FBI Report) Criminal History Records Information (CHRI) that complies with CJIS Security requirements as well as the highly anticipated FBI Rapback service. Our Central Management Server infrastructure can also securely disseminate FBI Background Check (a.k.a. We engineer advanced software solutions and services that securely and accurately capture, store, and transmit personal information, fingerprints, palm prints, photos, signatures, and DNA. Our online portal offers hundreds of fingerprint locations throughout the United States. Over 3,000 agencies and 6 million applicants around the world have relied on our FBI Certified Live Scan systems for criminal arrests and fingerprint background checks. Biometrics4ALL is an FBI Approved Channeler and our infrastructure has passed the most stringent FBI CJIS Security audits with rare 100% conformance. Our encrypted data security virtually prevents data breaches and reduces cyber security risks. In the second part of this, I’ll describe how I fixed this problem, using the ManualResetEvent object.Biometrics4ALL offers Live Scan fingerprint scanner products and background check services with unparalleled technology, data security, scalability, and flexibility. However, because the fingerprint sample might hadn’t been successfully scanned at that point, I got a null reference exception. So control flows straight on after the call to Enroll to the method which tries to create an image. Scanner.CreateBitmapFile( there was a problem – when designing the implementation, I hadn’t taken account of the fact that the device and SDK is driven by events – so after I start running the program, it’ll happily wait for someone to put their finger on the device screen and won’t block the main thread. using ( var scanner = new DigitalPersonaFingerPrintScanner())

This compiled, and I expected to be able to run the code below.

This seemed pretty straightforward – I wrote the class below.

Stop capturing a fingerprint from the scanner by calling the StopCapture method from the Capture object.

A parameter of the OnComplete handler contains information about the scanned fingerprint.

After the scan has successfully complete, the OnComplete event is fired.

After placing your finger on the reader, the event OnFingerTouch will be fired.

Begin capturing a fingerprint from the scanner by calling the StartCapture method from the Capture object.

Associate an event handler class with this Capture object, which has handlers for the events:.

Add references to the libraries DPFPDevNET.dll and DPFPShrNET.dll, both of which come with the SDK.

So I decided to write a Console application for the U.are.U 4000B scanner.

This SDK comes with a couple of sample Windows applications – but I’ve a personal preference to try to get things to work in a console application, just because it allows me to focus more on the code to get the scanner working (and less on the code to get the Windows app working). NET SDK available, but make sure that when you are buying the scanner device that you get the SDK as well – it’s possible to purchase these separately. To test this, I started looking for other scanners and SDKs – and one candidate which looked very suitable was the digitalPersona U.are.U 4000B sensor. I designed this interface based on the very small amount of knowledge I have of fingerprint scanners and SDKs – so I was still interested to see if this interface would be useful (or even workable) for another scanner and SDK.

I used the Neurotechnology Free Fingerprint Verification SDK with the BioMini hardware.Īs part of the process, I created an interface which allowed me to enroll a fingerprint, and create the image, which defines a good surface for all I want to do at the moment. In a previous post, I used the BioMini fingerprint scanner to generate a bitmap image of a fingerprint.
