Abstract
The invention relates to systems and methods for using a template in the authentication process using biometric data. In one embodiment, a module modifies a template of the reference set of biometric data with the candidate set of biometric data when the user is authenticated. In another embodiment, a module modifies a copy of the template of the reference biometric data with modification data thereby creating a challenge template. The client compares the challenge template to a candidate set of biometric data thereby creating a response vector. A module authenticates the user based on the response vector and the modification data.
Claims21
A method for authentication using biometrics, the method comprising:
- providing, at a server, a reference template with a reference set of biometric data associated with an individual;
- receiving, at the server, an authentication request from a client associated with a user;
- generating a copy of the reference template;
- in response to receiving the authentication request, modifying the copy of the reference template with modification data to generate a challenge template, and transmitting the challenge template from the server to the client;
- receiving a response vector based at least in part on the challenge template and a candidate set of biometric data;
- and
- authenticating the user as the individual associated with the reference set of biometric data based at least in part on the response vector and the modification data.
A system for authentication using biometrics, the system comprising
- a server device storing:
- a reference template having a reference set of biometric data associated with an individual requesting authentication from a client machine;
- a modification module configured to generate, in response to receiving an authentication request, a copy of the reference template and to modify the copy of the reference template with modification data to generate a challenge template;
- a network interface module configured to receive the authentication request and transmit the challenge template to the client in response thereto;
- and
- an authentication module configured i) to receive a response vector based at least in part on the challenge template and a candidate set of biometric data and ii) to authenticate a user as the registered individual in response to the response vector and the modification data.
An article of manufacture storing computer-readable program portions embodied therein for authentication using biometrics, the article comprising:
- a computer-readable program portion for providing, at a server, a reference template with a reference set of biometric data associated with an individual;
- a computer-readable program portion for receiving, at a server, an authentication request, from a client associated with a user;
- a computer-readable program portion for generating a copy of the reference template;
- a computer-readable program portion for modifying the copy of the reference template with modification data to generate a challenge template in response to receiving the authentication request;
- a computer-readable program portion for transmitting the challenge template from the server to the client;
- a computer-readable program portion for receiving a response vector based at least in part on the challenge template and a candidate set of biometric data;
- and
- a computer-readable program portion for authenticating the user as the registered individual based at least in part on the response vector and the modification data.
