Bluetooth is short range wireless technology which is used to transfer files over a fixed range using UHF which are given by the ism for communication from 2.402 ghz to 2.48 ghz and build personal area network. Bluetooth uses radio waves for the transfer of files unlike cables and other means of sharing data. So there is a chance of manipulation of data or hack of data if the attacker has full information how bluetooth works and how he can hack into peoples network but there are security measures that can help users to protect there data and themselves when they use there devices.
