This paper proposes a scheme to collect video data of the vehicle black box in order to strengthen the public safety. The existing schemes, such as surveillance system with the fixed CCTV and car black box, have privacy issues, network traffic overhead and the storage space problems because all video data are sent to the central server. In this paper, the central server only collects the video data related to the accident or the criminal offense using the GPS information and time in order to investigation of the accident or the criminal offense. The proposed scheme addresses the privacy issues and reduces network traffic overhead and the storage space of the central server since the central server collects the video data only related to the accident and the criminal offense. The implementation and experiment shows that our service is feasible. The proposed service can be used as a component of remote surveillance system to prevent the criminal offense and to investigate the criminal offense.

Life log started with the simple purpose of recording or sharing mainly data regarding one's personal life, but with the introduction of advanced specialized analytic methods by many corporations, a new type of business based on the life log recently emerged, with an aim of improving the quality of people's personal lives. In spite of the indispensable advantages, however, personal health lifelog service brings critical challenges that cannot be avoided from user side if the security of the data is concerned. The problem of user's privacy infringement and leaking user's sensitive medical information is increasing with the revitalization of personal health lifelog services. In this paper, we propose an information security reference model for the personal health lifelog services. Our proposal can contribute to increase the related industry to cultivate new market by suggesting the clear announcement of the guidelines using privacy protection reference model for user-specific healthcare services which uses personal lifelog.

The various kinds of application is distributed for the Smart phone user recently. There is the advantage that the open source application on Android operating system based Smart phone supports a multi tasking service. Layar, Wikitude, and Sherpa and the other applications using the GPS location information like an a2b etc. were developed in the Smart phone environment. However, the existing Cell-ID based location information can be directly collected by the mobile ISP unit which the mobile carrier installs, the personal privacy problem occurs. Therefore, the personal location information is possible to be exposed publicly without any access control procedure. Therefore, in this research, the self-control mechanism on the GPS location information at the Smart phone is designed and presented. Through this, it is possible to develop diverse applications providing enhanced access control and GPS location management on the Android based Smart Phone.

This research was based on the investigation of the awarenesses of librarians of issues regarding the privacy of the users of school libraries. It sought to determine if, by raising the issue of the importance of the need for the protection of the personal information of the users of the school libraries, and the implications of not paying attention to the rules in effect, the awareness regarding the privacy of the users of school libraries would be improved. For this, previous research related to the privacy of the students, the legal basis for the protection of the privacy of the domestic and foreign students, and the types of the infringements upon the protection of their personal information were investigated. A survey was conducted to measure the awareness of issues related to the privacy of the users of the library. The research showed the results as follows: First, the awarenesses regarding the privacy of the users of the school libraries appeared low, and low recognition was also found regarding the awareness of the cases of the infringements upon the privacy of the users of the school libraries; regarding the awareness in relation to the protection of privacy; regarding the seriousness of the privacy problems of the users; and regarding the factors that can encroach upon the privacy of the users. Second, regarding the seriousness felt when the library records of the users of the school libraries are leaked to the outside, 41.6% of the respondents responded by saying "It is serious", and 18.4% responded by saying "It is not serious". Third, as a result of investigating the awareness regarding whether the consent of the person concerned is needed in case a third party requests access to reading the records in the library, 68.5% of the respondent responded "It is needed", and only 10.4% responded "It is not needed". Last, in the investigation into whether the respondents had the experience of being educated as to the rules related to the privacy of the users at a school or an external organization, over 80% of the respondents answered that they did not receive it.

The purpose of this research was to analyze the effect of consumer innovativeness on the evaluation of online fashion advertisement sustainability and on purchase intentions of advertising products. Online survey have been conducted of 573 people who had experience of online advertisements. The data collected from the surveys were analyzed by the factor analysis, the t-test and the multiple regression analysis. the results are as follows: Firstly, it has been identified that the concept of sustainability of online fashion advertisement consists of four sub-elements of the objectivity of advertisement expressions, the non-harmfulness of advertisement expressions, the protection of personal information, and the non-infringement of web use. Secondly, the group that has a higher consumer innovativeness shows a significantly higher experience of online advertisements as well as more many internet use hours than those who have a lower consumer innovativeness. In addition, comparing with the group that shows lower consumer innovativeness, the group who has higher consumer innovativeness shows a significantly higher recognition of the protection of personal information, the non-infringement of web use and the objectiveness of advertisement expressions among the sub-elements of online fashion advertisement. Lastly, the objectiveness of advertisement expressions and the non-infringement of web use significantly affect the intentions of the group that has high consumer innovativeness to purchase advertised products, and the purchase intentions of those who have low consumer innovativeness are significantly affected by the objectiveness of advertisement expressions and the protection of personal information.

Search engines provide web documents that are related to user's query. However, using only the query terms that user provided, it is hard for search engines to know user's exact intention and provide the very matching web documents. To remedy this problem, search systems are needed to exploit personalized search technologies. In this paper, we propose not only a novel personalized query recommendation scheme based on folksonomy but also a new personalized search service architecture which reduces the risk of privacy violation while enabling search service providers to provide other various personalized services such as personalized advertisement.

Recently invasion of privacy problem in medical information have been issued following the interest in secondary use of large medical information. These large medical information is very useful information that can be used in various fields such as disease research and prevention. However, due to the privacy laws such as Privacy Act and Medical Law, these informations including patients or health professionals' personal information are difficult to utilize secondary. Accordingly, various methods such as k-anonymity, l-diversity and differential-privacy that can be utilized while protecting privacy have been developed and utilized in this field. In this paper, we study differential privacy processing procedure, one of various methods, and find out about the differential privacy problem using Laplace noise. Finally, we propose a new method using the Shamir's secret sharing method and symemetric key encryption algorithm such as AES for this problem.

All medical information over sensor networks need to transmit and process securely in the u-Health services. The reliability of transmission between u-Health medical sensor devices and gateway is very important issue. When the user moves to other place with u-Health devices, its signal strength is going down and is far from the coverage of gateway. In this case, Malicious user can be carried out an intrusion under the situation. And also rogue gateway can be tried to steal medical information. Therefore, it needs mutual authentication between sensor devices and gateway. In this paper, we design a mutual authentication protocol which divided sessions from an authenticated session are updated periodically. And in order to reduce the traffic overhead for session authentication, we also introduce dynamic session management according to sampling rate of medical sensor type. In order to verify this, we implemented the programs for the test-bed, and got an overall success from three types of experiment.
