Device and method for biometric verification and registration of a persons identity by means of fingerprint information
First Claim
1. A device for biometric verification of an individual'"'"'s identity using fingerprint information, comprising:
- a controller,a memory,electronic circuitry configured to;
consecutively read and store in said memory fingerprint information from partial areas of a finger,extract and store in said memory verification data from fingerprint information read from a partial area,perform verification processing of the extracted verification data, anddecide if fingerprint information from a new partial area has been read,wherein the controller is configured to use at least those points in time when fingerprint information from a new partial area has been read to update the contents of the memory including removing from memory fingerprint information from previously read-partial areas, andwherein the controller is configured to update the stored verification data on or before said points in time.

Abstract
The invention relates to a device for biometric verification of an individual'"'"'s identity by means of fingerprint information, comprising controller and memory means, means for consecutively reading, and storing in said memory means, fingerprint information from partial areas of a finger, and means for extracting, and storing in said memory means, verification data from fingerprint information read from a partial area, moreover comprising means for verification processing of the extracted verification data, the device also comprising decision-making means for deciding if fingerprint information from a new partial area has been read. At least those points in time when fingerprint information from a new partial area has been read are used by the controller means to update the contents of the memory means, said updating comprising removing fingerprint information from previously read partial areas, the controller means also updating the stored verification data on or before said points in time.
