Computer ethics is a part of practical philosophy concerned with how computing professionals should make decisions regarding professional and social conduct. Margaret Anne Pierce, a professor in the Department of Mathematics and Computers at Georgia Southern University has categorized the ethical decisions related to computer technology and usage into three primary influences: The individual's own personal [ethical] code. Any informal code of ethical conduct that exists in the work place. Exposure to formal codes of ethics. Foundation Computer ethics was first coined by Walter Maner, a professor at Bowling Green State University. Maner noticed ethical concerns that were brought up during his Medical Ethics course at Old Dominion University became more complex and difficult when the use of technology and computers became involved. The conceptual foundations of computer ethics are investigated by information ethics, a branch of philosophical ethics promoted, among others, by Luciano Floridi. History The concept of computer ethics originated in the 1940s with MIT professor Norbert Wiener, the American mathematician and philosopher. While working on anti-aircraft artillery during World War II, Wiener and his fellow engineers developed a system of communication between the part of a cannon that tracked a warplane, the part that performed calculations to estimate a trajectory, and the part responsible for firing. Wiener termed the science of such information feedback systems, "cybernetics," and he discussed this new field with its related ethical concerns in his 1948 book, Cybernetics. In 1950, Wiener's second book, The Human Use of Human Beings, delved deeper into the ethical issues surrounding information technology and laid out the basic foundations of computer ethics. A bit later during the same year, the world's first computer crime was committed. A programmer was able to use a bit of computer code to stop his banking account from being flagged as overdrawn. However, there were no laws in place at that time to stop him, and as a result he was not charged. To make sure another person did not follow suit, an ethics code for computers was needed. In 1973, the Association for Computing Machinery (ACM) adopted its first code of ethics. SRI International's Donn Parker, an author on computer crimes, led the committee that developed the code. In 1976, medical teacher and researcher Walter Maner noticed that ethical decisions are much harder to make when computers are added. He noticed a need for a different branch of ethics for when it
