SecureUDID - A UDID solution that is secure

SecureUDID is an open-source sandboxed UDID solution aimed at solving the main privacy issues that caused Apple to deprecate UDIDs. Developers can still differentiate between devices as if they were still using a UDID, but only within apps they control. End-users can globally opt-out of SecureUDID collection across all applications and services that use it.
