(Updates with Path apology in fourth paragraph.)
Feb. 15 (Bloomberg) -- Apple Inc. tightened its rules over software that accesses address-book information, following a controversy over social-networking applications such as Path uploading users’ contacts data without permission.
Apple is changing its policy to require app makers to get users’ approval before uploading data from their address books, said Tom Neumayr, a spokesman for Apple. Applications that upload contact-list information will need to be updated to meet the new requirements or be removed from Apple’s App Store.
“Apps that collect or transmit a user’s contact data without their prior permission are in violation of our guidelines,” Neumayr said. “As we have done with location services, any app wishing to access contact data will require explicit user approval in a future software release.”
The change follows criticism of the social-networking application Path, which was discovered to be uploading and storing users’ address-book information. Path Chief Executive Officer Dave Morin apologized to users last week for accessing their contacts without permission and vowed to delete all the data.
Accessing address data has become a widespread, little- known practice among many developers for the iPhone, said Alex Stamos, vice president of ISec Partners, a security consulting firm with offices in San Francisco, Seattle and New York.
“It’s extremely common,” Stamos said.
The approach is often used to see if other people in someone’s address book are also using the same app. Users don’t realize it’s happening because they aren’t asked before the information is taken, Stamos said. That contrasts with the policy for accessing location data, which requires people to give permission before the information is made available.
In addition to Path, applications that have been accessing address-book information include Facebook, Twitter, Instagram, Foursquare, Foodspotting, Yelp and Gowalla, according to a VentureBeat report yesterday.
Accessing the address-book information is drawing scrutiny in Washington, where two lawmakers submitted questions to Apple about the practice today. The matter gained attention when a developer, Arun Thampi, wrote in a blog post that he had discovered Path was accessing and collecting the contents of his iPhone address book without his consent.
“This incident raises questions about whether Apple’s iOS app developer policies and practices may fall short when it comes to protecting the information of iPhone users and their contacts,” U.S. House representatives Henry A. Waxman and G.K. Butterfield said in a letter to Apple Chief Executive Officer Tim Cook.
Apple faced questions from lawmakers last year about how user location data was been accessed and stored. Along with other companies, Apple testified before House and Senate committees to defend their privacy practices.
