Google's updated rules permitting online fingerprinting have ignited strong criticism from privacy advocates who argue that the tech giant is prioritizing profits over user privacy. The new measures allow for the collection of more detailed user data, raising alarms about control over personal information.

Google's New Fingerprinting Rules Spark Privacy Backlash
Privacy advocates condemn Google's recent policy change allowing fingerprinting, raising concerns over user protection and data exploitation.
Critics have expressed outrage over Google's recent policy changes regarding online tracking, labeling them as a blatant infringement on user privacy. Set to take effect on Sunday, these modifications allow for "fingerprinting," a data collection method that enables advertisers to seek detailed information about individuals, such as their IP addresses and device specifics.
Google asserts that fingerprinting is a common industry practice and insists that it promotes the responsible use of data. However, it stands in stark contrast to the company’s previous stance; back in 2019, Google publicly condemned fingerprinting as a method that undermines user choice. In a recent blog post outlining the new rules, Google claimed that evolving internet use, especially with devices like smart TVs and consoles, has made conventional cookie-based data collection less effective.
The tech giant further emphasized the implementation of enhanced privacy options to protect its users. "Privacy-enhancing technologies offer novel pathways for our partners to thrive in new platforms without compromising user privacy," a company representative stated.
Despite Google's assurances, opponents argue that the adoption of fingerprinting and IP address tracking infringes on individuals' ability to manage their data collection. Martin Thomson, a distinguished engineer at Mozilla, stated, "By permitting fingerprinting, Google gives itself and the advertising sector it dominates a license for tracking methods that users find difficult to contest."
To clarify, fingerprinting aggregates various bits of a user's device and browser information, crafting a distinct profile of the individual. While some data—like screen size and language—are necessary for functionality, when combined with other variables such as time zone, browser type, and battery level, it culminates in a unique fingerprint that can facilitate targeted advertising.
Before this new rule, Google prohibited the use of both fingerprinting and IP address data for advertisement targeting. Privacy advocates are particularly concerned that fingerprinting lacks user control, unlike cookies that users can manage. "Google's acceptance of these tracking methodologies, previously deemed incompatible with user control, illustrates a clear shift toward prioritizing profits over privacy," remarked Lena Cohen, a staff technologist at the Electronic Frontier Foundation.
The potential implications of this policy shift have raised alarms among industry experts like Pete Wallace from advertising technology firm GumGum. He highlighted that fingerprinting occupies a "grey area" concerning user privacy, questioning whether consumers should feel at ease in such uncertainty.
GumGum's approach revolves around contextual advertising, which utilizes non-personal data like website keywords to target ads, a method that contrasts with Google's new direction. Wallace voiced concern that the move toward fingerprinting signifies a business-driven strategy towards consumer data, diverging from a more consumer-focused approach to privacy.
The advertising sector fundamentally underpins many free online services, necessitating user data for relevant ad placement. However, UK regulators from the Information Commissioner's Office (ICO) have flagged fingerprinting as an unfair tracking practice, limiting user choice and control. In December, ICO Executive Director Stephen Almond remarked that the move seemed "irresponsible" and suggested businesses using such technologies must meticulously comply with data protection laws.
Google, seeking to address the concern, plans to discuss these modifications further with the ICO, emphasizing that data signals like IP addresses have been responsibly managed in its operations for years. A company spokesperson reaffirmed the commitment to user choices in receiving personalized ads and fostering responsible data practices across the industry.
