Abstract : In order to create a genuine sense of information-sharing, a problem-solving facility must be able to protect the privacy of a user's files and make information-sharing voluntary. Once a user learns that his files would be free from the invasion of privacy, he may gain confidence in using the facility. The objective of this dissertation is to discuss a pilot model for demonstrating the feasibility of a file system (1) that has the capability of managing files and providing system components to a user's program, and the potential to grow in terms of data, programs and file management functions; (2) that can protect the privacy of a user's information; (3) that enables a file owner to share gradually and voluntarily his information with others. The solution to (1) leads to the development of a centralized file organization and a centralized file system with the capability of automatic file creation, generation and maintenance. The solution to (2) leads to the incorporation of a protection mechanism in the file system. The solution to (3) results in the concept of file ownership and its authority. (Author)
