Abstract
Beacon devices may transmit beacon messages to alert an application on a mobile phone of the beacon device's proximity. An encrypted authorization may be used to prevent malicious attacks. Unfortunately, some operating systems, e.g., the iOS™ operating system, strip data fields in service Universally Unique Identifiers (UUIDs) from a received beacon message before the message is passed to the application. Various embodiments provide a protocol wherein the beacon device successively transmits a first beacon message (e.g., an iBeacon™ message) and a second Bluetooth® Low Energy broadcast message. The first beacon message alerts the application of the beacon device's proximity and identity while the second message contains the encrypted authorization and possibly any additional information relevant to the application.
