Abstract
To authenticate a user, fingerprint data for multiple fingers of the user fingers is sensed by a fingerprint sensor (504). Each of these multiple fingers is situated adjacent to at least one other of these multiple fingers while the fingerprint data is being sensed by the fingerprint sensor. Various characteristics of the user's fingers can be analyzed (506) as part of the user authentication, such as the length of the user's fingers relative to one another, the width of the user's fingers relative to one another, the locations of minutiae of one of the user's fingerprints relative to the locations of minutiae of other of the user's fingerprints, and so forth.
