In-app ads allow for free, "lite" versions of many of your favorite apps, but are those ad networks also peeking at your personal information?
A new
report from North Carolina State University researchers found "threats to security and privacy" with the ad libraries used in many popular Android apps.
The researchers, with the university's department of computer science, analyzed 100 ad libraries selected from a sample of 100,000 apps in the Android Market,
now known as Google Play, between March and May 2011.
"Such threats range from collecting unnecessarily intrusive user information to allowing third-party code of unknown provenance to execute within the hosting app," the report found.
The study said that Android's permissions model can't distinguish between actions performed by an ad library and those performed by its hosting app. As a result, "the current Android system provides little indication of the existence of these threats within any given app, which necessitates a change in the way existing ad libraries can be integrated into host apps."
