biometrics

I have a question. I'm making Keystroke dynamics app on android devices. For now, I make an Activity with measure string and EditText . I want to catch KeyDown and KeyUp events on software keyboard. My question is, what is the best way to catch KeyUp and KeyDown on Android with Java? If EditText is a good choice? If it have methods to catch any keypresses? EDIT I want to detect keys from string above and measure time of pressing it, (start measure on KeyDown and stop on KeyUp for example). If its possible, i want to block other keys that is not mentioned in my test string (its 9RJhl6aH0n ,

Is there a way to authenticate to a website using fingerprints? I was thinking of the following scenario. The server has ISO 19794-2 fingerprint templates of all valid users. Client machine has a fingerprint scanner. Client opens website on browser Browser has Java Applet/ActiveX control/HTML5 object gets fingerprint template from the scanner & sends to website. Website allows/disallows based on fingerprint. However, this seems very insecure. It's not difficult to get a jpg of someone elses fingerprint and convert it into ISO 19794-2 template of the same. Then programmatic-ally one can login

Closed. This question is off-topic . It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 4 years ago . i am planning to build a voice authentication system for android devices. Simply meaning instead of the login screen where you have to type your password or draw the pattern, you only only need to say one word such as "Login" and the phone authenticates you and automatically unlocks the phone. I was initially planning to implement it on windows but i am afraid that windows might not support voice bio metrics. So

I'm looking for a totally free fingerprint reader API/SDK that I can use in my Java project. The standard for such things is called BioAPI and you might have luck searching by "bioapi java". Our experience shows that different hardware vendors have their own SDKs and not all of them support BioAPI. 来源： https://stackoverflow.com/questions/6549801/is-there-a-free-fingerprint-reader-api-sdk-for-java

I am working on a fingerprint identification system project,Is there any free sdk available for fingerprint identification system? There are a couple free sdk's that I could find available at: http://www.winsite.com/Development/Components-Libraries/Free-Fingerprint-Verification-SDK/ http://www.neurotechnology.com/free-fingerprint-verification-sdk.html They are both based on Verifinger and have a limitation of storing only 10 records. 来源： https://stackoverflow.com/questions/14133215/is-there-any-free-fingerprint-identification-sdk-available-in-net

This is a very specific question which will probably earn me the tumbleweed badge, but please answer if you can I've imported DigitalPersona sdk dll's as type libraries into Delphi and am trying to verify fingerprints which I've stored as serialized data in a database, it's working very awesomely. Enrollment seems to work fine, but I can't turn the binary data from the finger prints back into DPFPTemplate objects. I keep getting an OLEException every time I try to used the defaultinterface property of a TDPFPTemplate object. What I'm wondering is how Digital Persona expects you to use their

How can I do a basic face alignment on a 2-dimensional image with the assumption that I have the position/coordinates of the mouth and eyes. Is there any algorithm that I could implement to correct the face alignment on images? Face (or image) alignment refers to aligning one image (or face in your case) with respect to another (or a reference image/face). It is also referred to as image registration. You can do that using either appearance ( intensity-based registration ) or key-point locations ( feature-based registration ). The second category stems from image motion models where one image

I have the following values against FAR/FRR. i want to compute EER rates and then plot in matlab. FAR FRR 19.64 20 21.29 18.61 24.92 17.08 19.14 20.28 17.99 21.39 16.83 23.47 15.35 26.39 13.20 29.17 7.92 42.92 3.96 60.56 1.82 84.31 1.65 98.33 26.07 16.39 29.04 13.13 34.49 9.31 40.76 6.81 50.33 5.42 66.83 1.67 82.51 0.28 Is there any matlab function available to do this. can somebody explain this to me. Thanks. Let me try to answer your question 1) For your data EER can be the mean/max/min of [19.64,20] 1.1) The idea of EER is try to measure the system performance against another system (the

I am trying to connect with a Biometric Fingerprint Attendance Device using a Java program. The device I am using is a Biocom Fingerprint attendance system. However, I am search and reading about that and I see the SDK could used which based on device type (which hard, not logical, moreover, it is not global solution!) I research for a global standard on how to connect, send and retrieve data with a Fingerprint Device which again I wasn't lucky enough to find a clear solution. Currently, I tried to connect with the device by creating a Socket object (through Ethernet port) but also not
