Hey there! Starting this February, Google rolled out a controversial update that allows advertisers to track users using Device Fingerprinting. Unlike traditional cookies, this method gathers various details from your browser and device to create a distinct digital fingerprint. In this post, we’ll dive into what device fingerprinting is, explore the compliance challenges it poses, and share practical tips for auditing and securing your website.
What Exactly Is Device Fingerprinting?
Device fingerprinting is a tracking technique that collects multiple data points from a user’s device. These can include things like the operating system, browser type, installed fonts, plugins, screen resolution, and more. By blending these factors, a one-of-a-kind digital identifier is formed for each user.
Think of it as walking into a room where people can recognize you based on your appearance and mannerisms, even without you saying a word. Unlike cookies, which need user consent and can be managed or deleted, device fingerprinting operates in the background and isn’t easily controlled by the user.
Why Device Fingerprinting Raises Concerns
There are several reasons why device fingerprinting sparks serious privacy concerns:
- Lack of User Control: Cookies allow users to choose whether to accept tracking or not. Device fingerprinting, on the other hand, functions without explicit user consent, leading to tracking without the user’s knowledge.
- Difficult to Detect: Unlike cookies visible in browser settings, device fingerprinting happens silently in the background. Spotting this type of tracking requires specialized tools and technical expertise not readily available to most users.
- Persistent Tracking: Even if users clear cookies or browser data, the digital fingerprint remains unchanged, enabling continuous tracking despite privacy protection efforts.
- Regulatory Concerns: Privacy watchdogs, like the UK’s Information Commissioner’s Office (ICO), have sounded alarms about tracking methods that bypass user consent. Deploying device fingerprinting without proper consent can lead to regulatory action under laws like GDPR and CPRA/CCPA.
Steps for Privacy Professionals to Address Risks
For privacy professionals, managing the risks associated with device fingerprinting is crucial. Here are some actionable steps to help mitigate these risks:
- Audit Your Website: Start with a thorough audit to identify any device fingerprinting techniques in use. Review both first-party scripts and third-party tools to grasp how data is being collected.
- Collaborate with Your Teams: Partner with IT, marketing, and legal teams to assess the necessity of these tracking methods. Explore if more compliant alternatives can be adopted.
- Limit Data Collection: If device fingerprinting is essential, minimize the collected characteristics and ensure data points aren’t shared with third parties without proper consent. Reducing data points can lower privacy risks and enhance compliance with regulations.
- Vet Third-Party Vendors: Many websites rely on third-party tools for analytics, advertising, and other services. Evaluate these vendors for aggressive fingerprinting practices. If a vendor poses a higher risk, consider adjusting settings or opting for a more privacy-compliant alternative.
- Transparent Disclosure: Update your privacy policy to clearly disclose the use of device fingerprinting. Transparency with users builds trust and ensures legal obligations regarding data collection are met.
- Implement Continuous Monitoring: Websites are dynamic, with scripts and settings frequently changing. Establish a system for regular site monitoring to detect any new or modified fingerprinting practices and track data flows based on consent. Regular audits, be it weekly or monthly, can keep you ahead of potential compliance issues.
