With the dramatic development in the technology of computers and communications, the world has certainly benefited a lot, but the price might also be very expensive. Computer crimes are now becoming very serious problems that are costing up to billions of dollars. The US, where the computer was invented and where the Internet was developed, is considered to be the motherland of the worst computer crimes so far. Other countries are also contracting this problem as their governments, businesses and individuals become more dependent on computers and networks. Computer crimes are threatening the future of communication, confidentiality and even the integrity of businesses and organizations.
