One of the challenges in online community management is what level of perceived anonymity can be granted to encourage active participation from members while discouraging unhealthy activities. Few studies developed a scheme of anonymity and investigated how different levels of anonymity influence community activities. This study develops a classification scheme of anonymity encompassing the following three different levels : (1) real name(no anonymity), (2) nickname (partial anonymity), and (3) random assignment of a temporal ID (complete anonymity). Then, it examines how different levels of anonymity influence trust and perceived risk, which in turn affect virtual team performance. A series of laboratory experiments were performed, manipulating the levels of anonymity, in the context of well-structured communities that allow prior interactions among community members. The data was collected from 364 laboratory participants and analyzed using ANOVA and PLS. The results indicate that the difference of anonymity between (2) and (3) had not be significant and the only (1) could not guarantee the anonymity. The impact of anonymity on trust and perceived risk could not be significant in this situation. These findings could contribute to make more beneficial member identification strategies in online community practice.

Online rumor creates psychological stress and image loss for victims. Prior studies related to online rumor did not consider the online environmental factor, despite the fact that online rumor occurs in the online space. Therefore, this study tried to investigate the influence of online characteristics on online rumor. This study considered perceived anonymity, lack of social presence, and perceived dissemination as online characteristics. We established and demonstrated a research model in which online characteristics affect online rumor behavior through attitude toward online rumor. This study obtained the sample of 201 social network users based on the survey and verified the research model using PLS tool. The results provided that perceived anonymity and perceived dissemination influenced online rumor behavior through attitude toward online rumor. On the other hand, lack of social presence was not significant. The findings of this study provide the fact that an individual's online rumor behavior can be caused by online characteristics. This study suggests that we pay attention to the role of perceived anonymity and perceived dissemination for online rumor behavior.

인터넷과 같이 안전하지 않은 네트워크 환경에서 도청은 손쉽게 일어난다. 또한 수신자가 누구인지 알아내기가 쉽다. 이러한 환경에서 정당한 수신자에게 방송 콘텐츠를 안전하게 제공하면서 익명성을 제공하기 위해서는 서버와 수신자 사이에 익명성을 제공하는 키 교환이 필요하다. 스마트 카드를 이용한 익명성을 제공하는 키 교환 프로토콜은 이러한 요건을 충족시킨다. 스마트 카드를 이용한 방법은 여러 가지가 존재하나 이 논문에서는 Kumar Mangipudi 가 제안한 sika프로토콜을 향상시킨 Ren-Chiun Wang의 프로토콜을 알아보고, 취약점을 분석한다. 마지막으로 취약한 점을 보완한 프로토콜을 제안하고 제안한 프로토콜의 안전성을 분석한다. 제안하는 프로토콜은 Ren-Chiun Wang의 프로토콜보다 안전성 측면에서 향상되었다.

환 서명(ring signature)은 서명자가 자신을 포함한 환(ring)을 구성하여 환의 구성원들의 공개키(public key)들을 이용하여 생성하는 서명이다. 검증자의 입장에서는 누가 서명했는지 알 수 없는 서명자 익명성(signer ambiguity)이 가장 중요한 성질이다. 본 논문에서는 서명자가 어떤 특정한 정보를 노출함으로써 실제 서명자가 누구인지 알 수 있는 방식(scheme)을 제안한다. 따라서, 필요하다면 서명자는 자신이 실제 서명자임을 다른 사람들에게 증명할 수 있다.

As malicious comments are emerging as social problems, the solution is needed. Many studies have been conducted in various perspectives to understand and prevent malicious comments. In the previous researches, the neutralization of malicious comments has attracted attention as an important factor explaining the malicious comments, but the difference of the degree of neutralization according to the gender has not been rarely considered. In addition, although there are many environmental characteristics that are different from reality in online, research with malicious comments is insufficient. Based on these facts, this study examined moderating effects of gender on relationship between malicious comments and neutralization, and demonstrated the effects of online environmental factors (anonymity, lack of social presence) on malicious comments. As a result of the study, we discovered that the influence of online environmental factors was not found, but neutralization of malicious comments had strong direct influence on malicious comments and moderating effect of gender difference. Based on the results of this study, we discuss academic and practical implications and suggest limitations of research and future research directions.

Although there have been lots of studies about users' behaviors online, few have explored the mechanism of hostile behaviors. In this sense, this study aims at discovering what may elevate users' hostile behaviors. More specifically, we tried to find the relationship between flaming behavior and perception factors such as perceived risk, anonymity and expected emotional reaction. A survey was conducted to investigate the relationship of the above variables. As a result, all these variables show significant effects on flaming, and information overload are found to act as a moderator. We carefully conclude that flaming in online community can be reduced by preventing information overload each user perceives.

This study investigated the effect of cognitive dissonance that people experience during online communication on face-to-face communication. When people communicate with others on Interne using the comment system, they know that all the people including themselves equally participate in the discussion as one of the many commenters. At the same time, they somewhat distrust other commenters' attitudes because of the Internet anonymity. We name this seemingly contradicting beliefs as cognitive dissonance and examine how these beliefs affect the intention to communicate in face-to-face. Also, the proposed research model includes other factors such as curiosity and the differences in attitudes between online and offline. To verify the hypotheses, a total of 323 comment system users were recruited and show that most of the hypotheses were supported. This study emphasized its implications by examining the reasons when and why people prefer direct communication rather than comment based communication.

디지털 컨텐츠의 지적 재산권 보호를 위한 디지털 워터마킹 기술이 많이 연구되어져 왔다. 핑거프린팅은 디지털 컨텐츠 지적 재산권 보호를 위한 또 다른 기술로서, 디지털 워터마킹에서는 컨텐츠 내부에 소유권자나 판매권자의 정보 가 삽입되는 반면에, 핑거프린팅에서는 구매자의 정보가 삽입이 된다. 따라서, 핑거프린팅을 이용하면 불법적으로 컨텐츠를 재분배한 구매자가 누구인지 밝혀낼 수 있기 때문에, 구매자들로 하여금 불법적인 재분배하려는 의욕을 저하 시킬 수 있다. 이러한 핑거프린팅 프로토콜 중에서 익명 핑거프린팅 프로토콜은 합법적인 구매자에 대해서는 익명성 을 보장해 주며, 불법적인 재분배자에 대해서만 신원을 밝혀낼 수 있도록 하는 프로토콜이다. 이 논문에서는 현재까지 연구된 익명 핑거프린팅 프로토콜에 대해서 비교 분석하고, 익명 평거프린팅 프로토콜에서 충족되어야 하는 요구사항 들을 살펴본다.

The purpose of the study is to analyze the factors which cause the deviations of e-piracy. For this, empirical data were collected by conducing a field survey with a total of 531 collegians, and a Structural Equation Model was used for the purpose of analyzing the data acquired by that. A Structural Equation Model was designed and constructed by such factors as Anonymous Environment, Norm-Consciousness, and Recognition on Penalty, which are considered as the direct variables. In addition, the factor of Anonymous Environment was set as a variable for the factors of both Norm-Consciouness and Recoginition on Penalty. These are the results of the analysis; it is found that Anonymous Environment is the direct cause of e-piracy, but the other two factors are not statistically significant. And it is also found that Anonymous Environment gives a direct influence on the other factors of Norm-Consciousness and Recognition on Penalty and it also gives indirect influence on the factor of Recognition on Penalty by means of the factor of Norm-Consciousness. Therefore, in order to prevent e-piracy, it is required to provide the proper opportunity to be trained to observe norms under the environment of anonymity. For this, diverse and effectual teaching methods for information ethic education should be sought.
