Summary

The text discusses Google’s use of pseudonymisation rather than anonymisation in data handling, highlighting that while Google can anonymise IP addresses, this is not universal and may not occur before transferring data to the USA. It emphasizes that unique identifiers can render data identifiable, especially when combined with other metadata, raising concerns about user tracking. The EDPB recognizes that while pseudonymisation may offer some protection, it requires careful analysis to prevent re-identification. Additionally, the integration of Google Analytics with other services increases tracking risks, allowing cross-referencing of IP addresses and user histories. It distinguishes between pseudonymisation, which replaces identifying data with indirect identifiers, and anonymisation, which irreversibly prevents identification and exempts the data from GDPR regulations.

Signals

name description change 10-year driving-force relevancy
Increased scrutiny on data transfer practices Regulatory bodies show heightened concern about data anonymisation and pseudonymisation. Shift from lenient data transfer practices to stricter scrutiny and regulations. In 10 years, data transfer will be heavily regulated, ensuring higher privacy standards. Growing public demand for data privacy and protection against misuse. 4
Integration of tracking technologies Widespread use of tracking technologies across multiple platforms raises privacy concerns. Transition from isolated data use to interconnected tracking systems that enhance user identification. In 10 years, tracking technologies may be ubiquitous, leading to more personalized but intrusive user experiences. Advancements in technology and marketing strategies that rely on user data. 5
Potential for re-identification Concerns arise about the ability to re-identify individuals from supposedly anonymised data. Move from perceived anonymity in data to potential risks of individual identification. In 10 years, methods to re-identify individuals may become more sophisticated, challenging privacy laws. Technological advancements in data analytics and machine learning. 5
Collaboration between services heightens risks Using multiple Google services together increases the risk of user tracking. From individual service usage to combined data that enhances user tracking capabilities. In 10 years, integrated services may create comprehensive user profiles, making privacy harder to maintain. Business models relying on data integration for improved marketing effectiveness. 4
Emerging legal frameworks for data protection The evolving legal landscape surrounding data protection and privacy rights is becoming more complex. Shift from basic data protection laws to comprehensive frameworks addressing modern data practices. In 10 years, legal frameworks for data protection may become more robust and universally enforced. Increased awareness and advocacy for individual data rights and protections. 3
