使用三星设备的Android指纹扫描

[英]Android Fingerprint Scanning using Samsung device

原文 2015-05-29 12:18:41 1 1 android/ fingerprint

am looking to write an App which will store the fingerprint of the people using it & later use it to authenticate them. 我希望编写一个应用程序，该应用程序可以存储使用该应用程序的人员的指纹，并在以后使用它来对他们进行身份验证。 Now, this App will be placed in a public place, and so there will be thousands of users. 现在，此应用程序将被放置在公共场所，因此将有成千上万的用户。 So, I need to store that many fingerprints. 因此，我需要存储许多指纹。 I tried a simple App with the Samsung PASS SDK , and a Samsung tablet with fingerprint recognition built in. It worked, but looks like it is restricting to three fingerprints only. 我尝试了一个带有Samsung PASS SDK的简单应用程序，以及一个内置了指纹识别功能的Samsung平板电脑。它虽然有效，但看起来只限于三个指纹。 So, a maximum of three fingerprints can be saved & authenticated with, is what I see. 因此，我看到的是最多可以保存和验证三个指纹。 Is this true? 这是真的？ Is it possible to save thousands of fingerprints & use them in the App? 是否可以保存数千个指纹并在应用程序中使用它们？ Or is there any other company (other than Samsung) which offers this capability? 还是有其他公司（三星除外）提供此功能？

AFAIK, this problem is a (totally intentional) limitation from the manufacturer (such as Samsung, Apple...). AFAIK，此问题是制造商（例如Samsung，Apple ...）的（完全故意的）限制。 They have done their job: prevent that biometric data doesn't leave the phone. 他们已经完成了自己的工作：防止生物特征数据不离开手机。 SImple as that. 就那么简单。 I don't know if there is any "illegal" method to retrieve that data to work freely with it. 我不知道是否有任何“非法”方法来检索数据以自由地使用它。

Maybe you can try another approach: A small device with Linux (such a Raspberry Pi if you don't mind the desktop speed) with a USB fingerprint reader attached 也许您可以尝试另一种方法：装有Linux的小型设备（如果您不介意台式机速度，则为Raspberry Pi），并带有USB指纹读取器
