C# - 指纹生物识别
我们希望在 .Net 3.5 应用程序中添加对指纹身份验证的支持。
我们目前仅使用 Griaule 的 sdk。但这只支持5个USB即插即用设备。我们希望支持包括笔记本电脑、平板电脑等在内的大多数阅读器。
是否有通用的方法来支持许多设备？我知道从 Windows 7 开始有一个新标准，但我们希望支持 XP 及更高版本。
是否有适用于 UPEK 或 Authentec 设备的 .Net SDK？
任何想法或帮助将不胜感激。
We are wanting to add support for fingerprint authentication in a .Net 3.5 application.
We currently are only using the sdk from Griaule. But this only supports like 5 usb plug-and-play devices. We are wanting to support most readers included with laptops, tablets, etc.
Is there a universal way to support many devices? I know there is a new standard starting with Windows 7, but we want to support XP and higher.
Is there even a .Net SDK out there for UPEK or Authentec devices?
Any ideas or help would be appreciated.

我认为如果您为 WBF 进行开发，如果您希望 UPEK 有一个名为 BSAPI 的 API，您可以在 C# 中进行互操作，那么这是最好的。
I think its best if you develop for WBF, also if you want UPEK has an API called BSAPI that you can interop in C#.
没有通用的方法来支持所有生物识别设备。这是一项相对较新的技术，所有供应商都在争夺市场空间，任何一个都拥有自己的 API/SDK。新的生物识别模式正在开发中，并且与其他生物识别模式没有任何复古兼容性。其中之一是手指和手掌静脉。另一个是多光谱指纹采集，这是一项专利技术。
BioAPI 是一个试图实现通用 API 的倡议，由 BioAPI Consortium 创建。该标准成为 ISO 标准：ISO 19784-2。因此没有最大的生物识别设备供应商的参与。如果您阅读了该规范，您就会发现使用它是多么复杂...
NIST 使用网络服务，任何生物识别设备都将有一个内部网络服务来提供生物识别数据和图像，另一个系统将负责匹配和决策过程。
与此不同的是 Griaule、Neurotechnology 和 Aware 等商业工具，它们试图成为访问生物识别设备的通用方式......
There is no universal way to support all biometric devices. This a relatively new technology and all vendors are fighting for market space any one with their own API/SDK. New modalities of biometric are been developing and no have any retro compatibility with another biometric modalities. One of these is finger and palm vein. Another it is multispectral fingerprint capture that is a patented technology.
An initiative that tried to do that universal API was BioAPI, created by BioAPI Consortium. This standard becomes an ISO standard: ISO 19784-2. Therefore didn`t have participation of biggest vendors of biometric devices. And if you read the specification you will see how complicated is to use it...
Another initiative are been taken by NIST with webservices where any biometric device will have an internal webservice to supply biometric data and images and another system will be in charge of matching and decision process.
Anything different this is commercial tools like Griaule, Neurotechnology and Aware that tries to be a universal way to access biometric devices...
我想说的是，没有这样的用于通用指纹读取的 SDK。
经过一周左右的研究，看起来唯一有希望的是 Windows 7 的 WBF（Windows 生物识别框架）。
这还需要几年的时间才能成为可行的选择。
I am going to say there is no such SDK for universal fingerprint reading.
After a week or so of researching, it looks like the only thing with promise is Windows 7's WBF (Windows Biometric Framework).
It will be a couple of years before this is a viable option.

这家公司提供了一个很棒的 SDK，可以为您提供实际的指纹数据。我不确定它是否仅适用于他们提供的设备，或者是否是其他设备的标准，但是，生物识别技术非常非常好。

This company offers a great SDk that gives you actual fingerprint data. I'm not sure if it's for just the device they offer or if it's standard for other devices, however, there biometrics are very, very nice.
Griaule 支持大量阅读器，包括 UPEK 和 Authentec 阅读器。他们的 SDK 很棒并且使用起来非常简单。您可以在此处查看他们支持的阅读器 http://www.griaulebiometrics.com/page /en-us/fingerprint_sdk/supported_readers
Griaule supports a great number of readers, including UPEK and Authentec readers. Their SDK is great and very simple to use. You can check here the readers they support http://www.griaulebiometrics.com/page/en-us/fingerprint_sdk/supported_readers
