People who use wearable gadgets to monitor their health or activity can be tracked with only $70 (£40) of hardware, research suggests.

The work, carried out by security firm Symantec, used a Raspberry Pi computer to grab data broadcast by the gadgets.

The snooping Pi was taken to parks and sporting events where it was able to pick out individuals in the crowds.

Symantec said makers of wearables need to do a better job of protecting privacy and handling data they gather.

‘Serious breach’

The research team used a barebones Raspberry Pi computer to which they added a Bluetooth radio module to help sniff for signals. At no time did the device try to connect to any wearable. Rather, it just scooped up data being broadcast from gadgets close by.
