Wat er gebeurt
Scripts read properties that together make a device distinctive: time zone, screen metrics, fonts, canvas or WebGL rendering, enumerated navigator fields. No cookie is stored, so cookie controls do not touch it.
Waarom het ertoe doet
Recognition without storage escapes exactly the controls people are told to use. Clearing cookies and refusing consent leave the technique untouched.
Veelvoorkomende oorzaken
- anti-fraud or bot-detection library that also serves marketing
- advertising script with built-in fingerprinting
Dit is het níet
Reading a time zone to localise a page is not this entry. The distinguishing feature is enumeration of multiple properties by a third party.
Hoe je het vaststelt
Indicator
Within one page load, a script under a different registrable domain reads three or more distinct classes of device property, of which at least one is a canvas or WebGL rendering, an enumeration of installed fonts, or an enumeration of navigator or media-device fields. A single reading, such as the time zone, does not qualify: it is the combination that makes a device distinctive, and the combination is what the indicator has to show. Record which reads the same script performed, so the count is attributable to one party rather than to the page.

De grenzen van deze bevinding
Wat dit patroon zou weerleggen
- The properties are read by a first-party script, not a third party.machinaal te toetsende bevinding krijgt een ander patroon
- The reads serve a functional purpose such as localisation or accessibility.niet uit de meting af te leidende bevinding wordt zwakkerPurpose cannot be established from a capture. The entry establishes the reading, not the intent.
- The reads come from a component the operator engaged for fraud or bot detection and the result is not used for recognition beyond that purpose.niet uit de meting af te leidende bevinding krijgt een ander patroonThe reading itself still engages the terminal-equipment provision, so this narrows the finding instead of removing it. It is a question for the operator.
Wat dit patroon níet vaststelt
- harm; the catalogue standardises a finding so it can be referred to, it does not weigh it
- severity; there is no score here, by design. Weighing belongs to whoever applies the entry to a concrete case
- unlawfulness; that is for a supervisory authority or a court
- intent; a fault is usually a build decision, not a plan
- absence: not finding it in one capture is not evidence that it is not there
