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.
Claims20
A system, comprising:
- a processor;
- and
- a memory storing code that when executed causes the processor to perform operations, the operations comprising:
- receiving a composite input comprising an image of a fingerprint extracted from a stroke of an arbitrary glyph drawn by a user on a touch surface;
- generating a mechanical characterization of the arbitrary glyph drawn by the user;
- segregating the composite input into the image of the fingerprint and into the mechanical characterization of the arbitrary glyph;
- comparing the image of the fingerprint to a template for authentication;
- comparing the mechanical characterization to the template for authentication;
- and
- authenticating the user when both the image of the fingerprint and the mechanical characterization match the template for authentication.
A method, comprising:
- receiving, by a processor, a composite input comprising an image of a fingerprint extracted from a stroke of an arbitrary glyph drawn by a finger of a user on a touch surface of a device;
- generating, by the processor, a mechanical characterization of the arbitrary glyph drawn by the finger of the user;
- segregating, by the processor, the composite input into the image of the fingerprint and the mechanical characterization of the arbitrary glyph;
- comparing, by the processor, the image of the fingerprint to a template for authentication;
- comparing, by the processor, the mechanical characterization to the template for authentication;
- and
- authenticating, by the processor, the user in response to a match of both the image of the fingerprint and the mechanical characterization to the template for authentication.
A memory storing instructions that when executed cause a processor to perform operations, the operations comprising:
- receiving a composite input comprising an image of a fingerprint extracted from a stroke of an arbitrary glyph drawn by a finger of a user on a touch surface;
- generating a mechanical characterization of the arbitrary glyph drawn by the finger of the user;
- segregating the composite input into the image of the fingerprint and the mechanical characterization of the arbitrary glyph;
- comparing the image of the fingerprint to a template for authentication;
- comparing the mechanical characterization to the template for authentication;
- and
- authenticating the user in response to a match of both the image of the fingerprint and the mechanical characterization to the template for authentication.
