The Center for Digital Democracy and the U.S. Public Interest Research Group filed a complaint with the Federal Trade Commission to investigate the growing threat to consumer privacy in the mobile advertising world. Certain services track, analyze, and target the public and build secret profiles. Users are targeted based on their online behavior and their location. The complaint urges the Commission to define and clarify practices, review self-regulation, require notice and disclosure and also protect the public. Earlier, thirty Privacy Coalition members sent a letter to President-elect Barack Obama highlighting the importance of protecting consumer privacy in new network services.
