrelated servers that are accessible by a user of said mobile station, said wide area data communications network comprising at least one user authentication server that functions to authenticate the user prior to the user being granted access to an individual one of said plurality of unrelated servers and for signaling to a selected one of said plurality of unrelated servers that the user is an authenticated user, said user authentication server having access to a database that stores data representing prerecorded user speech characteristics that are obtained from the user in response to a set of reference stimuli, and comprising a comparison function, responsive to the user attempting to access a selected one of said plurality of unrelated servers, for causing the user to be presented with at least one of the reference stimuli, for receiving data from the wireless telecommunication system that is expressive of the user'"'"'s vocal response to the presented at least one reference stimuli, for comparing the received data to corresponding prerecorded user speech characteristics in said database and, upon a match occurring, for signaling the selected one of the plurality of unrelated servers that the user is an authenticated user.

Abstract
A method to authorize or authenticate a user of a wireless telecommunication system (32), and includes steps of (a) selecting a word at random from a set of reference words, or synthesizing a reference word; (b) prompting the user to speak the reference word; and (c) authenticating the user to operate in, or through, or with a resource reachable through the wireless telecommunication system, only if the user'"'"'s speech characteristics match pre-stored characteristics associated with the reference word. In one embodiment the steps of selecting or synthesizing, prompting, and authenticating are performed in a mobile station (10) having a speech transducer (19) for inputting the user'"'"'s speech, while in another embodiment at least one of the steps of selecting or synthesizing, prompting, and authenticating are performed in a wireless telecommunications network (32) that is coupled between the mobile station and a telephone network (35). In yet another embodiment at least one of these steps are performed in a data communications network resource (38) that is coupled through a data communications network (37), such as the Internet, and the wireless telecommunications network to the mobile station. The step of prompting may include a step of displaying alphanumeric text and/or a graphical image to the user using a display (20) of the mobile station.

4. A wireless telecommunication system, comprising:
-
at least one base station;
at least one mobile station comprising a transceiver for conducting wireless communications with said base station, said mobile station further comprising a user interface that includes a visual display and a microphone for inputting a users'"'"'s speech;
a first subsystem coupled to said user interface for prompting the user to speak a reference word that is randomly selected from a set of reference words, or that is randomly generated, said first subsystem operating so as to present the user with a graphical image on said visual display that has been predetermined to elicit a predetermined response from the user that is the selected word; and
a second subsystem coupled to said microphone for authenticating the mobile station to operate in the wireless telecommunications system, or through the wireless telecommunications system, or with a resource that is reachable through the wireless telecommunication system, only if the user'"'"'s speech characteristics match expected characteristics associated with the reference word. - View Dependent Claims (5, 6, 7, 8, 9, 10)

11. A method to authenticate a user of a wireless telecommunication system, comprising steps of:
-
selecting a phrase from a set of reference phrases, the selected phrase comprising at least one word;
prompting the user to speak the selected phrase by presenting the user with a graphical image that has been predetermined to elicit the selected phrase from the user; and
authenticating the user to operate in, or through, or with a resource reachable through the wireless telecommunication system, only if the user'"'"'s speech characteristics match characteristics associated with the selected phrase. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A method to authenticate a user of a wireless telecommunication system, comprising steps of:
-
selecting a word at random from a set of reference words;
prompting the user to speak the selected word by presenting the user with a graphical image that has been predetermined to elicit a predetermined response from the user that is the selected word; and
authenticating the user to operate in, or through, or with a resource reachable through the wireless telecommunication system, only if the user'"'"'s speech characteristics match pre-stored characteristics associated with the selected word. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26)
