Introduction

Canvas fingerprinting is a powerful technique for detecting fraudsters and bots. This presentation explores how attackers modify canvas fingerprints to evade detection and the methods we can use to identify these manipulations.

Canvas fingerprinting uses the HTML canvas API to draw invisible shapes and text that create unique identifiers based on your:

  • Browser

  • Operating system

  • GPU

  • Installed fonts

These fingerprints are stable and unique, making them valuable for tracking fraudsters even if they delete cookies.
