从指纹扫描仪获取指纹模板 [英] Get fingerprint templates from fingerprint scanner
问题描述
我想构建一个生物识别出勤android应用程序.我想获取每个用户的指纹并存储它们并进行相应的匹配.但是我不想使用互联网来存储模板，我想将其存储在sqllite中.如果可以的话，您能告诉我从扫描仪获取指纹的代码吗?
您无法保存指纹图像或模板.它由Android在指纹部分中声明.. >
指纹数据由android系统存储在手机中无法访问的安全位置.您可以编写一个获取并存储指纹以验证用户身份的应用程序.您可以浏览此示例，该示例演示如何使用注册的指纹来验证应用程序中的用户.

如果您需要约300个用户的指纹认证，那么最好的选择是实施 AFIS 解决方案.您也可以查看 github存储库，但我不能保证其准确性.
统计此答案，有些指纹扫描仪与Android平台和Android SDK兼容.这些SDK允许获取指纹图像或模板.扫描仪已插入USB端口，因此您无法同时为平板电脑充电和使用指纹扫描仪.例如:

有些设备还带有集成的指纹扫描仪和SDK，可以获取指纹图像或模板.但这超出了编程的范围.
I want to build an biometric attendance android application. I want to get the fingerprints of each user and store them and match them accordingly. But i don't want to use the internet for storing the templates i want to store it in sqllite is it possible. If possible can u tell me the code to get fingerprint from a scanner
You cannot save a fingerprint image or template. It is stated by Android in the Fingerprint Section.
The Fingerprint data is stored by android system in the phone at a secure location which is not accessible. You can write an app that gets and stores fingerprint to authenticate the user. You can go through this sample that demonstrates to use registered fingerprints to authenticate the user in your app.

If you need fingerprint authentication for about 300 users, your best bet would be implementing an AFIS solutions. You can also check out this github repo, but I cannot guarantee it's veracity.
Stating this answer, there's some fingerprint scanners compatible with Android Platform and with SDK for Android. These SDKs allow to get fingerprint image or template. Scanners are plugged on USB port so you can't charge tablet and use fingerprint scanner simultaneous. For instance:

http://www.futronic-tech.com/product_fs80h.html
http://www.crossmatch.com/authentication-hardware/
There's also some devices with integrated fingerprint scanner and with SDK to get fingerprint image or template. But this would be out of scope for programming.
