Claim One:
1. An identification method, comprising: causing an identification system to enter a fingerprint capturing mode; while the identification system is in the fingerprint capturing mode, capturing a two-dimensional fingerprint image of a person's finger contacting an input surface; while the identification system is in the fingerprint capturing mode, converting the two-dimensional fingerprint image into candidate fingerprint data; while the identification system is in the fingerprint capturing mode, comparing the candidate fingerprint data with each reference fingerprint data in a set of reference fingerprint data; based on the comparison of the candidate fingerprint data with the set of reference fingerprint data, identifying a first reference fingerprint data that matches the candidate fingerprint data more than any other reference fingerprint data in the set of reference fingerprint data, the first reference fingerprint data corresponding to reference fingerprint data of a first enrolled person; after identifying the first reference fingerprint data, causing the identification system to enter a navigation mode; while the identification system is in the navigation mode, capturing finger trace data of a movement of the person's finger relative to the input surface as the person's finger moves relative to the input surface; converting the finger trace data into a sequence of directional symbols to form a candidate trace data passcode; mapping the candidate trace data passcode into a candidate personal identifier; obtaining a reference personal identifier associated with the first enrolled person identified during the fingerprint capturing mode; comparing the candidate personal identifier with the reference personal identifier; and determining that the person corresponds to the first enrolled person only if the candidate personal identifier matches the reference personal identifier.
