Abstract
Disclosed herein are systems, computer-implemented methods, and tangible computer-readable media for voice authentication. The method includes receiving a speech sample from a user through an Internet browser for authentication as part of a request for a restricted-access resource, performing a comparison of the received speech sample to a previously established speech profile associated with the user, transmitting an authentication to the network client if the comparison is equal to or greater than a certainty threshold, and transmitting a denial to the network client if the comparison is less than the certainty threshold.
Claims20
1 A computer-implemented method of voice authentication, the method comprising:
- receiving a speech sample from a user through an Internet browser for authentication as part of a request for a restricted-access resource;
- performing a comparison of the received speech sample to a previously established speech profile associated with the user;
- transmitting an authentication to the network client if the comparison is equal to or greater than a certainty threshold;
- and
- transmitting a denial to the network client if the comparison is less than the certainty threshold.
The computer-implemented method of claim 1, wherein the user captures and sends the speech sample with a single user input.
The computer-implemented method of claim 1, wherein a computing device running the Internet browser preauthenticates the received speech sample before sending the speech sample to the server.
The computer-implemented method of claim 1, wherein a received user token must match a previously established user token before transmitting the authentication to the network client.
The computer-implemented method of claim 1, the method further comprising:
- sending to the user with a prompt for an additional speech sample due to feigned poor speech recognition if the comparison is less than the certainty threshold;
- receiving the additional speech sample from the user;
- performing a second comparison of the additional received speech sample to the previously established speech profile associated with the user;
- and
- transmitting an authentication to the network client if the second comparison is equal to or greater than a certainty threshold.
The computer-implemented method of claim 1, wherein the received speech sample is a password.
The computer-implemented method of claim 1, wherein the user reads specified text to generate the speech sample.
A system for voice authentication, the system comprising:
- a module configured to receive a speech sample from a user through an Internet browser for authentication as part of a request for a restricted-access resource;
- a module configured to perform a comparison of the received speech sample to a previously established speech profile associated with the user;
- a module configured to transmit an authentication to the network client if the comparison is equal to or greater than a certainty threshold;
- and
- a module configured to transmit a denial to the network client if the comparison is less than the certainty threshold.
A tangible computer-readable medium storing a computer program having instructions for voice authentication, the instructions comprising:
- receiving a speech sample from a user through an Internet browser for authentication as part of a request for a restricted-access resource;
- performing a comparison of the received speech sample to a previously established speech profile associated with the user;
- transmitting an authentication to the network client if the comparison is equal to or greater than a certainty threshold;
- and
- transmitting a denial to the network client if the comparison is less than the certainty threshold.
