Term
Identify and describe clearly the facts.
Definition
Find out who did what to whom, and where, when, and how. In many instances, you will be surprised at the errors in the initially reported facts, and often you will find that simply getting the facts straight helps define the solution. It also helps to get the opposing parties involved in an ethical dilemma to agree on the facts.
Term
Define the conflict or dilemma and identify the higher-order values involved.
Definition
Ethical, social, and political issues always reference higher values. The parties to a dispute all
Term
Identify the stakeholders
Definition
Every ethical, social, and political issue has stakeholders: players in the game who have an interest in the outcome, who have invested in the situation, and usually who have vocal opinions. Find out the identity of these groups and what they want. This will be useful later when designing a solution.
Term
Identify the options that you can reasonably take
Definition
You may find that none of the options satisfy all the interests involved, but that some options do a better job than others. Sometimes arriving at a good or ethical solution may not always be a balancing of consequences to stakeholders.
Term
Identify the potential consequences of your options.
Definition
Some options may be ethically correct but disastrous from other points of view. Other options may work in one instance but not in other similar instances. Always ask yourself, “What if I choose this option consistently over time?”
Term
What are the ethical rules one should use when making a decision.
Definition
Golden rule,(Immanuel Kant’s Categorical Imperative). Ask yourself, “If everyone did this, could the organization, or society, survive?”,(Descartes’ rule of change)An action may bring about a small change now that is acceptable, but if it is repeated, it would bring unacceptable changes in the long run. In the vernacular, it might be stated as “once started down a slippery path, you may not be able to stop.”,Take the action that achieves the higher or greater value (Utilitarian Principle),(Risk Aversion PrincipleSome actions have extremely high failure costs of very low probability (e.g., building a nuclear generating facility in an urban area) or extremely high failure costs of moderate probability (speeding and automobile accidents). Avoid these high-failure-cost actions, paying greater attention to high-failure-cost potential of moderate to high probability.(This is the ethical “no free lunch” rule.) If something someone else has created is useful to you, it has value, and you should assume the creator wants compensation for this work.
Term
Privacy
Definition
s the claim of individuals to be left alone, free from surveillance or interference from other individuals or organizations, including the state. Claims to privacy are also involved at the workplace: Millions of employees are subject to electronic and other forms of high-tech surveillance (Ball, 2001). Information technology and systems threaten individual claims to privacy by making the invasion of privacy cheap, profitable, and effective.
Term
Fair Information Practices (FIP)
Definition
first set forth in a report written in 1973 by a federal government advisory com- mittee (U.S. Department of Health, Education, and Welfare, 1973). FIP is a set of principles governing the collection and use of information about individuals. FIP principles are based on the notion of a mutuality of interest between the record holder and the individual. The individ- ual has an interest in engaging in a transaction, and the record keeper—usually a business or government agency—requires information about the individual to support the transaction. Once information is gathered, the individual maintains an interest in the record, and the record may not be used to support other activities without the individual’s consent.
Term
Europe privacy
Definition
In Europe, privacy protection is much more stringent than in the United States. Unlike the United States, European countries do not allow businesses to use personally identifiable information without consumers’ prior consent.
Term
Informed consent
Definition
can be defined as consent given with knowledge of all the facts needed to make a rational decision. EU member nations must translate these principles into their own laws and cannot transfer personal data to countries, such as the United States, that do not have similar privacy protection regulations.
Term
safe harbor
Definition
is a private, self-regulating policy and enforcement mechanism that meets the objectives of government regulators and legisla- tion but does not involve government regulation or enforcement. U.S. businesses would be allowed to use personal data from EU countries if they develop privacy protection policies that meet EU standards. Enforcement would occur in the United States using self-policing, regulation, and government enforcement of fair trade statutes.
Term

Intellectual property
Definition

Definition
s a statutory grant that protects creators of intellectual property from having their work copied by others for any purpose during the life of the author plus an additional 70 years after the author’s death. For corporate-owned works, copyright protection lasts for 95 years after their initial creation. Congress has extended copyright protection to books, periodicals, lectures, dramas, musical compositions, maps, drawings, artwork of any kind, and motion pictures. The intent behind copyright laws has been to encourage creativity and authorship by ensuring that creative people receive the financial and other benefits of their work.
Term
software copyright
Definition
In general, courts appear to be following the reasoning of a 1989 case—Brown Bag Software vs. Symantec Corp.—in which the court dissected the elements of software alleged to be infringing. The court found that similar concept, function, general functional features (e.g., drop-down menus), and colors are not protectable by copyright law (Brown Bag Software vs. Symantec Corp., 1992).
Term
patent
Definition
grants the owner an exclusive monopoly on the ideas behind an invention for 20 years. The congressional intent behind patent law was to ensure that inventors of new machines, devices, or methods receive the full financial and other rewards of their labor and yet make widespread use of the invention possible by providing detailed diagrams for those wishing to use the idea under license from the patent’s owner.
Term

Term
Digital Millennium Copyright Act (DMCA)
Definition
