iPhone UDID opt-in for iOS 5

Tuesday, September 20th, 2011

iOS gives consumers the option to allow specific applications to pull geo data from the handset, and utilize this data to improve the application’s performance, utility, and ad targeting. Below is a mock-up that shows how a similar methodology could have been used to give consumers the chance to transmit encrypted device identifiers. This will not happen for UDIDs (that train has left the station), but it seems to me that a similar opt-in procedure will be required to uniquely track and identify mobile users in the future. No matter if the device ID, MAC address, cookies, or fingerprinting  is used.
