Question

- GPS

- Base station localisation

- Wi-Fi-hotspot-based localisation

- Bluetooth beacon-based localisation

Some of these are normally one-way; the device receives information but doesn't communicate in the other direction. Others are inherently two-way.

i.) Identify which of 1-4 above are one-way, and which are two-way.

ii.) Explain briefly why two-way communication may have implications for privacy.

C) Briefly describe one application of Bluetooth beacons, and how the beacons would be used

Answer 1

Answer i.) GPS is a one-way communication.

Base station localisation is a two way communication.

Wi-Fi-hotspot-based localisation is a two way communication.

Bluetooth beacon-based localisation is a one-way communication.

Answer ii.) Two-way communication requires response from the other party, when a receiver gets message from the sender , they send back response to the sender, but there is some privacy issues like hacking, tracking, Data can be received by third party.

Data can be modified or misused by other threats.

Answer c.) Bluetooth beacons are hardware transmitters, a Smartwatches can be an application in future , this technology enables smartphones,tablets and other devices to perform actions when in close proximity to a beacon.

Bluetooth beacons use Bluetooth low energy proximity sensing to transmit a universally unique identifier picked up by a compatible app or operating system.
