Wearable Bluetooth devices hide more risks
According to statistics, there are billions of smart devices around the world using Bluetooth technology. Although Wi-Fi can replace Bluetooth to meet the user's wireless transmission needs, but in wireless headphones, speakers and other devices, usually equipped with Bluetooth and Wi-Fi functions.
"Wireless speakers, in-car infotainment systems, these Bluetooth-enabled devices usually only involve point-to-point single-wire transmission and almost no other devices, so they are less likely to reveal privacy. For example, wireless headphones usually only connect to the user's own mobile phone or other personal device, not to the device of others." Huang Xinyi said, but smart wearable devices with Bluetooth function related to sports and health, such as smart bracelets, smart glasses, smart sports shoes, etc., will upload personal information such as heart rate, sleep and body fat of users to the server through mobile phone software, that is, non-personal user devices, which will have a greater risk of privacy disclosure.
