    How can we keep our personal information off the Internet?
    As is reported，more and more people are annoyed by strangers because our personal information，such as phone numbers，emails and so on，is exposed to the Internet.
    It’s almost impossible to keep all personal information off the Internet.However，we can take some measures to minimize the amount of information we reveal as we travel the Internet.
    First，shopping online is the ultimate in convenience，but we must make sure that the checkout page on the site is secure.Secondly，we can only provide information to sites that promise not to share it without our permission and avoid giving permission to share our information with “selected partners”.Besides，we shouldn’t post too much information on social networking sites，message boards and chat rooms.And chat rooms are meant for sharing.And if we blog，we should be careful not to reveal too much about ourselves.
    Obviously，the larger an online presence we have，the more information about us there is going to be online.An online presence is not necessarily a bad thing，as it can open a whole world of opportunities.
