Thanks. We'll let you know when a new response is added.

The following might be useful to you:

The <a href=”http://www.soft14.com/nice_or_free_software/bi/biometric-972.html”>GSA image analyzer</a> is a program used to compare images, this might be useful in your application.

<kccrosser> As someone who has worked in the Public Safety area for many years, I have never heard of a successful “image” comparator for fingerprints. Every technique I have seen is based on doing image analysis, extracting “features” and constructing a “minutia” template. Then, comparisons are done by various algorithmic comparisons of the minutia templates (non-trivial in itself).

There are companies that will sell you libraries for feature extraction and minutia matching. You might want to look at the “free” library available in technet at the following link:

Good luck.

    ...all i need is a source code in vb.net ...   The answer above gives some direction on how to locate a company that might sell some libraries to you. But any source code will probably be very expensive. Companies that do this work will not be willing to give their secrets away.   Tom

    If you want to know about the source code, then you need to read what's already in this thread. There is no more to add to the conversation. Tom
