Apple has already provided a few clues as to what it is going to put on the plate for developers at Worldwide Developers Conference (WWDC).
One change that is unlikely to be touted at the keynote, or even the entire conference, could prove to be the most important for app writers. This change is about an alternative to the Unique Device Identifier (UDID).
Apple started phasing out a year ago. If Wall Street Journal (WSJ) tipsters are to be believed, the hardware-specific ID will be replaced with tagging independent of any one iPad or iPhone, such as a number sequence.
The system as it is teased would let developers track user behavior and improve their apps without spooking users worried that Apple, or someone else, might snoop over their shoulders by linking a UDID to the owner.
This certainly sounds like a remedy to mounting privacy concerns to the users, although an unveiling supposedly due within the “coming weeks” raises the possibility that the new ID would not show its face until after the programming hordes have already left San Francisco.
