Methods, systems, devices, and products for authenticating users

摘要

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.

1. 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.
