Inside the Industry That Unmasks People at Scale
Tech companies have repeatedly reassured the public that trackers used to follow smartphone users through apps are anonymous or at least pseudonymous, not directly identifying the person using the phone. But what they don’t mention is that an entire overlooked industry exists to purposefully and explicitly shatter that anonymity.
They do this by linking mobile advertising IDs (MAIDs) collected by apps to a person’s full name, physical address, and other personal identifiable information (PII). Motherboard confirmed this by posing as a potential customer to a company that offers linking MAIDs to PII.
