You're building a mobile application which tracks people in your proximity, the time in proximity must exceed five minutes to be noted. Tracking requires that the same application is installed, on and also that the Bluetooth connection is enabled in the user's device as well as in other people's devices.

Create a component diagram that represents the system. This diagram should at least include:
* User
* People In proximity
* Location
* Time interval of proximity "session"

Try to think of the possible interfaces and extensions to the system, for example, privacy, permissions and data storage.

Draw a component diagram of the architecture,** including the most important operations and necessary explanations.
