“…Others have also researched about possible features of subjects' sense of security and privacy for video surveillance systems (Koshimizu et al, 2006;Babaguchi et al, 2009). Results showed how subjects classify viewers that monitor them using cameras in: familiar persons, unfamiliar persons and persons in duty.…”

Recent advances in computer vision technologies have made possible the development of intelligent monitoring systems for video surveillance and ambientassisted living. By using this technology, these systems are able to automatically interpret visual data from the environment and perform tasks that would have been unthinkable years ago. These achievements represent a radical improvement but they also suppose a new threat to individual's privacy. The new capabilities of such systems give them the ability to collect and index a huge amount of private information about each individual. Next-generation systems have to solve this issue in order to obtain the users' acceptance. Therefore, there is a need for mechanisms or tools to protect and preserve people's privacy. This paper seeks to clarify how privacy can be protected in imagery data, so as a main contribution a comprehensive classification of the protection methods for visual privacy as well as an up-to-date review of them are provided. A survey of the existing privacy-aware intelligent monitoring systems and a valuable discussion of important aspects of visual privacy are also provided.

“…Buchanan et al's findings provide a very interesting insight into the attitude−>behavior link, but the authors do not try to classify participants in terms of their disclosure behavior. Koshimizu et al (2006) apply exploratory factor analysis and clustering to data on participants' feelings about a community-based video surveillance system. They find seven factors and three main clusters of participants differing in their attitudes towards social and authoritative surveillance.…”

In studies of people's privacy behavior, the extent of disclosure of personal information is typically measured as a summed total or a ratio of disclosure. In this paper, we evaluate three information disclosure datasets using a six-step statistical analysis, and show that people's disclosure behaviors are rather multidimensional: participants' disclosure of personal information breaks down into a number of distinct factors. Moreover, people can be classified along these dimensions into groups with different "disclosure styles". This difference is not merely in degree, but rather also in kind: one group may for instance disclose location-related but not interestrelated items, whereas another group may behave exactly the other way around. We also found other significant differences between these groups, in terms of privacy attitudes, behaviors, and demographic characteristics. These might for instance allow an online system to classify its users into their respective privacy group, and to adapt its privacy practices to the disclosure style of this group. We discuss how our results provide relevant insights for a more user-centric approach to privacy and, more generally, advance our understanding of online privacy behavior.

In a telework scenario, the lack of informal communications, such as impromptu meetings, is a hard-to-solve problem for those who work at home over the long term. To facilitate informal communication, a system called media space provided an always-on audiovisual connection between distributed workers. Moreover, recent studies suggested that telepresence robots featuring audiovisual capabilities like media space are effective for informal communication. However, in practical use, various problems exist. Therefore, in this paper, we survey the systems of media space and telepresence robots concerning the advantages, problems, and solutions. We also discuss the unresolved issues and required investigations. One of the unresolved issues is that a stationary or desktop robot has a difficulty in initiating informal communication because it cannot move around the office. To tackle the issue, we introduce our experiment suggesting that a robot emulating the social greeting process actually promotes informal communication compared with no emulation.
