Background: This paper is based on Theory of Information Ethics (IE) interpreted by Luciano Floridi to be definite as a developing filed of Computer Ethics (CE), and it considers a necessity for classification of important ethical problems in the field to give a methodic attitude to analyze any class of the problems. Floridi argued that the purview of computer ethics- indeed of ethics in general- should be widened to include much more than simply human beings, their actions, intentions and characters. He offered IE as another macroethics which is intended to be applicable to all ethical situations.Methods: First of all, some of the typical problems in the information age are surveyed by a problem-based approach to be recognizing the evolution and the developing process from CE field to IE field. To introduce IE in detail and to explain its typical problems, four fundamental possible approaches of ethics are considered: philosophical, normal, descriptive, and applied ethics. Therefore, IE is granted as a research filed in the ethical problems that arises from information & communication technology in the information age., These problems as the applied ethical problems are distinguished in three different approaches to IE with the typical issues and examples: philosophical, professional, and descriptive ethics approaches.Conclusion: The approaches to IE are classified in a table. Therefore, the associated disciplines, the typical issues, and the appropriate methodology are given to analyze any category of the problems that are explained by four possible approaches of ethics in short.
