Dear customer,

When you capture the fingerprint you should extract it and compare with the ones that are already in the database. You can call the identify method over the database.

Then, you will check if it's already enrolled and if not, you can save the new user.

Best regards,

Hi,

 

What i am trying to present is:

 

1. Fingerprint are Enrolled and Stored in database Server at two different locations/sites (Server A and Server B)

 

2. The two servers are brought to the same location for consolidation and Matching

 

3. Fingerprint Stored in Server A should be compared with Fingerpint Stored in Server B

 

4. During the course of comparing the fingerprint stored on the two servers, all fingerprint similarities should be identified and stored in another location before they are deleted 

 

5. Finally, after the comparism is completed, the two database should be consolidated to produce a Single Database.

Dear customer, 

 

May I ask how are the fingerprints stored on the database?

 

The instruction below are valid if the extracted templates were stored instead of the images themselfs:

 

The idea is to remove any duplicates on servers A and B to stored all only once on server C (consolidated).

1 - For each template on server A run an identify loop on server B looking for a duplicate;

2 - Store the template on server C, if there was a match, delete the match on server B.

3 - At the end, server A should be the same as it was when the process started, and server B would have only the templates that weren't present on A. Also, server C is already a copy of server A so all you need to do now is insert all that was left on server B on the new database.

 

Any doubt please contact us.
