Abstract: The present disclosure relates to methods and systems for generation of a beacon identifier (ID) for increased security of a system for a location based service. The system includes a beacon device, such as a BLE device, a mobile device, and a server. The beacon device is configured to generate a beacon ID based on a beacon device identifier, such as a unique device identifier, of a beacon device and a time value. In some implementations, generation of the beacon ID includes a pseudorandom function and a shared key that is established between the beacon device and the server.
