UUID (Universally Unique Identifier): A sequence of 128 bits that can guarantee uniqueness across space and time, defined by [RFC 4122][rfc4122].

UDID _(Unique Device Identifier)): A sequence of 40 hexadecimal characters that uniquely identify an iOS device (the device's Social Security Number, if you will). This value can be retrieved through iTunes, or found using UIDevice -uniqueIdentifier. Derived from hardware details like MAC address.
