The good news: it works brilliantly. Minutiae detection and comparison completes instantaneously and the results appear to be accurate and reliable. In other words, if I scan my finger twice it says its the same finger, and if I scan two different fingers it says they are different. I’m now in a position to follow up my larger plans of producing a generic fingerprinting library for a range of hardware, except…
The bad news: I’m not going to distribute any more work on libdpfp until I have found legal advice which tells me it’s OK to do so. I’m now at the position where I have a load of code I can throw at lawyers and say “this is exactly what I want to distribute”, so this is where the hunt begins.
If anyone has suggestions for people I might contact (even non-legal types who might be able to pass me on to someone), or has experience seeking advice in this kind of area, please contact me. I’m aware that such advice will probably cost money, although I don’t have any idea how much. Raising funds to cover costs might be a possibility.
In summary I’m looking for someone who understands (or can figure out how to interpret) US export control laws. I guess I also require a tech type who understands the concepts of software distribution to some degree. Any guidance appreciated!
