activate the options in your Developer otions through the USB debugging option that allows the use of ADB tool to access your phone by a command line. This tool provides the developers and advanced users a way to access the phone or computer tablet through connecting the computer via a USB connection and then perform a number of commands from the computer itself, which could allow a thief access some commands and copy data from your phone to his computer without having to penetrate the lock screen on your phone.
To avoid this problem Android 4.2.2 provides now an option which can identify your computer to connect your phone or your computer tablet (if preparing USB debugging is enabled) and you'll see on the phone a message asking if you want to allow this computer to access the phone, similar to the following message :
If you allowed the access to your computer to your phone or your tablet , it means that your computer has become reliable device.
But if the professional thief try to connect your phone with his own computer where the option USB debugging is enabled, he will not be able to access your phone via ADB because it will not be able to agree on the message shown above because it will be closed by one of the protection ways in the Android (password, painting style. etc).
