Why Your Personal Data Is Worthless: The Dark Reality of Big Data Privacy Leaks

Imagined big data promises streamlined services, but reality reveals pervasive privacy breaches and data exploitation.

As Baidu CEO Li Yanhong once said, Chinese users trade privacy for convenience, showing a cultural openness to data collection.

Recent scandals, such as the mass leakage of celebrity health‑app photos, demonstrate how personal identifiers are harvested and sold, with prices dropping to mere yuan per record.

Numerous popular apps—including TikTok, WeChat Reading, and others—have been officially listed by the Ministry of Industry and Information Technology for infringing user rights, often illegally accessing contacts, location, and other sensitive data.

Legal frameworks like the Cybersecurity Law impose fines that are negligible compared to the profits of companies handling billions of user records, making the cost of crime extremely low.

Consequently, both high‑profile individuals and ordinary citizens become vulnerable, their data exposed and monetized without effective safeguards.

To restore trust in data‑driven services, stronger protection mechanisms and stricter enforcement are essential, yet current measures remain insufficient.

Without meaningful change, everyone risks becoming a "naked runner" in the digital age.
