Please note that you will need an active, dynamic and enrolled biometric server profile for the following configurations. For more information about the biometric server please do not hesitate to contact us. Please also note the following preconditions:
Please also note: In order to be able to verify signatures it is necessary to collect six signatures in the biometric server. For more information please have a look at: SIGNificant Biometric Server (restricted access) |
The Story 
In our scenario, we are using the fictitious persona Maria McCartney. Imagine Maria as a 57 years old woman with 2 children, who has worked as employee of a big company until her age of 32 and then, after her maternal leave, spent all her energy on household and caring about her children. She is not using electronic banking and therefore is used to go to the bank once a week to do all the payments for the rent, the electricity and others. She also withdraws the money she needs in cash once a week directly at the cashier's desk.
When opening her bank account back some years, she had to sign several times so that the bank collected a sample of her valid signatures. The bank was already digitalized and collected the reference signatures in the SIGNificant Biometric Server. Whenever Maria is withdrawing money at the cashier's desk, she is signing again electronically on a device such as the Namirial NT10012 where she is able to see the bank statement for the withdrawal. Using her handwritten biometric signature is the most natural way of signing in a face-to-face scenario, and perfect for this scenario. The signature is in real-time, fully automated, verified against the reference signatures stored in SIGNificant Biometric Server to guarantee that it's really Maria who is withdrawing the money and not her sister who looks very similar to her. Every time when she is signing successfully, the signature is expected to vary slightly, but not too much, from the stored reference signatures. As a person's handwritten signature in general typically changes slightly over the years, the stored reference signatures are automatically updated with newer data each time she is signingCharly wants to open a new bank account. In order to be able to guarantee that Charly and no one else signs future signatures, Charly has to sign six times to collect them in order to use those six signature to verify future signatures from Charly. This ensure that even if Charly does not sign directly in the bank, his signatures, which are digitally signed, are verified with the collected six signatures to check if Charly signed the document.

In order to verify the signature with the collected six signature from the enrolled biometric server the following attribute must be set:
