But with a computer, there offenses can be carried out more quickly and with less chance that the person responsible for the crime will be discovered. Computer crimes have been on the rise for the l

4、ast twelve years. Just how much their computer crimes cost the American public is in dispute, but estimates range from $ 3 billion to $ 5 billion annually. Even the FBI, which attempts to keep track of the growth or decline to all kinds of crimes, is unable to say precisely how large a loss is invol

5、ved; however, it estimates that the average takes from a company hit by computer crime is $ 600,000. A number of reasons are given for the increase in computer crime: (a) More computers in use and, thus, more people who are familiar with basic computer operation; (b) more computers tied together in

6、satellite and other data-transmission networks; and (c) the easy access of microcomputers to huge mainframe data bases. Examples of Computer Crime Computer crime or e-crime is a kind of crime related to computer. Exactly what is illegal varies greatly from territory to territory. Consequently, the g

The Criminal Movies and newspaper stories might lead us to believe that most computer crimes are committed by teenage “hackers“ brilliant and basically good children who let their imagi

10、nation and technical genius get them into trouble, but a realistic look at the crimes reveals that the offender is likely to be an employee of the firm against which the crime has been committed, i. e. an “insider“.

11、er crime and the environment in which the crime occurs, it is often difficult to detect who the criminal is. First of all, the crime may be so complex that months or years go by before anyone discovers it. Second, once the crime has been revealed, it is not easy to find a clear trail of evidence tha

Third, there are usually no witnesses to the computer crime, even though it may be taking place in a room filled with people. Who is to s

And if cases go to trial and the offenders are convicted, they may be punished only by a fine or light sentence because the judge or jury isnt fully trained to understand the nature and seriousness of the crime. Not all comp

18、anies are timid in apprehending computer criminals. For example, Connecticut General Life Insurance Company decided it had to get tough on violators. So when the company discovered that one of its computer technician has embezzled $ 200,000 by entering faults benefit claims, it presented it findings

19、 to the states attorney and aided in the prosecution of the technician.
