fingerprint

问题 Has anyone implement fingerprint recognition system in Java? 回答1: For example this comes with java api for linux and windows platforms: http://www.griaulebiometrics.com/page/en-us/manual/fingerprint-sdk-java If you are interested about fingerprint recognition as such, then this book is helpful: http://bias.csr.unibo.it/maltoni/handbook/ For a fast overview, check http://www.cse.unr.edu/~bebis/CS790Q/Lect/BK2_Chapters_1_2.ppt 回答2: Take a look to this open source lib which is well maintained:

问题 I want to make a c++ install deployed windows application that would check hardware fingerprint (to verify that the user will use the application only on his computer). After some net research I decided that WMI is my tool. I started with a simple MFC application and for start I wanted to print out the MotherBoard SerialNumber. And just at this point the whole thing crashed. I checked on XP and Win7 and this property is not returned. And this got me thinking - what if there are some classes

问题 When I create a new Amazon EC2 server, I connect to it using ssh as usual. I see the typical warning: $ ssh myserver The authenticity of host 'ec2-12-34-567-890.compute-1.amazonaws.com (12.34.567.890)' can't be established. ECDSA key fingerprint is 31:66:15:d2:19:41:2b:09:8a:8f:9f:bd:de:c6:ff:07. Are you sure you want to continue connecting (yes/no)? How do I verify the fingerprint before I sign in? Ideally an answer is based on something besides the original creation console log -- because

问题 We are designing a solution that will be used on an internal network. One of the requirements is to have an extra level of security beyond a simple user name and password. Does anyone have information about how to implement a finger print reader in a .net application? We have Thinkpads with a finger print reader. 回答1: you need an sdk (software development kit) to go with your hardware. Add that to your project references and you can communicate with the device. It has to come from the

问题 Is it doable to collect user fingerprint with android? Our backend system has a fingerprint database. We'd like to match the fingerprints collected against database to see if there is a match. 回答1: If by "collect user fingerprint" you mean getting an image of the fingerprint in some form, then no, you can't. Android's fingerprint API essentially works like this: The user enrolls a fingerprint in the Android Settings app. Your app creates a cryptographic key that it associates with the user,

Closed 2 years ago . 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

问题 Is there an efficient way to get a fingerprint of an image for duplicate detection? That is, given an image file, say a jpg or png, I'd like to be able to quickly calculate a value that identifies the image content and is fairly resilient to other aspects of the image (eg. the image metadata) changing. If it deals with resizing that's even better. [Update] Regarding the meta-data in jpg files, does anyone know if it's stored in a specific part of the file? I'm looking for an easy way to

问题 As mentioned here. I'm trying to trigger KeyPermanentlyInvalidatedException when new finger print was added to the device but this exception was not triggering. MyCode FingerprintActivity.java import android.Manifest; import android.annotation.TargetApi; import android.app.KeyguardManager; import android.content.pm.PackageManager; import android.hardware.fingerprint.FingerprintManager; import android.os.Build; import android.security.keystore.KeyGenParameterSpec; import android.security

问题 We are creating a timestamp application on Android and ideally this would use fingerprint to identify the user. In one organisation there can be like 150 different users. Would the fingerprint API allow multiple users? Or is this currently only for the owner of the device? If this is only for the current users, are there any other API's available that would allow this? If not I think we need to abandon this road completely. 回答1: Android M or Samsung or iPhone APIs only allow to verify current

I would like to build an app which allows employees to scan fingerprint with the support of Android app. Right now most fingerprint API (Touch ID or Android Imprint) only allows login to app. Is there any 3rd party API that allows usage of API to collect fingerprint and attach to my employee record, and verify
