Over 1,000 children's apps illegally tracking kids: Study

Most of nearly 6,000 children's apps found to be in potential violation of US privacy law

WASHINGTON • Thousands of free, popular children's apps available on the Google Play Store could be violating US child privacy laws, according to a new, large-scale study, highlighting growing criticism of Silicon Valley's data collection efforts.

Seven researchers analysed nearly 6,000 apps for children and found that the majority of them may be in violation of the Children's Online Privacy Protection Act, or Coppa.

Thousands of the tested apps collected the personal data of children under the age of 13 without their parents' permission, the study found.

"This is a market failure," said Dr Serge Egelman, a co-author of the study and the director of usable security and privacy research at the International Computer Science Institute at the University of California, Berkeley.

"The rampant potential violations that we have uncovered point out basic enforcement work that needs to be done."

The potential violations were abundant and came in several forms, according to the study.

More than 1,000 children's apps collected identifying information from children using tracking software whose terms explicitly forbid their use for children's apps, the study found.

The researchers also said that nearly half of the apps fail to always use standard security measures to transmit sensitive data over the Web, suggesting a breach of reasonable data security measures mandated by Coppa.

NEED FOR ENFORCEMENT

This is a market failure. The rampant potential violations we have uncovered point out basic enforcement work that needs to be done.

DR SERGE EGELMAN, a co-author of the study and the director of usable security and privacy research at the International Computer Science Institute at the University of California, Berkeley.

Each of the 5,855 apps under review was installed more than 750,000 times, on average, according to the study.

Unfortunately for parents, there is little consumers can do to protect themselves since the policies and business practices of app developers and ad tracking companies are often opaque, Dr Egelman said.

The study also points to a breakdown of so-called self-regulation by app developers who claim to abide by child privacy laws, as well as by Google, which runs the Android platform, he said.

The apps in question included Disney's Where's My Water?, Gameloft's Minion Rush and language learning app Duolingo.

 

The findings also suggested that app creators that had been certified as Coppa-compliant were no better than any of the other apps at protecting children's privacy.

The researchers used a testing platform that allowed them to see in real time how often the apps accessed sensitive information - such as location data and contact lists - on a phone and what other entities the apps shared that information with.

Disney, Gameloft and Duolingo did not immediately respond to a request for comment.

The researchers noted that Google has worked to enforce Coppa by requiring developers of children's apps to certify that they comply with the law.

"However, as our results show, there appears to not be any (or only limited) enforcement," the researchers said.

They added that it would not be difficult for Google to augment their research to detect the apps and the developers that may be violating child privacy laws.

Google did not respond to a request for comment.

Critics of Google's app platform say that the company and other players in the digital advertising business, such as Facebook, have profited greatly from advances in data tracking technology, even as regulators have failed to keep up with the resulting privacy intrusions.

"Google has basically looked the other way while it was able to generate revenues off of children's apps," said Centre for Digital Democracy executive director Jeffrey Chester.

"The new, alarming report is further evidence that Google is thumbing its nose at the only federal online privacy law that we have."
