Each Apple iOS device comes with a completely unique identification number called a UDID. For a while now apps have been accessing and tracking that identifier and now it appears Apple is going to crack down on apps that do so. Access to the UDID is not necessarily a big deal but it does enable advertisers to track users quite a bit better. This is precisely why Apple is cutting out any and all apps that use the UDID as a tracking method.
This is good news for all iOS users because it will increase privacy and reduce advertisers ability to track you. Apple has made it clear for a while that they were planning to do this, but until now they hadn’t made it official. Apple is now telling developers that the time to fix their apps is now because in the coming weeks there will be a final crackdown on applications. The increased privacy is very good for users and this change should also allow developers to find better and more efficient ways to control their apps. No word yet on if any developers are planning to fight this change but at this point it definitely looks like they have no choice. Apple is also planning to make a few more changes in the future regarding privacy through apps but they haven’t announced anything just yet. Either way this is very great news for all iOS users that need a little bit more privacy from the apps they are constantly downloading.
