fingerprint sensor

[Romaxx]

Hi guys,

I am wondering, if you thought about getting access to the finger print sensor data?

Do you thought about this?

Thanks,

Romaxx

Hm… do you have a certain application on your mind? Please note that raw fingerprint data is definitely not accessible…

No, not yet.

I was wondering, if fingerprint sensor data can be accessed some how easily like the acceleration data from the acceleration sensor.

I do not know how such sensor data would look like but phyphox is a app giving access to several sensors and their data, so I thought, you might thought about this?

Thanks.

No, it can't – for good reasons…

Can you elaborate on these reasons?

Security and privacy. The sensor is closely bound to the Secure Enclave and Android's equivalent, respectively, so it is heavily protected by software or even hardware.

What security risk can exist, when raw fingerprint sensor data is applicable? I mean, the sensor has to be faked, not the data, which it produces. Or is it even the functioning principle of the sensor, which would be identified? Would that mean, fingerprint sensors are used to hide their functioning principle in general? But if so, how they can report the fulfillment of specific requirements, like necessary standards? Thanks.

I am not an expert on this, so please check with those who have written https://source.android.com/security/biometric, for instance…
