Dynamic and Mobile GIS: Investigating Changes in Space and Time - Chapter 3

Kết hợp tiến bộ công nghệ trong cảm biến vị trí, máy tính di động và truyền thông không dây đang mở ra cơ hội mới và thú vị trong lĩnh vực địa điểm nhận thức tính toán. Nhiều người trong số những cơ hội được Explored Ở những nơi khác trong cuốn sách này (ví dụ: Chương 2, 11-13); Những người khác Đã Được phát triển vào ứng dụng thực tế đó sẽ Cung cấp lợi ích cho một mặt cắt rộng của xã hội, như vậy là chăm sóc người cao tuổi (Stanford, 2002) hệ thống ứng phó. | Chapter 3 Location Privacy and Location-Aware Computing Matt Duckham and Lars Kulik University of Melbourne Australia 3.1 Introduction Combined technological advances in location sensing mobile computing and wireless communication are opening up new and exciting opportunities in the domain of location-aware computing. Many of these opportunities are explored elsewhere in this book e.g. Chapters 2 11-13 others are already being developed into practical applications that will provide benefit to a wide cross section of society such as elder care Stanford 2002 emergency response and E911 systems Werbach 2000 and navigation systems for the visually impaired Helal et al. 2001 . Despite the undoubted future potential of location-aware computing location awareness also presents inherent future threats perhaps the most important of which is location privacy. Most people would not feel comfortable if regularly updated information about their current location were made public any more than we would feel comfortable if information about our home address telephone number age or medical history were public. Our precise location uniquely identifies us more so than our names or even our genetic profile. This chapter examines the foundations of location privacy the factors that affect location privacy and the strategies for managing location privacy. The development of location-aware computing technology and mobile GIS is changing forever the way we interact with information our physical environment and one another. How we deal with location privacy issues will be a determining factor in the ultimate direction of those changes. This chapter begins by exploring the different concepts of privacy and their relevance to location-aware computing and mobile GIS Section 3.2 . Section 3.3 reviews the important privacy characteristics of one of the key enabling technologies for location-aware computing positioning systems. The four classes of privacy protection strategy which form the basis
