Hi, I'm making a Java Applet that uses GrFinger to authenticate users, but I'm getting an "Unknown error" when using the MatchingContext.verify:
Quote:
com.griaule.grfingerjava.GrFingerJavaException: Unknown error
at com.griaule.grfingerjava.MatchingContext.verify(MatchingContext.java:195)
at com.cinq.afis.Compare.CompareManager.compare(CompareManager.java:84)
at com.cinq.afis.Compare.CompareManager.onImageAcquired(CompareManager.java:70)
at com.griaule.grfingerjava.GrFingerJavaNative.callbackImage(GrFingerJavaNative.java:148)
the code I'm using is:
public void onImageAcquired(String idSensor, FingerprintImage img){
try{
Finger = Matcher.extract(img);
Template bdFinger = new Template();
bdFinger = getData();
compare(Finger,bdFinger);
}catch(Exception e){
e.printStackTrace();
}
}
private void compare(Template a, Template b){
try{
if (a != null && b != null){
if (Matcher.verify(a,b)){
ui.setState("autenticação ok!");
}else{
ui.setState("impressoes diferentes!");
}
}else{
ui.setState("erro!");
}
}catch(Exception e){
e.printStackTrace();
}
}
Does anyone knows what's the problem here?
Thanks in advance.
