检索指纹数据? [英] Retrieving Fingerprint data?

问题描述

我正在寻找要发送到服务器后端的指纹数据.我的应用程序供销售团队使用，只要有新客户，销售人员就会要求客户扫描其指纹(并最终将其发送到公司服务器).

I am looking for retrieving Fingerprint data to be sent to server backend. My application is used by sales team and whenever there is new customer, the sales will ask customer to scan his fingerprint (and eventually send them to corporate server).

是否可以使用现有的最新API/SDK来做到这一点?

Is it possible to do it using latest API/SDK available out there?

AFAIK，Samsung SDK不提供，Android Marhsmallow也没有.

AFAIK, Samsung SDK doesn't provide it, nor Android Marhsmallow.

推荐答案

API都无法访问指纹图像及其功能.从Android 网站我引用:

Neither, the fingerprint image nor its features are accessible by the API. From Android website I quote:

因此，不得在未经信任的内存中传递原始图像和经过处理的指纹功能.所有这些生物统计数据都需要在传感器硬件或受信任的内存中进行保护. (TEE内部的内存被认为是受信任的内存； TEE外部的内存被认为是不受信任的.)

Thus, raw images and processed fingerprint features must not be passed in untrusted memory. All such biometric data needs to be secured within sensor hardware or trusted memory. (Memory inside the TEE is considered as trusted memory; memory outside the TEE is considered untrusted.)
