Dear customer,

Do you want to run through all your database searching for the proper person or do you have a pre-identification method, that finds the person and then you want just to confirm it?
If you're going to use the first method then, the best option is to use the identification method with a loop.
Otherwise, you can select the person in the database and then use the verification method.

This way your identification/verification process will have the best performance.

I hope this is helpful.
Best regards,

I want to run through the database searching for the proper person and I am also using the identification method with a loop. My question is if

I have 1,000,000 records (One million records) or more and the fingerprint of the person i am searching for is at position 999,999 (nine hundred and ninty nine thousand,nine hundred and ninty nine)..

1. Looping will be slow as searching will be done each record one after the other, so what is the fasttest way of identifying such person

2. On a network, dont you think this identification method with a loop process of searching for record will slow down the system or network performace.

Dear customer,

Answering your questions:

1 -If you have more than one core you can divide the search into threads, with a stop flag, also we recomend that all templates are loaded on the memory before the identification itself, loading one per time can consume much more time.

2 - To identify our SDK uses as much memory as possible to make it faster so the system will slow down a little. As for the network, no diference shopuld be noticed unless you send data via network.
