Privacy Concerns of Wireless Technologies


  • wireless is used generally to refer to several different technologies that allow devices to connect to one another without wires
    • Radio Frequency Identification
    • Bluetooth
    • Near Field Communications

Radio Frequency Identification (RFID)

Radio Frequency Identification (RFID) is a technology that uses radio waves to transmit data to a receiver.

  • is a way to identify unique items using radio waves
  • main purpose of RFID technology is to allow “tagged” items to be identified and tracked
  • devices that use this technology called a RFID tag or chip
  • many different uses:
    • To track pets
    • track inventory
    • track people or their trips
  • most RFID tags do not contain a battery
    • instead, tags are activated when a receiver is within range and sending out radio waves
    • receiver initiates communication with the tag
    • responds with self-identifying data
    • possible to sniff the data if transmission is not secured
  • Individuals have very little control over the information contained on an RFID tag
  • poses privacy concerns in that it can track a person’s movements and daily habits
  • tracking can be completely secret if you do not know that the items you are carrying contain an RFID tag

Bluetooth

Bluetooth, a short-range wireless communication, was designed to replace data cables that connect devices to one another.

  • Bluetooth compatible devices can pair/connect to each other
  • do not need Wi-Fi or cellular data networks to connect
  • information tracking and exposure is a concern
    • connections are often visible to other Bluetooth users in the vicinity
    • can make them identifiable targets for hackers

Near Field Communication (NFC)

Near Field Communication (NFC) is a short-range wireless technology that works only when two electronic devices are about 5 centimeters apart.

  • does not need to use Wi-Fi or a cellular network
  • Because devices have to be very close together for NFC to work,
    • concerns about information exposure are somewhat mitigated
  • used for tasks such as making mobile payments from a mobile device
