Is there any biometric data that has a static hash?

Question

Hashing

You need an authentication system. I'm not going to store biometric data myself. Only hash. So it should always be the same. The slightest inaccuracy and the hash is different. I think some features * can be rounded and brought to standards (Separation and rounding of biometric data separately). That is, there are many standards for traits * of biometric information, and each part is checked against all the standards and the most similar one is selected. Everything is collected and hashed. The hash is then sent to the server and checked against the server hash.
*Features of biometric information are:
- for the face - separately the shape of the chin, separately the shape of the oval of the face, separately the shape of the nose, separately the shape of the eyes;
- for voice - frequency separately, timbre separately, intonation separately (I don't understand sound waves);
- for a fingerprint and various information about the eyes, I can’t say anything - I don’t understand.
And one more thing:
To avoid false positives, biometric information is not a login and password, but only a password (that is, it is not a biometric identification system, but a biometric authorization system). Therefore, the login is entered manually by the user.
Actually questions:
Will this technology work?
What biometric data is better to use (restriction - this data must be obtained at home, for example using a webcam or microphone)?
In general, how to make such an authorization so that the hash is always the same, so that the user does not have to bother poking his fingers on the keyboard, but so that this can be done at home and only if the user himself wants it?

Answer 1

By definition, biometric data is mutable.
You can get some staticness only by coarsening them before hashing, and then without any special guarantees. Especially considering the alleged methods of their collection.
