1. An enhanced biometric authentication device comprising:
- an input sensor configured to receive composite inputs from a plurality of touch pads, each composite input comprising a biometric component and a mechanical component;
a biometric processing engine communicatively coupled to the input sensor and configured to receive the biometric components and generate a biometric characterization from the biometric components;
a mechanics processing engine communicatively coupled to the input sensor and configured to receive the mechanical components and generate a mechanical characterization from the mechanical components; and
an authentication engine, the authentication engine configured to;
receive the biometric characterization from the biometric processing engine;
receive the mechanical characterization from the biometric processing engine;
compare the biometric characterization and the mechanical characterization to an authentication template to determine whether each of the composite inputs is indicative of a corresponding glyph in the authentication template and whether each of the composite inputs was entered on a correct touch pad; and
authenticate a user based on the comparison.

Abstract
Enhanced biometric authentication is achieved by combining a user'"'"'s inherent biometric data with the user'"'"'s knowledge of a secret glyph. In one embodiment, a touchpad is provided on which the user may use a finger to indicate a plurality of strokes that form a distinct glyph. Image stabilization may be used to extract a readable fingerprint from the strokes, and the glyph and finger print are matched to a stored profile. The glyph may be one or more alphanumeric characters that represent a password. The user can then enter the password on the touch pad with his finger. If the fingerprint and password both match, the user is authenticated.

12. A method of authenticating a user, the method comprising the steps of:
-
receiving a composite input from the user; processing the input to identify a biometric component and a mechanical component; processing the biometric component to create a biometric characterization of the biometric component; processing the mechanical component to create a mechanical characterization of the mechanical component; and determining that the user is authentic by comparing the biometric characterization and mechanical characterization to a previously stored authentication template including a biometric component and a mechanical component; wherein receiving a composite input sample from the user comprises receiving inputs on a plurality of touch pads, the mechanical component of each input describing a glyph; the characterization profile associates each input glyph with one of the plurality of touch pads; and determining that the user is authentic further comprises determining that; each glyph matches a glyph in the authentication template; each glyph was entered on the correct touch pad; and the glyphs were entered in the correct order. - View Dependent Claims (13, 18, 19)

14. A method of providing enhanced security for a system, the method comprising the steps of:
-
creating an authentication template for a known user by; receiving from a first touch pad a first composite input from the known user, the first composite input sample comprising a biometric component and a mechanical component; characterizing the biometric component of the first composite input sample; characterizing the mechanical component of the first composite input sample; storing the characterized biometric component and mechanical component in an authentication template; authenticating an unknown user by; receiving from a second touch pad a second composite input sample from the unknown user, the second composite input sample comprising a biometric component and a mechanical component; characterizing the biometric component; characterizing the mechanical component; comparing the characterized biometric component and mechanical component to the authentication template; and associating the unknown user with the known user if the characterized biometric component and characterized mechanical component match respective characterized biometric and mechanical components of the authentication template within a tolerance. - View Dependent Claims (15, 16, 17)
