ID Visitor & Privacy in Data Management

Context

In the ePrivacy Exemption or hybrid measurement context, the visitor ID property needs to be hidden so that it does not appear in visitor modes other than opt-in.

This hiding makes it possible to maintain the calculation of visitors, without restoring the identifiers.

However, it is permissible to retrieve the visitor ID value when the event's visitor mode has the value opt-in. To meet these expectations, we can use a Data Model property rule.

Prerequisites

Before implementing, it is necessary to validate these 2 questions:

The scope of the ownership rule

Should the rule be applied to the organization, the group of sites or the site?

The rule can be applied to different perimeters.

Tagging in place

Is the perimeter concerned tagged with recent privacy marking methods?

These feed the visitor_privacy_mode parameter required for the rule.

Process

1. Property creation

The property must be of type string and must have the status validated.

2. Rule editing

The property rule must consist of a first condition block with the following configuration:

IF String visitor_id tag parameter is not empty

AND IF Tag parameter visitor_privacy_mode of type string is equal to opt-in

THEN the property is defined by the value of Parameter tag visitor_id of type string

Example :

3. Save

Then click on Save

The rule will take effect within a maximum of 20 minutes.
