'Anonymized Data' Is A Gibberish Term, And Rampant Location Data Sales Is Still A Problem

The article critiques the pervasive myth that data is truly anonymous simply because personal identifiers have been stripped away. Research consistently demonstrates that location data can be easily re-identified by correlating it with other available datasets. Consequently, the assertion that such information is safe to share is dangerously misleading, as it provides insufficient protection against the re-identification of individuals despite widespread corporate and governmental claims to the contrary. This issue is particularly critical for open data initiatives because it highlights the severe risks associated with releasing user location traces. Even without explicit names or social security numbers, patterns of movement reveal intimate details about a person’s life, including their home, workplace, and daily habits. The opacity of the data brokerage industry exacerbates this problem, as consumers lack visibility into how their information is collected, traded, and aggregated, creating an environment where privacy violations occur without accountability or meaningful user control. Regulatory efforts to curb these practices have largely failed due to powerful industry lobbying and legislative gridlock. As a result, companies continue to collect and sell location data under the false pretense of anonymity, leading to ongoing scandals and breaches. This dynamic is highly relevant to open data because it serves as a cautionary tale: without rigorous anonymization standards and transparent governance, open datasets can inadvertently expose sensitive personal information, undermining public trust and individual privacy rights.
