Hello there, i'm new to fingerprints systems, i'm developing an authentication system and i would like to add fingerprint authentication using libfprint, but all data would be stored on a database, my authentication system would be distributed among some terminals, and connectivity to the central database probably wont be the best and fastest. So, if possible, I would like to convert fingerprint to a database storable string which could be compared for identification and verification. I saw on the API that exists fp_print_data_get_data which can convert a struct fp_print_data into an array of chars representation, i didnt tested (because of some impossibilities libfprint yet, are these string representations suitable for database storage? and for identification through a database system query like" "select * from user where fingerprint='some-fingerprint-data'"? what size can that string reach ? Sorry by bothering with these kind of questions, if someone could help me i would apreciate it very much! :-)
my best regards, José Trancas
