摘要:
The present invention relates to a biometrics system and a biometrics method capable of recognizing a user by acquiring geometric features of a finger and a finger joint and then using relative ratio thereof. Because information about relative size or ratio about the finger or the finger joint can be stored, data capacity can be reduced and algorithm can be simple and recognition rate of the system can be increased. The recognition rate can be improved under the state that the amount of information does not increase much compared to a biometrics method using absolute features information only. The system can be composed at low costs compared to the conventional method because a factor increasing the system costs is not added.

摘要:
When a human sensor detects a person to be authenticated, an illumination unit acquires environmental illumination intensity measured by an illumination intensity sensor, determines illumination intensity by using illumination intensity conversion information that is information representing illumination intensity according to environmental illumination intensity, and controls illumination intensity of a light source so that it emits light with the determined illumination intensity. In the above, the illumination intensity according to the environmental illumination intensity is determined such that, when the environmental illumination intensity is low, the illumination intensity is low and such that, when the environmental light intensity is high, the illumination intensity is high. A face authentication terminal authenticates the person with illumination made by the illumination unit.

PURPOSE: A fingerprint reading device and a method thereof prevent contamination due to foreign substances and are resistant against external electronic shocks as the device reads a fingerprint based on a user's capacitance measured in a noncontact manner. CONSTITUTION: When a touch of a fingerprint is sensed, a fingerprint input unit (10) generates a fingerprint image based on the sensed fingerprint. A capacitance measuring unit (12) measures the capacitance taking place by the sensed fingerprint. A fingerprint verifying unit (14) expects the fingerprint image's capacitance and compares the capacitance estimate with the measured capacitance in order to verify the fingerprint. The capacitance measuring unit is installed either in the inside or the outside of the fingerprint input unit and senses changes in the capacitance due to the fingerprint contacted to the fingerprint input unit.

摘要:
Components, methods, and apparatuses are provided for determining activity likelihood function values for an activity classification for two or more past epochs based, at least in part, on signals from one or more sensors of a mobile device. A method may comprise, for each of a plurality of activity classifications, determining activity likelihood function values for each of the plurality of activity classifications for two or more past epochs. The activity likelihood function values may be based on signals from one or more sensors of a mobile device. The method may also include combining the activity likelihood function values to determine a likelihood function for an activity classification at a present epoch. The method may also include inferring a present activity of a user co-located with the mobile device to be one of the activity classifications based on the determined likelihood functions for the activity classifications at the present epoch.

PURPOSE: An optical reading analysis and a voting machine of an RFID(Radio Frequency IDentification) voting verifying system are provided to supply rapid voting result information to a voter. CONSTITUTION: A voting machine(200) is connected to a security voting server within a polling place. A voter enters RFID tag voting paper. The voting machine detects barcode information by voting paper. The voting machine transmits the detected information to the security voting server. The security voting server classifies and records voting information by voting paper. An RFID writer within the voting machine records a barcode number within an RFID tag.
