Privacy-Preserved and Best-effort Provisions of Cyber-I Information to Personalized Services

Abstract—User information is needed for personalized services. However, personalized services are often confused either by information inconsistency and incorrectness or the cold start issue while they gather user information. Even some services, such as social network services, provide user information for personalized services to overcome these problems, they are also facing difficulty of the limited diversity of user information. Additionally, they are only capable of providing existing information. While a Cyber-I (short for Cyber Individual) collects any information of a person in its way to gradually approximate to its user. Certainly, a user information needed by personalized services is also included in a corresponding Cyber-I. Therefore, providing Cyber-I information to personalized services could be more prospecting. In order to provide Cyber-I information to personalized services, there are two main problems should be solved. One is the privacy protection problem. Methods should be designed to provide privacy preservation for user. Another one is the best-effort issue which is about how to make full use of existing Cyber-I information to satisfy personalized services as much as possible. Thus, the goal of this paper is providing Cyber-I information to personalized services by best-efforts provisions, simultaneously provide privacy preservation for Cyber-I. To reach that goal, a Cyber-I Information Provision System (CIPS) is proposed. Keywords—Cyber-I; Real-I; personalized service; privacy preservation; information provisio

Through our research, a general framework has been built to connect heterogeneous devices for spacelog sensing and keeping, new approaches are studied for spacelog representations and retrievals, and concrete prototypes of spacelog applications in testing home and laboratory environments are developed for experiments, evaluations and improvements of the proposed framework and related approaches

Cybermatics: A Holistic Field for Systematic Study of Cyber-Enabled New Worlds

PublishedJournal ArticleThis is the author accepted manuscript. The final version is available from IEEE via the DOI in this record.© 2013 IEEE.Following the two trends of computerization and informatization, another emerging trend is cyberization in which numerous and various cyber entities in cyberspace will exist in cyber-enabled worlds, including the cyber world and cyber-conjugated physical, social, and mental worlds. Computer science and information science, as holistic fields, have, respectively, played important roles in computerization and informatization. Similarly, it is necessary for there to be a corresponding field for cyberization. Cybermatics is proposed as such a holistic field for the systematic study of cyber entities in cyberspace and cyber world, and their properties, functions, and conjugations with entities in conventional spaces/worlds. This paper sets out to explain the necessity and rationale for, and significance of, the proposed field of Cybermatics, what it is and what it encompasses, and how it is related to other fields and areas
