Anonymous reminds Apple that UDIDs are creepy — Apple News, Tips and Reviews.
I am not sure which is more creepy, the way in which Apple has been using Unique Device Identifiers (UDIDs) to track iPhone and iPad users’ behavior or the fact that (if the claims of where these leaked UDIDs came from are true) the fact that an FBI agent had a trove of over 12 Million of them, along with other personally identifiable information matched up to these UDIDs.
In any event, it goes to show that there remain many concerning security and privacy issues surrounding the use of mobile devices.
