No matter which re-definition of computer ethics one chooses, the best way to understand the nature of the field is through some representative examples of the issues and problems that have attracted research and scholarship. Consider, for example, the following topics:
As a "universal tool" that can, in principle, perform almost any task, computers obviously pose a threat to jobs. Although they occasionally need repair, computers don't require sleep, they don't get tired, they don't go home ill or take time off for rest and relaxation. At the same time, computers are often far more efficient than humans in performing many tasks. Therefore, economic incentives to replace humans with computerized devices are very high. Indeed, in the industrialized world many workers already have been replaced by computerized devices -- bank tellers, auto workers, telephone operators, typists, graphic artists, security guards, assembly-line workers, and on and on. In addition, even professionals like medical doctors, lawyers, teachers, accountants and psychologists are finding that computers can perform many of their traditional professional duties quite effectively.
The employment outlook, however, is not all bad. Consider, for example, the fact that the computer industry already has generated a wide variety of new jobs: hardware engineers, software engineers, systems analysts, webmasters, information technology teachers, computer sales clerks, and so on. Thus it appears that, in the short run, computer-generated unemployment will be an important social problem; but in the long run, information technology will create many more jobs than it eliminates.
Even when a job is not eliminated by computers, it can be radically altered. For example, airline pilots still sit at the controls of commercial airplanes; but during much of a flight the pilot simply watches as a computer flies the plane. Similarly, those who prepare food in restaurants or make products in factories may still have jobs; but often they simply push buttons and watch as computerized devices actually perform the needed tasks. In this way, it is possible for computers to cause "de-skilling" of workers, turning them into passive observers and button pushers. Again, however, the picture is not all bad because computers also have generated new jobs which require new sophisticated skills to perform -- for example, "computer assisted drafting" and "keyhole" surgery.
In this era of computer "viruses" and international spying by "hackers" who are thousands of miles away, it is clear that computer security is a topic of concern in the field of Computer Ethics. The problem is not so much the physical security of the hardware (protecting it from theft, fire, flood, etc.), but rather "logical security", which Spafford, Heaphy and Ferbrache [Spafford, et al, 1989] divide into five aspects:
Malicious kinds of software, or "programmed threats", provide a significant challenge to computer security. These include "viruses", which cannot run on their own, but rather are inserted into other computer programs; "worms" which can move from machine to machine across networks, and may have parts of themselves running on different machines; "Trojan horses" which appear to be one sort of program, but actually are doing damage behind the scenes; "logic bombs" which check for particular conditions and then execute when those conditions arise; and "bacteria" or "rabbits" which multiply rapidly and fill up the computer's memory.
Computer crimes, such as embezzlement or planting of logic bombs, are normally committed by trusted personnel who have permission to use the computer system. Computer security, therefore, must also be concerned with the actions of trusted computer users.
Another major risk to computer security is the hacker who breaks into someone's computer system without permission. Some hackers intentionally steal data or commit vandalism, while others merely "explore" the system to see how it works and what files it contains. These "explorers" often claim to be benevolent defenders of freedom and fighters against rip-offs by major corporations or spying by government agents. These self-appointed vigilantes of cyberspace say they do no harm, and claim to be helpful to society by exposing security risks. However every act of hacking is harmful, because any known successful penetration of a computer system requires the owner to thoroughly check for damaged or lost data and programs. Even if the hacker did indeed make no changes, the computer's owner must run through a costly and time-consuming investigation of the compromised system [Spafford, 1992].
One of the earliest computer ethics topics to arouse public interest was
privacy. For example, in the mid-1960s the American government already had
created large databases of information about private citizens (census data, tax
records, military service records, welfare records, and so on). In the US
Congress, bills were introduced to assign a personal identification number to
every citizen and then gather all the government's data about each citizen
under the corresponding ID number. A public outcry about "big-brother
government" caused Congress to scrap this plan and led the
The variety of privacy-related issues generated by computer technology has led philosophers and other thinkers to re-examine the concept of privacy itself. Since the mid-1960s, for example, a number of scholars have elaborated a theory of privacy defined as "control over personal information". On the other hand, philosophers Moor and Tavani have argued that control of personal information is insufficient to establish or protect privacy, and "the concept of privacy itself is best defined in terms of restricted access, not control" [Tavani and Moor, 2001] (see also [Moor, 1997]).
Questions of anonymity on the internet are sometimes discussed in the same context with questions of privacy and the internet, because anonymity can provide many of the same benefits as privacy. For example, if someone is using the internet to obtain medical or psychological counseling, or to discuss sensitive topics (for example, AIDS, abortion, gay rights, venereal disease, political dissent), anonymity can afford protection similar to that of privacy. Similarly, both anonymity and privacy on the internet can be helpful in preserving human values such as security, mental health, self-fulfillment and peace of mind. Unfortunately, privacy and anonymity also can be exploited to facilitate unwanted and undesirable computer-aided activities in cyberspace, such as money laundering, drug trading, terrorism, or preying upon the vulnerable (see [Marx, 2001] and [Nissenbaum, 1999]).
One of the more controversial areas of computer ethics concerns the intellectual property rights connected with software ownership. Some people, like Richard Stallman who started the Free Software Foundation, believe that software ownership should not be allowed at all. He claims that all information should be free, and all programs should be available for copying, studying and modifying by anyone who wishes to do so [Stallman, 1993]. Others argue that software companies or programmers would not invest weeks and months of work and significant funds in the development of software if they could not get the investment back in the form of license fees or sales [Johnson, 1992]. Today's software industry is a multibillion dollar part of the economy; and software companies claim to lose billions of dollars per year through illegal copying ("software piracy"). Many people think that software should be ownable, but "casual copying" of personally owned programs for one's friends should also be permitted (see [Nissenbaum, 1995]). The software industry claims that millions of dollars in sales are lost because of such copying. Ownership is a complex matter, since there are several different aspects of software that can be owned and three different types of ownership: copyrights, trade secrets, and patents. One can own the following aspects of a program:
A very controversial issue today is owning a patent on a computer algorithm. A patent provides an exclusive monopoly on the use of the patented item, so the owner of an algorithm can deny others use of the mathematical formulas that are part of the algorithm. Mathematicians and scientists are outraged, claiming that algorithm patents effectively remove parts of mathematics from the public domain, and thereby threaten to cripple science. In addition, running a preliminary "patent search" to make sure that your "new" program does not violate anyone's software patent is a costly and time-consuming process. As a result, only very large companies with big budgets can afford to run such a search. This effectively eliminates many small software companies, stifling competition and decreasing the variety of programs available to the society [The League for Programming Freedom, 1992].
Computer professionals have specialized knowledge and often have positions with authority and respect in the community. For this reason, they are able to have a significant impact upon the world, including many of the things that people value. Along with such power to change the world comes the duty to exercise that power responsibly [Gotterbarn, 2001]. Computer professionals find themselves in a variety of professional relationships with other people [Johnson, 1994], including:
|
employer |
-- |
employee |
|
client |
-- |
professional |
|
professional |
-- |
professional |
|
society |
-- |
professional |
These relationships involve a diversity of interests, and sometimes these interests can come into conflict with each other. Responsible computer professionals, therefore, will be aware of possible conflicts of interest and try to avoid them.
Professional organizations in the
Computer ethics today is rapidly evolving into a broader and even more important field, which might reasonably be called "global information ethics". Global networks like the Internet and especially the world-wide-web are connecting people all over the earth. For the first time in history, efforts to develop mutually agreed standards of conduct, and efforts to advance and defend human values, are being made in a truly global context. So, for the first time in the history of the earth, ethics and values will be debated and transformed in a context that is not limited to a particular geographic region, or constrained by a specific religion or culture. This may very well be one of the most important social developments in history. Consider just a few of the global issues:
If computer users in the
The world is very close to having technology that can provide electronic privacy and security on the internet sufficient to safely conduct international business transactions. Once this technology is in place, there will be a rapid expansion of global "cyberbusiness". Nations with a technological infrastructure already in place will enjoy rapid economic growth, while the rest of the world lags behind. What will be the political and economic fallout from rapid growth of global cyberbusiness? Will accepted business practices in one part of the world be perceived as "cheating" or "fraud" in other parts of the world? Will a few wealthy nations widen the already big gap between rich and poor? Will political and even military confrontations emerge?
If inexpensive access to the global information net is provided to rich and poor alike -- to poverty-stricken people in ghettos, to poor nations in the "third world", etc.-- for the first time in history, nearly everyone on earth will have access to daily news from a free press; to texts, documents and art works from great libraries and museums of the world; to political, religious and social practices of peoples everywhere. What will be the impact of this sudden and profound "global education" upon political dictatorships, isolated communities, coherent cultures, religious practices, etc.? As great universities of the world begin to offer degrees and knowledge modules via the internet, will "lesser" universities be damaged or even forced out of business?
The gap between rich and poor nations, and even between rich and poor citizens in industrialized countries, is already disturbingly wide. As educational opportunities, business and employment opportunities, medical services and many other necessities of life move more and more into cyberspace, will gaps between the rich and the poor become even worse?
