在找写一个应用程序将保存用它与放人的指纹;后来用它来验证他们的身份。现在，这个应用程序将被放置在公共场所，所以会有数以千计的用户。所以，我需要存储许多指纹。我想一个简单的应用程序与三星PASS SDK 和三星平板指纹识别内置的。它的工作，但看起来它限制到只有三个指纹。因此，最多三个指纹可以保存和放大器;与验证，是我看到的。这是真的？是否有可能拯救成千上万的指纹和放大器;在App使用它们？或有任何其他公司（三星相比除外）提供此功能？

am looking to write an App which will store the fingerprint of the people using it & later use it to authenticate them. Now, this App will be placed in a public place, and so there will be thousands of users. So, I need to store that many fingerprints. 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. So, a maximum of three fingerprints can be saved & authenticated with, is what I see. Is this true? Is it possible to save thousands of fingerprints & use them in the App? Or is there any other company (other than Samsung) which offers this capability?

推荐答案

据我所知，这个问题是从制造商（如三星，苹果...）一个（完全故意的）限制。他们做他们的工作：prevent的生物特征数据不离开手机。就那么简单。我不知道是否有任何非法的方法来检索数据与它自由地工作。

AFAIK, this problem is a (totally intentional) limitation from the manufacturer (such as Samsung, Apple...). They have done their job: prevent that biometric data doesn't leave the phone. SImple as that. I don't know if there is any "illegal" method to retrieve that data to work freely with it.

也许你可以尝试另一种方法：使用Linux的小型设备（例如一个树莓派，如果你不介意桌面速度）附带一个USB指纹识别器

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
