| 20120098948 | FINGERPRINT AUTHENTICATION APPARATUS HAVING A PLURALITY OF FINGERPRINT SENSORS AND METHOD FOR SAME - A fingerprint authentication apparatus and method which processes fingerprint data input through a plurality of fingerprint sensors and uses the processed fingerprint data in authentication to thereby increase security and performance. The fingerprint authentication apparatus includes a first sensor configured to acquire first fingerprint data from a user; a second sensor configured to acquire second fingerprint data that is different from the first fingerprint data; and a control unit configured to determine whether or not to authenticate the user based on similarities obtained from the comparison of each of the first fingerprint data and the second fingerprint data with registered fingerprint data. | 04-26-2012 |
| 20110286686 | ROLLED FINGERPRINT ACQUISITION APPARATUS AND METHOD USING REGISTRATION AND SYNTHESIS - Provided are a rolled fingerprint acquisition apparatus and method for accurately registering and synthesizing fingerprints. The rolled fingerprint acquisition apparatus selects a reference frame from among rolled fingerprint frames that are sequentially acquired, calculates the central locations of fingerprints included in the rolled fingerprint frames, sets an order in which the reference frame and rolled fingerprint frames are performed based on the central locations of the fingerprints, and registers and synthesizes the reference frame with the rolled fingerprint frames according to the set order. | 11-24-2011 |
| 20110286640 | ROLLED FINGERPRINT ACQUISITION APPARATUS AND METHOD FOR AUTOMATICALLY DETECTING START AND END OF REGISTRATION AND SYNTHESIS - Provided are a rolled fingerprint acquisition apparatus and method for automatically detecting the start and end of registration and synthesis to acquire an accurate fingerprint. The rolled fingerprint acquisition apparatus compares at least one of fingerprint characteristic information and the amount of variation between the fingerprint characteristic information to reference fingerprint characteristic information to determine whether to start or end registration and synthesis, wherein the fingerprint characteristic information is information about fingerprints included in rolled fingerprint frames that are sequentially acquired, and registers and synthesizes the rolled fingerprint frames according to the result of the determination. | 11-24-2011 |
