Data use and sharing disclosures on mobile devices need work, the FTC said in a staff report released last week.  The report recommends ways that actors in the mobile marketplace—such as mobile operating system providers, application developers, advertising networks, and analytics companies—can inform consumers of data collection and sharing practices.  While the FTC tailors recommendations for each group, the recommendations are essentially focused on providing consumers with timely and understandable data use disclosures.  If such disclosures do not materialize, FTC Chairman Jon Leibowitz said to reporters in a teleconference discussing the report, the mobile industry may face regulatory or legislative mandates.
