Lately, another problem has arisen: identity theft.     People known as hackers find out personal information such as credit card numbers and use itto their advantage and at their victims’ cost. Some seven million people had their on-line informationstolen and used against them last year in the U.S. As this crime grows, so should people’sunderstanding of the technology they use, or they will understand－the hard way－the meaning of adouble-edged sword.
