Computer Crime

A computer crime is generally defined as one that involves the use of computers and software for illegal purposes. This doesn&39;t mean that all the crimes are new types of crime. On the contrary, many of these crimes, such as embezzlement of funds, the alteration of records, theft, vandalism, sabotage, and terrorism, can be committed without a computer. But with a computer, these offenses can be carried out more quickly and with less chance that the person responsible for the crime will be discovered.

Computer crimes are on the rise and have been for the last twelve years. Just how much these 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 of all kinds of crimes, is unable to say precisely how large a loss is involved; however, it estimates that the average take 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 satellite and other data-transmission networks; and (C) the easy access of microcomputers to huge mainframe. data bases.

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 imagination 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".

Difficulty of Detection and Prevention

Given the kind of person who commits a computer 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 that leads back to the guilty party. After all, looking for "weapons" or fingerprints does not occur as it might in the investigation of more conventional crimes.

Third, there are usually no witnesses to the computer crime, even though it may be taking place in a mom filled with people. Who is to say if the person at the next terminal, calmly keying in data, is doing the company&39;s work or committing a criminal act？

Fourth, not enough people in management and law enforcement know enough about computer technology to prevent the crimes. Authorities have to be familiar with the computer&39;s capabilities within a given situation to guard against its misuses. In some large cities, such as LosAngeles, police departments have set up specially trained computer crime units.

But even when an offender is caught, the investigators, attorneys (律师), judges, or juries may find the alleged crime too complicated and perplexing to handle. More attorneys are specializing in computer law and studying the computer&39;s potential for misuse.

After a computer crime has been discovered, many companies do not report it or prosecute (起诉) the person responsible. A company may not announce the crime out of fear that the pubic will find out the weaknesses of its computer system and lose confidence in its organization. Banks, credit card companies, and investment firms are especially sensitive about revealing their vulnerabilities (脆弱性) because they rely heavily on customer trust.

To avoid public attention, cautious companies will often settle cases of computer tampering out of court. And if cases do go to trial and the offenders are convicted, they may be punished only by a fine or light sentence because the judge or jury isn&39;t fully trained to understand the nature and seriousness of the crime. Not all companies 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 technicians had embezzled about200, 000 by entering false benefit claims, it presented it findings to the state’s attorney and aided in the prosecution of the technician. The technician was found guilty and sentenced to prison, not just for the computer misuse, but also for grand theft and insurance fraud. Connecticut General now has a policy of reporting all incidents of theft or fraud, no matter how small.

Task 2

Directions: This task is the same as Task 1. The 5 questions or unfinished statements are numbered 41 through 45.

Cyber crime which is the illegal activity committed on the Internet is the fastest growing criminal activity in the world and is of major concern to the Government. From traditional crime on-line to new crimes that target information and communications networks, it covers a huge range of unlawful activities. UK and international agencies are working together to combat the threat of cyber crime.

Access to information and communications technology (ICT) is globally available and increasingly used. Most Internet and e-mail users are involved in lawful business. However, some use the technology for unlawful activities. Global and transnational crimes can now be committed far distant from the place (or places) where the impact of that crime is felt.

Transnational hi-tech crime involves the criminal's computer communicating by using a number of other machines to reach its intended target. This activity leaves a data record with the service provider. If the records are retained and the criminal has not concealed them, they can be used to trace the criminal. However, these data records are not permanent. In many cases when law enforcement officials attempt to gain lawful access to this data, it may have been deleted.

As lawful use of IT increases, criminals around the world increasingly use computers to commit traditional crimes. Computer hacking is also an area of concern.

According to the passage, cyber crime refers to ______.

A．the unlawful activities committed by the Internet

B．the illegal activities done by telephoning

C．the unlawful activities done by getting others' digital records

D．the illegal activities committed by hacking others' computers

The man behind this notion, Jack Maple, is a dandy who affects dark glasses, homburgs（翘边

The man behind this notion, Jack Maple, is a dandy who affects dark glasses, homburgs(翘边帽)and two-toe shoes; yet he has become something of a legend in America's police departments. For some years, starting in New York and moving on to high-crime spots such as New Orleans and Philadelphia, he and his business partner, John Linder have marketed a two-tier system for cutting crime.

First, police departments have to sort themselves out: root out corruption, streamline their bureaucracy, and make more contact with the public. Second, they have to adopt a computer system called Comstat which helps them to analyze statistics of all major crimes. These are constantly keyed into the computer, which then displays where and when they have occurred on a color-coded map, enabling the police to monitor crime trends as they happen and to spot high-crime areas. In New York, Comstat's statistical maps are analyzed each week at a meeting of the city's police chief and precinct captains.

Messrs Maple and Linder(" specialists in crime-reduction services")have no doubt that their system is a main contributor to the drop in crime. When they introduced it in New Orleans in January 1997, violent crime dropped by 22% in a year; when they merely started working informally with the police department in Newark, New Jersey, violent crime fell by 13% . Police departments are now lining up to pay as much as $50, 000 a month for these two men to put them straight.

Probably all these new policies and bits of technical wizardry, added together, have made a big difference to crime. But there remain anomalies that cannot be explained, such as the fact that crime in Washington D. C. , has fallen as fast as anywhere, although the police department has been corrupt and hopeless and, in large stretches of the city, neither police nor residents seem disposed to fight the criminals in their midst.

The more important reason for the fall in crime rates, many say, is a much less sophisticated one. It is a fact that crime rates have dropped as the imprisonment rate soared. In 1997 the national incarceration rate, at 645 per 100 000 people was more than double the rate in 1985, and the number of inmates in city and county jails rose by 9.4% .almost double its annual average increase since 1990. Surely some criminologists argue, one set of figures is the cause of the other. It is precise because more people are being sent to prison, they claim that crime rates are falling. A 1993 study by the National Academy of Sciences actually concluded that the tripling of the prison population between 1975 and 1989 had lowered violent crime by 10-15% .

Yet cause and effect may not be so obviously linked. To begin with, the sale and possession of drugs are not counted by the FBI in its crime index, which is limited to violent crimes and crimes against property. Yet drug offences account for more than a third of the recent increase in the number of those jailed; since 1980, the incarceration rate for drug arrests has increased by 1000% . And although about three-quarters of those going to prison for drug offences have committed other crimes as well, there is not yet a crystal-clear connection between filling the jails with drug-pushers and a decline in the rate of violent crime. Again, though national figures are suggestive, local ones diverge: the places where crime has dropped most sharply(such as New York City)are not always the places where incarceration has risen fastest.

Jack Maple started his career in______.

A．Philadelphia

B．Oregon

C．New Orleans

D．New York

听力原文： In many businesses, computers have largely replaced paperwork, because they are

fast and do not make mistakes. Many banks put advertisements in the newspaper showing that their business deals are "untouched by human hands" and therefore safe from human temptation. Obviously, computers have no reason to steal money. But the growing number of computer crimes shows they can be used to steal. Computer criminals don't use guns. And even if they are caught, it is hard to punish them because there are no witnesses and often no evidences. A computer cannot remember who used it; it simply does what it is told. One clerk at a New York City bank used a computer to steal more than one and a half million dollars in just four years. No one noticed this because he moved money from one account to another. Each time a customer he had robbed questioned the balance in his account, the clerk claimed a computer error, then replaced the missing money from someone else's account. This clerk was caught only because he was gambling. When the police broke up an illegal gambling operation, his name was put in the records. Most computer criminals have been minor employees. But police wonder if this is true. As one official say, "I have a feeling that there is more crime out there than we are catching. What we are seeing now is all so poorly done. I wonder what the real experts are doing--the ones who really know how a computer works."

In May 2004, agents from the Federal Bureau of Investigation （FBI) showed up at Brandon Ma

In May 2004, agents from the Federal Bureau of Investigation (FBI) showed up at Brandon Mayfield's law office and arrested him in connection with the March 2004 bombing of a train station in Madrid(马德里), Spain. The Oregon lawyer was a suspect (嫌犯)because several experts had matched one of his fingerprints to a print found near the scene of the terrorist attack.

But Mayfield was innocent (清白的). When the truth was found 2 weeks later, he was set free from jail. Still, Mayfield had suffered unnecessarily(受罪), and he's not alone.

Police officers often use fingerprints successfully to catch criminals. However, according to a recent study by criminologist(犯罪学家) Simon Cole of the University of California, Irvine, authorities may make as many as 1,000 incorrect fingerprint matches each year in the United States.

"The cost of a wrong decision is very high," says Anil K. Jain, a computer scientist at Michigan State University in East Lansing.

Jain is one of a number of researchers around the world who are trying to develop improved computer systems for making accurate fingerprint matches. These scientists sometimes even engage in competitions in which they test their fingerprint-verification (核实) software to see which way works best.

The work is important because fingerprints have a role not just in crime solving but also in everyday life. A fingerprint scan may someday be your ticket to getting into a building, logging on to a computer, withdrawing money from an ATM, or getting your lunch at school.

The title of this article most probably is ______.

A．Fingerprint Evidence

B．Fingerprint and Computer

C．The Mistakes of Fingerprinting

D．Fingerprint Matching

In many businesses, computers have largely replaced paperwork, because they are fast, flex

ible, and do not make mistakes. As one banker said, "Unlike humans, computers never have a bad day. " And they are honest. Many banks advertise that their transactions are "untouched by human hands "and therefore safe from human temptation. Obviously, computers have no reason to steal money. But they also have no conscience, and the growing number of computer crimes shows they can be used to steal.

Computer criminals don't use guns. And even if they are caught, it is hard to punish them because there are no witnesses and often no evidence. A computer cannot remember who used it, it simply does what it is told. The head teller at a New York City Bank used a computer to steal more than one and a half billion dollars in just four years. No one noticed this theft because he moved the money from one account to another. Each time a customer he had robbed questioned the balance in his account, the teller claimed a computer error, then replaced the missing money from someone else's account. This man was caught only because he was a gambler. When the police broke up an illegal gambling operation, his name was in the records.

Some employees use the computer's power to get revenge on employers they consider unfair. Recently, a large insurance company fired its computer-tape librarian for reasons that involved her personal rather than her professional life. She was given thirty days' notice. In those thirty days, she erased all the company's computerized records.

Most computer criminals have been minor employees. Now police wonder if this is "the tip of the iceberg". As one official says, "I have the feeling that there is more crime out there than we are catching. What we are seeing now is all so poorly done. I wonder what the real experts are doing—the ones who really know how a computer works. "
