Device Fingerprint Tracking
Device fingerprint tracking, also referred to as Cross-Channel Tracking, is the tracking of digital traces of a user in the network across different channels.
Instead of using Cookies to track users, device fingerprint tracking uses the technical features, settings and installed software to create a “fingerprint” and track users across multiple channels.
Using this data, a profile or “fingerprint” can be generated which identifies a user in order, for example, to implement a strategy for Content Personalization across multiple platforms.
