Internet has penetrated into all the aspects of our life and work. We can study and work by it; we can find a job by it; we can communicate by it; we can entertain by it; we can buy and sell by it. We can do almost everything on the Internet, and almost anywhere anytime.
However, at the same time Internet provides services for us, it is inevitably invading our privacy to some degree. The services on most websites require our registering. If we want to enjoy these services, we have to provide much private information, including our names, gender, address, telephone number and sometimes bank account. Due to the poor Internet administration and weak network security, our information might be open, stolen or sold. Even sometimes the information will be misused by the criminals.
Considering the above-mentioned, we must enhance the alertness when using the Internet. First, when we need Internet service, we should always log on those big legal websites. Second, if the service requires important private information, you should think twice before you type in it.
