We live in the age of big data. The surge of AI has rekindled the debate on data ownership and use, but the problem with data collection online is about far more than training AI with content.
Data is at the core of the success of platforms like Google and Meta, while cybercriminals steal and deal data. In the end, big corporations and criminals alike harvest, and profit from, our data, which is far from harmless. Data is powerful, as even the smallest amount can reveal a lot about us - we are not just talking about personal data, but also about linking information. For example, seemingly anonymized data can easily be linked to identify a person. Almost 90% of people living in the U.S. can be uniquely identified by combining their ZIP code, birth date, and their legal sex, while more than half can be identified by merely knowing their city, birth date, and legal sex.
Even more strikingly, in 2013, researchers built a model that predicted personal traits based on the Facebook likes of a user. The success rate varied between 60 to 90%, predicting traits like whether the user's parents were still together before the user turned 21 or political party affiliation. All of this goes to show that data is sensitive, and even keeping track of simply insignificant data points has the potential to de-anonymize us. Not only is our data at risk, but also our autonomy and freedom.
A straightforward solution to this issue would obviously be the mass exodus from the online world. But refraining from using the internet is almost impossible today. May it be a job hunt, finding an apartment, or accessing governmental services - we are increasingly bound to the digital sphere, whether we like it or not. While data collection, handling, and storage are crucial issues to tackle, it is equally important that users are aware of what happens to their data and what they consent to when they use digital services. Importantly, we are not only limited by the data that is collected now, but also how the data collected today could be used in the future.
At the European level, the General Data Protection Regulation (GDPR) and the ePrivacy regulation were designed to protect and inform users. In reality, the mandatory cookie notifications that pop up on every website one opens have led to consent desensitization, taking away the meaning of consent.
