I am developing a project in C#, for which I want to login/authenticate a user using their fingerprint. I bought a ZK4500 Fingerprint scanner and got its SDK from http://www.zkteco.com/product/ZK4500_238.html . The SDK is in C++. So How can I integrate this SDK with my C# project to perform the desired functionality? You need to add reference to ZKFPEngXControl that will appear under COM Type Libraries. After that you can use the ZKFPEngX Class to do whatever you require. using ZKFPEngXControl; and then ZKFPEngX fp = new ZKFPEngX(); fp.SensorIndex = 0; fp.InitEngine(); // Do validation as well

Similar to fingerprint authentication for apps, i am trying to implement face recognition authentication in one of my android app. Can anyone guide me on how to achieve the same using any library or anything. Android’s Face Recognition (Software) is less safe than Apple Face ID (Hardware) Because of It doesn’t work in poor lighting conditions It is possible to unlock a phone with a picture So, it’s more a convenience as a feature than a security . I think you should go for Android Face Detection API / Vision API check for the documentation & tutorial find the same on GitHub There is also an

I am using iso 19794-2 fingerprint data format. All the data are in the iso 19794-2 format. I have more than hundred thousand fingerprints. I wish to make efficient search to identify the match. Is it possible to construct a binary tree like structure to perform an efficient(fastest) search for match? or suggest me a better way to find the match. and also suggest me an open source api for java to do fingerprint matching. Help me. Thanks. Do you have a background in fingerprint matching? It is not a simple problem and you'll need a bit of theory to tackle such a problem. Have a look at this

I'm trying to compile the NIST Biometric Image Software, and I have been having trouble all day. I finally got the source checked out right, and I installed cygwin with no problems (I have used it in the past), but when I went to compile, I get this error: $ sh setup.sh </cygdrive/c/NBIS> [--without-X11] setup.sh: line 94: syntax error near unexpected token `$'in\r'' 'etup.sh: line 94: ` case $1 in Now I'm sure any advanced coder would head to the setup.sh and look for problems, but I'm not really much of a coder (I'm only compiling this because there are no pre-compiled packages) so I don't

I've been reading about the subject but cannot get the idea in "plain English" about the usage and parameters for HoughCircles (specially the ones after CV_HOUGH_GRADIENT ). What's an accumulator threshold? Are 100 "votes" a right value? I could find and "mask" the pupil, and worked my way through the Canny function, but I'm struggling beyond that and my problem is the HoughCircles function. There seems to be failing at finding the Iris' circle and I don't know why. And this is the function I'm working on: def getRadius(area): r = 1.0 r = math.sqrt(area/3.14) return (r) def getIris(frame):

How to detect if the user add new fingerprint to Android settings after he/she authenticate finger inside my application ? i.e. iOS have something called (evaluatedPolicyDomainState) to detect changes in fingerprint catalog what is the alternative in Android ? This require for security reasons to prompt password in this case From the documentation for setUserAuthenticationRequired : The key will become irreversibly invalidated once the secure lock screen is disabled (reconfigured to None, Swipe or other mode which does not authenticate the user) or when the secure lock screen is forcibly reset
