Imagine you are walking through deep snow.As you walk，you leave footprints where you've been.That's what happens when using technology，such as computers，mobile phones and tablets.You leave your digital footprint and it will never disappear.
Here are reasons why your digital footprint should matter to you.
How people see you
Of course，you have nothing to hide，but if people get information about you，they might judge you from the information you have left online.For example，you make a bad joke online.Years later，it's found by the university you are applying to，and they don't think it's funny.Maybe they decide you are not the"right"kind of person for them.
Your private information
Not everything can be shared with everyone，F(xiàn)or example，you might share your school reports with your parents，but keep them secret to your e-friends.If you share them on the Internet，they will not be a secret anymore.Therefore，to protect your privacy（隱私），remember to put out less information online.
Keeping your money safe
There are plenty of people looking at information about you，and some of them want to steal from you.So you shouldn't write bank details，card numbers or passwords in emails or text messages.
Overall，the message is：No one can go online without leaving his digital footprint—but with care，you can control it.
