Appsfire said the OpenUDID user identification effort is set to take a “radical turn” with the arrival of Apple’s iOS6, but that it cannot detail its plans because “the instigator is bound to the pre-release iOS6 NDA [non-disclosure agreement]”.

OpenUDID was introduced last year, when Apple decided to end support for the use of unique device identifiers (UDID) as a tool to track users – the identifiers are tied to specific handsets, and cannot be removed or modified, creating potential privacy issues.

In a blog post, it noted that at Apple’s Worldwide Developer Conference, “the future of UDID was revealed”, although little was made public. The Wall Street Journal had previously reported that Apple is planning a replacement for UDIDs that are not tied to specific devices.

It also said that while OpenUDID will “at some point” be depreciated as the new tracking technology comes into place, there will be some overlap where iOS5 and iOS6 co-exist – “OpenUDID should remain the go-to solution of “UDID” handling well into 2013… and not just for iOS (ports available for Mac OS X, Android, and others)”, it said.
