Method for providing fingerprint-based shortcut key, machine-readable storage medium, and portable terminal

摘要

A portable terminal provides a fingerprint-based shortcut key to realize both security and one touch convenience. The portable terminal includes a fingerprint sensor for recognizing user's fingerprint, a memory for storing fingerprint data, and a controller for mapping and storing first fingerprint data inputted through the fingerprint sensor and a function of the portable terminal in the memory. Upon input of second fingerprint data through the fingerprint sensor, there is a comparison of the first fingerprint data with the second fingerprint data, and performing the function mapped to the first fingerprint data when the first fingerprint data is identical to the second fingerprint data. The portable terminal may perform the authentication and provide the result to another portable terminal, or an authentication server can perform the comparison.
