An invasion of privacy

　First, about an invasion of privacy. When we use the Internet, we must keep in mind that our personal information may leak out from companies and so on. Hackers invade computers of companies, and may leak our information. Or a person in the company may leak our information to outside. Recently, we often hear leaks of the personal information on the news. I’m afraid of this fact. Because I don’t know for what the person who get my information uses it. In addition, if we open our personal information at ease on the Internet, it may be used by others. So, when we use our personal information, we must use caution.
