From EPIC.org:
EPIC has filed a complaint with the FTC asking the Commission to investigate Google’s tracking of in-store purchases. According to EPIC, Google collects billions of credit and debit card transactions and then links that personal data to the activities of Internet users. Google claims that it protects online privacy but refuses to reveal details of the algorithm that “deidentifies” consumers while tracking their purchases. EPIC’s complaint asks the FTC to stop Google’s tracking of in-store purchases and determine whether Google adequately protects consumer privacy. EPIC has filed several successful FTC complaints that led to FTC investigations, including complaints about changes to Facebook’s privacy preferences and the launch of Google Buzz. EPIC has also focused on the adequacy of privacy techniques, with complaints against AskEraser (search histories that are not deleted) and Snapchat (images that do not “vanish”). EPIC’s recent complaint against Google notes that the company is seeking to extend its dominance of online advertising to the physical world.
