A privacy advocacy group has decided to file a formal legal complaint with the US Federal Trade Commission, asking for an investigation into Google’s in-store tracking algorithm to decide whether or not it protects the privacy of American consumers. The system allows the company to extend its online tracking capabilities into the physical world. The idea is to combine credit card and other financial data to create a singular profile to illustrate to companies what goods and services are being searched for online, which result in actual in-person sales.
