Apple Responds to UDID Leak, Says Did Not Provide Data to FBI
“The FBI has not requested this information from Apple, nor have we provided it to the FBI or any organization. Additionally, with iOS 6 we introduced a new set of APIs meant to replace the use of the UDID and will soon be banning the use of UDID,” Apple spokesperson Natalie Kerris told AllThingsD.With the AntiSec hackers claiming to be in possession of 12 million UDIDs as well as additional personal information tied to some of the numbers, it remains unclear exactly where the data came from.
Apple has been working to phase out use of the UDID, creating new tools to allow developers to track usage of their apps on a per-device basis. With the UDID being a universal identifier, it has been used by advertisers and others to collect information across apps and other usage to develop user profiles for marketing persons, and Apple's new system will seek to improve user privacy.
