Technology is becoming more and more advanced, and if it falls into the hands of someone who is interested, it will become a tool for crime. Through the sharing of Mark Rober, a user on Youtube, as long as you add a thermal photography device to your iPhone, through the difference in thermal energy, you can clearly see the sequence of keys you have pressed. Isn’t it quite scary? However, this friend also suggested a preventive method, that is, after pressing the password, touch all the buttons with the palm of your hand, and you will have no way of knowing the password. Be careful at all times to prevent these malicious people from succeeding.
When you press the password, the sequence will be displayed as the difference in thermal energy.
Under thermal photography, can you see the difference? 13245.
But there is also a simple way to crack it, which is to touch the buttons with the pads of other fingers when pressing the buttons.
It seems that the combination is confusing.
