Abstract: Embodiments of the disclosure provide a method, device and computer readable medium for protecting MAC addresses. According to embodiments of the present disclosure, the terminal device may obtain a set of virtual MAC addressed from a network device and may connect with a further network device (for example, Wi-Fi AP or Bluetooth devices) using the virtual MAC addresses. In this way, tracking the terminal device with MAC address is prevented so that user privacy protection could be enhanced.
