Technical requirements
Verifying a person requires that the person concerned is first registered as XY in the recognition system and that a set of data which contains biometric characteristics is stored.

Therefore every biometric verification begins with registration.
  • Choosing a PIN
  • Presenting the finger
  • Calculating the finger pattern
  • Presenting the finger a second time
  • Test

Now it has to be determined whether the person claiming to be person XY has the same characteristics. This comparison requires:
  • Input of identity the person has claimed
  • Recall of the registered person's data from the memory
  • Measurement of biometric characteristics
  • Comparison of measured characteristics with the stored data
  • Display or use of results
