I need urgent help, after googling a lot since last 3-4 weeks. I only able to figure out that, i can use digital persona sdk on my web application, which i am trying to make in java.
Since, hardware for fingerprint reader (Digital Persona Personal) has already been installed in my system. And, i'm trying to use same hardware for my web application. But, how can i embed it in my application, don't know.
I'm assuming that, fingerprint reader (Digital Persona Personal) will be installed in client side.
I need everyone help, anybody know.. i'll appreciate !!
Well, what you want to achieve can be a bit hard to do depending on your needs/experience, but having done a biometric matching/enrollment/digital signature system in delphi(client)/java(server) i can summarize the steps as follows:
1.- The client is an win32 activex (could be a java applet) that can take a fingerprint image and send it to the server for matching or enrollment purposes, the server takes the image and applies a matching function that returns a score, here i recommend you to take a look at some paid options like verifinger, griaule etc. I dont know if it can be done with the UareU One Touch SDK.
2.- The client is an Activex embedded in the web page as an object (calling an applet is very similar), you just call it with a simple javascript code like "identResult = activexObj.Identify()" or something. The image is sent to the server which in return replies if the fingerprint matches the template stored, comparing the score vs threshold defined as the minimum for matching.
3.- Probably you will need to do some image processing in the client, like converting your raw image to a compressed format like WSQ, there are no (to my knowledge) java implementations of wsq, so you will have to interface to native code via JNI for this purpose.
4.- There might be a lot of nuances but i hope this helps you to clarify the situation. Good Luck Juan.
