Privacy

     With the development of the new media,m a privacy has become a big issue. Not only that anything you post online can be seen by millions of people, but things that you don't want people to know can be seen by some people. For a hacker it is enough to send an advertising e-mail and when the person opens it, a hacker has a free access to that person's computer, he/she can see all the passwords that that person types, anything that this person has on his/hers computer, and any information such social security number or password to the bank account can be seen and used by hacker. And not only hacker can do it, it can be done by any person who studied computer science.
