Internet of Things (IoTs) technology makes every things in physical world being digitalized and communicated with each other. The technology is emerging as a new paradigm and is expected to provide a convenient and effective life. However, for the successful realization of the IoT technologies, IoT security issues are an important prerequisite, and particularly the privacy protection is expected to become more important in view of object communication directively related with human. In this paper we describe for the security and privacy threats in IoT environment and introduce the shodan (a legitimate search engine that finds backdoor routers, switches, webcams, IoT devices connected to the Internet etc.) that can expose the security and privacy problems. Lastly, we compare the privacy threats through real-world case study of network cameras currently in use and finally derive the countermeasures for the threats.

This research aims to empirically explore the antecedents that could impact on internet users' information protection behavior. 282 of sample data collected from internet users was used to test the hypotheses. The results of this research reveal that the internet users' information privacy concerns has a significant impact on self-efficacy, perceived usefulness, and information protection behavior. In addition, we found that perceived usefulness and information protection behavior are significantly influenced by self-efficacy. However, contrary to expectations, perceived usefulness has no statistically significant effect on information protection behavior. These findings provide significant implications for online companies and internet uses as well as educational stakeholders that give educations about information protection.

The purpose of this study is to find an answer why internet users are unconcern about their privacy information. We found that perceived privacy risk and website usability have a significant effect on privacy unconcern. That is, individuals who have experiences privacy incidents are more likely to be unconcern about their privacy information. Accordingly, organizations who supply services on the web have to pay more attention to these individuals to increase a privacy concern. Implications and Conclusions are discussed.

현재 인터넷의 사용 증가로 인한 개인 정보의 유출이 급증하고 있다. 특히, 인중과 권한의 허가가 동일한 시스템 내에서 이루어지므로 처리에 불필요한 개인 정보가 과다하게 공개되고 있다. 이러한 문제를 해결하기 위해 인중과 권한, 처리를 개별적으로 분리한 프라이버시 속성 인증 제어 시스템 모델이 제시되어 있다. 그러나 프라이버시 보호를 위한 처리모델은 서버로 하여금 서비스 이용자의 각종 지원 서비스와 서버 운영 통계 처리 분석을 불가능하게 한다. 본 논문에서는 공개 가능한 개인 속성 정보만을 선별적으로 참조 가능하게 하는 프라이버시 속성 인중 네트워크 프레임으로 확장하기 위한 모델을 제안한다.

One's identity on the Internet has been disclosed and abused without his consent. Personal information must be protected by appropriate security safeguard. An Individual should have the right to know whether his personal details have been collected and stored. This paper proposes various conceptual models for designing privacy enabling service architecture in the Internet identity management system. For the restriction of access to personal information, we introduce the owner's policy and the management policy The owner's policy should provide the user with enough information to manage easily and securely his data. To control precisely and effectively all personal information in the Identity provider, we propose the privacy management policy and the privacy authorization model.

It is expected that internet of things can be used for various fields such as smart home, smart building and smart city as the representative case of ICT that sensor, communication and interface technologies operate organically and the researches of the technologies regarding internet of things are being carried out in each countries worldwide. However, many problems rise against internet of things continuously in respect of security. Among them, the problem of privacy is the one that should be solved definitely regarding internet of things. If user data does not remain during the process of user authentication, such the privacy problem can be solved. In this paper, we propose the framework of user authentication based on OAuth that is suitable for the environment of internet of things that can solve privacy problem and analyze its security.

Internet cookie technology is designed for solving unreliable problem of HTTP's inherent property and notifying user's previous activity to web site's server, so it is useful to provide suitable service for individual user. However, the cookie techniques are becoming more sophisticated such as the third cookie and super cookie. And its included information is applied for advertisement and target marketing strategy, so the problem occurs that user's personal information is collected excessively. However, our law does not recognize the internet cookie as personal information so user cannot know where own internet cookie is stored and applicable. Therefore, in this paper, we explain the internet cookie technology, the privacy invasion and right to be forgotten for solving problem due to the internet cookie. And we analysis the relationship between the information of internet cookie and personal information, and then present the improvement requirement on the law and technology to use internet cookie securely and conveniently.

Increasingly important user based service on the smart media era, and increasing awareness about the user experience. As the connected Internet information systems increases, one of the problems happening between users and information systems such as Internet shopping-malls, portal sites, and corporate web sites is related with the information privacy concerns issues. In this research, we aim to analyze factors influencing of the invasion of privacy on continue using intention in online environment. Based on these findings, several theoretical and practical implications were suggested and discussed. Thus, we have reviewed extensive previous studies on information privacy in local and foreign information systems, marketing and other fields. The purpose of this study is to provide future directions of studies on information privacy concerns by analyzing past and recent trends of the studies.
