　　The day before yesterday,someone gave me a phone call.he said“che ,i am your leader,come to my office room right now”so i felt anxious and said”who are you?and what did i do?”.he just said”i am just your leader”.i realized he is a cheater.so i said”i will call the police”he hung up immediately.so i felt scared.and i have a question:who leak my information? Ten years ago,i have never thought our personal information is important.but now if your phone number is leaked,you will be drowned in a sea of junk short message.the ID card number is one of your most important personal information.because your bank card, driving license, student card and personal resume are both binding to your ID card number.so if your ID card number leaked, that completely is a disaster. How did my information leak? In some film, a hacker use a computer attack a website and get many information.that is true.many computer virus can do this.and today is the age of big data, a good hacker can get your password from your other information.for example,a hacker build a false website, and you register for an account.the hacker would get your password and your email address. Sometimes the password is your bank account password.He just need to send you a e-mail with computer virus.your bank account and password will be leaked. So what should we do to protect our information security? First of all we shouldn’t tell others our personal information.most of the information leakage event is from our carelessness.besides,we shouldn’t register for an account easily.and i still hold a belief on don’t using number is the best way to protect information security
