Hallo,
Ich bin mir nicht ganz sicher, was du mit Fingertracking meinst.um Gesten von Personen im 3d-Raum zu erkennen .
Wenn du das etwas genauer beschreibst, kann ich vielleicht helfen.

Hallo,
Zum Thema fingerprinting ist die Logik hier beschrieben:
https://matomo.org/faq/general/faq_21418/
Kurz gesagt: Wenn Cookies deaktiviert sind, versucht Matomo die Besucher basierend auf anderen Dingen wiederzuerkennen.
Seit 3.13.6 ist das fingerprinting auch etwas limitiert geworden:
matomo-org:3.x-dev ← matomo-org:cookiefingerprint
opened 09:41PM - 29 Apr 20 UTC
The purpose of the fingerprint is to put all tracking requests within the same v… isit into the same visit in the DB. A fingerprint is basically valid for up to 30 minutes after the visit ends (unless different visit length is configured).
By adding a random hash to the fingerprint we make sure when a user disables cookies, a visitor cannot be identified across multiple days and such no cookie consent should be needed.
This change should not really change behaviour for anyone AFAIK. In Matomo 4 we could remove the check for `create_new_visit_after_midnight` potentially. We cannot limit the fingerprint in that case as when someone has `create_new_visit_after_midnight=0` and has cookies disabled, then a new visit would be still created after midnight since the configId would change.
The limited fingerprint will also not apply when enabling `[Tracker]enable_fingerprinting_across_websites = 1` since different sites can have different timezones and therefore we can't add any date to the fingerprint.
