Marketers reselling personal information from smartphone apps are working with a massive market of often-unaware users. For instance, as of December 2010, an average of 300,000 Android phones were activated daily.
Although exact figures are not available, advertising and marketing resales have become one of the largest app revenue streams for developers, with a steady stream of financial incentives existing to encourage the sale of information.
The executive branch now appears to be getting involved. In late December 2010, the Department of Commerce announced their intent to overhaul data privacy laws -- which will include smartphones -- following queries by lobbyists and interest groups. A recently released 88-page report from the department calls for the creation of a national Privacy Police Office and demands that companies, either through legislation or self-regulation, ask for customers' permission to collect data from them for marketing purposes. The largest current set of laws relating to online privacy, the Electronic Communications Privacy Act, was originally written in 1986 and has large gaps in coverage of web-era and post-web technologies.
Data mining from smartphone apps is endemic: A recent investigative piece in the Wall Street Journal discovered sensitive personal information was being sent to marketers by popular applications such as Angry Birds, Pandora and Yelp. This information often includes users' contacts, geographical location and a mobile phone ID unique to each user.
One industry group plans a self-monitoring scheme. According to Greg Stuart of the Mobile Marketing Association, "The industry recognizes that in order for marketers and publishers to responsibly and sustainably engage consumers through and with the mobile channel, we need to continuously update how we address the collection, management and use of personal data or related consumer information."
However, the Electronic Frontier Foundation sees a more systemic challenge facing customers from smartphone app marketing. The EFF's Chris Palmer told Talking Points Memo that he is "worried about the weird economic incentives that make this kind of tracking necessary," and referred to the resale of personal customer information by smartphone app developers as "frankly predatory marketing."
