Does anyone know about biometrics programming using VB6?

I've read articles about biometrics programming but none of them refers to visual basic. If anyone here knows about this topic, your help would be greatly appreciated. thanks.

What do you mean specifically: biometrics usually involves specific hardware, and usually any decent language (inc VB) is up to it. Specifically though, processor intensive operations such as pattern matching using neural nets (e.g. fingerprint recognition) can only be realistically programmed in assembly or C.

I see what you mean. I have heard about DigitalPersona fingerprint sensor. This can be manipulated using VB6. Do you have an idea about this? Thanks for replying to my thread. Your info is appreciated.

Sorry, is this a piece of hardware or an SDK? If it's the first, you'll need to do the actual pattern recognition using a faster language such as C, i.e. download an open-source library (DLL) and compile it - If you're a genius then write it yourself, but neural nets and AI are the subjects of a PhD thesis, and certainly way beyond me!

Either way, once you've got a library or similar that you know works, you would call it either through the API or a COM reference: the library's documentation should provide the correct declarations/classes to use, and it's basically down to further experimentation.

"is this a piece of hardware of an SDK?"

Well i really don't know. I guess, and i think, that it's both hardware and an SDK that can manipulate the hardware---or is there such thing that exists?. I know its a PhD subject(s) but i'm interested in exploring this kind of technology--in VB of course--and i can't write from scratch the actual pattern recognition. Is there such an SDK that can manipulate such hardware(i.e. DigitalPersona fingerprint sensor)? or an open-source library in VB? do you have an idea about this? thanks for your cool info, rory.

It looks like you're going to have a hard time finding anything that'll work from VB that you don't have to pay for: http://sourceforge.net/projects/ffpis/ was all I could find, but it's still at Alpha. There are plenty of BSD modules as well, but getting them to run on windows and furthermore as a VB COM object would be very difficult - just keep googling, and you'll probably find something!

I'm already having a hard time finding infos on this tech. I'm interested in learning this tech in general and not just focus on a particular brand (i.e. hardware and its SDKs). The site you gave me is cool - first time i've known sourceforge - there fingerprint imaging software sure is interesting. Like you said - just keep googling - hope i can find one. thanks a lot rory

OK, no probs. Good luck with your project .
