Fingers enrolled using the R305 module and stored in a database along with the person's name. Next just by typing the persons name, his/her finger template can be stored or deleted in the R305 module ready for authentication.

Template matching problem #5

Open mansoornasir opened 6 years ago

mansoornasir commented 6 years ago

Hi, i have studied your code very thoroughly and found only one problem.

You are comparing templates by downloading it using 'name' from MySQL database before comparison. If i know the name of the person then why would i need a fingerprint reader?

Is there anyway i can compare the hash precisely without knowing the name of the person?

Thank you.

@mansoornasir

In sql, search using finger column then you will get the name of the person

mansoornasir commented 6 years ago

It won't work as every scan is different than other... i mean like more than 80% different.. so 'like' won't work too.

Hello @mansoornasir, I am using your code to save fingerprints from my fingerprint module (R307) to my local database and its all working fine. I am also able to download the hex template file back. But when I try to authenticate, I am unable to do so. If fails the authentication, however if I enroll using the module, it works (it is able to authenticate then). Can you tell me how to get this resolved.

Thanks.

mansoornasir commented 5 years ago

It doesn't authenticate from database, only from flash.

ok, but can i search templates directly from database?? or i need to download it first from database and storage to flash memory position to later search

mansoornasir commented 5 years ago

The problem with this "search" is that it is based on name only, and every time you match the template with database it's different!

So it is kind of useless if you want to search for template. I suggest you use Digital Persona U4U 4500 instead of this R305 module.
