Currently mobile messenger industry, based on mobile application, is growing. And it has aroused innovative change, offering services in various forms beyond the form simply sharing messengers. Also because messenger securities are becoming personalized and intelligent, the importance of more diverse mobile applications' securities is increasing. This study carries out the empirical study of the causal relationship that the factors of using application services influence on security recognition and security Intention of mobile securities, and consequentially impact upon protection of personal information of users. In order that, we present the research model which prime variables of SDT, which emphasized on natural immanent motivation of human, applied to. To verify the research model of this study empirically, we conducted a survey targeting the public and university students which have ever used mobile messenger applications. With this, we desire to contribute to emphasizing the significance of individual messenger security and playing a positive role to develop security guide for consumers. The path analysis results are as follows. First, perceived autonomy has a positive effect on both security awareness and security intention. Second, perceived competence has a positive effect on security intention. Third, perceived relatedness has a positive effect on both security awareness and security intention. Last, security awareness and security intention. have a positive effect on privacy protection behavior. Through emphasizing the importance of the security of the messenger of individuals and contribute to a positive role for development of the necessary security guidelines to consumers.

This paper deals with the online privacy policy, which is designed to solve the information asymmetry problem between websites and internet users. We empirically analyze the recognition, confirmation of the online privacy policy, and its effects on online transaction behavior using a rich survey data representing 5,422 Korean internet users. Major results are as follows. First, there exists a significant difference between recognition and confirmation, and confirmation behavior is positively related with the importance of privacy issue and the experience of privacy invasion. Second, binary variable regressions show that internet user tends to participate in online transaction if he/she confirms the online privacy policy positively. Finally, if websites would make online privacy policy easy and short, a yearly online transaction market size of Korea would increase by 0.46 million participants and 22.4 billion KRW.

Since 2008, large-scale personal information breach incidents have occurred frequently. Even though national education, policy, and laws have been enacted and implemented to resolve the issue, personal information breaches still occur. Currently, individuals cannot confirm detailed information about what personal information has been affected, and they cannot respond to the breaches. Therefore, it is desirable to develop various methods for preventing and responding to personal information infringement caused by breach and leakage incidents and move to privacy protection behaviors. The purpose of this study is to create understanding of personal information security and information breach, to present services that can prevent breaches of personal information, to investigate the necessity of and analyze the potential public demand for such services, and to provide direction for future privacy-related information services.

Courier services users' experience of violating privacy affects psychology and behavior of protecting personal privacy. Depending on what privacy infringement experience (PIE) of courier services users, learning about perceived privacy infringement incidents is made, recognition is formed, affection is formed, and behavior is appeared. This paradigm of changing in privacy psychologies of courier services users has an important impact on predicting responses of privacy protective action (PPA). In this study, a theoretical research framework are developed to explain the privacy protective action (PPA) of courier services users by applying attitude theory. Based on this framework, the relationships among past privacy infringement experience (PIE), perceived privacy risk (PPR), privacy concerns (i.e., concerns in unlicensed secondary use (CIUSU), concerns in information error (CIE), concerns in improper access (CIA), and concern in information collection (CIC), and privacy protective action (PPA) are analyzed. In this study, the proposed research model was surveyed by people with experience in using courier services and was analyzed for finding relationships among research variables using structured an equation modeling software, SMART-PLS. The empirical results show the causal relationships among PIE, PPR, privacy concerns (CIUSU, CIE, CIA, and CIC), and PPA. The results of this study provide useful theoretical implications for privacy management research in courier services, and practical implications for the development of courier services business model.

우리는 언제부터인가 개인용 컴퓨터에 개인정보와 같은 민감한 데이터를 사용자의 동의 없이 수집하거나 성가시게 혹은 불쾌한 광고를 출력하는 프로그램들로 가득차 있는 것을 자주 경험하고 있다. 이러한 모든 행동들은 사용자의 적절한 동의 절차 없이 이루어졌다는 것이 가장 근본적인 문제이고 바로 여기서부터 문제를 해결해 나가야할 것이다. 그러나 법적으로 스파이웨어(Spyware)가 명확히 정의되어 있지 않고 그나마 (구)정보통신부에서 발표한 문건은 하루가 멀다 하고 새롭게 변화하는 스파이웨어들에 법적인 구속력을 적용하기 힘든 것이 현실이다. 이 글에서는 현재 국 내외에서 스파이웨어가 어떻게 정의되고 있는지 알아보고 스파이웨어를 정의하기 위해 필요한 기술적인 배경을 살펴봄으로써 보다 효율적인 법안을 마련하는 데 도움이 되고자 한다.

This paper describes how to protect the personal information of a biometric reference provider wherein biometric reference and personally identifiable information are bounded in a biometric system. To overcome the shortcomings of the simple personal authentication method using a password, such as identify theft, a biometric system that utilizes physical and behavioral characteristics of each person is usually adopted. In the biometric system, the biometric information itself is personal information, and it can be used as an unique identifier that can identify a particular individual when combining with the other information. As a result, secure protection methods are required for generating, storing, and transmitting biometric information. Considering these issues, this paper proposes a method for ensuring confidentiality and integrity in storing and transferring personally identifiable information that is used in conjunction with biometric information, by extending the related X9.84 standard. This paper also outlines the usefulness of the proposition by defining a standard format represented by ASN.1, and implementing it.

Biometric recognition refers to a technology that identifies or verifies an individual after registering each individual's physical, physiological, and behavioral characteristics with an automated device. However, the biometric data used here corresponds to personal information since it can identify an individual. Therefore, when it is compromised or misused, it negatively affects the privacy of the data subject. In this paper, we review the current status of domestic laws related to biometric information and the status of infringements related to this. And then, some biometric application models are derived and vulnerabilities and countermeasures for each model are discussed. Finally, for the developer and service provider of the biometric system, protection guidance is presented.

최근 들어 인터넷사업자들이 웹상에서 제공하는 새로운 서비스가 각국의 개인정보보호 법제에 저촉되는 사례가 늘고 있다 인터넷사업자들이 국경을 넘어 정보를 수집하고 이를 가공처리, 저장하는 과정에서 본인의 동의를 얻지 않거나 개인정보를 익명처리하지 않은 것이 주로 문제가 되고 있다. 본고는 국제적으로 서비스를 하고 있는 대형 인터넷사업자가 프라이버시 침해 혐의를 받고 있는 사례를 알아보고, 무엇이 문제가 되는지 쟁점을 검토하였다. 특히 현지 감독당국이 글로벌 인터넷사업자의 위법사실을 적발하였더라도 해당 사업자가 대리인이나 분신 도구를 통하여 행동한 사실이 없으면 본사에 제게를 가할 수 없는 실정이다. 사이버공간에서는 실제 위반행위자가 없더라도 중대한 개인정보를 침해하는 결과를 가져온다면 영화 <아바타>에서와 같은 해결방법을 모색해볼 수 있다. 아바타는 독자적인 사고나 판단능력이 전혀 없지만, 나비족이 사는 낙원이 지구인에 의하여 파괴될 수 있는 상황에서 아바타와 이를 조종하는 사람들이 한 몸이 되어 나비족과 힘을 합쳐 아름다운 낙원을 지켜낸다. 즉, 인터넷사업자가 국내 실재하지 않더라도 그의 활동결과로 볼 수 있는 침해행위가 발생하고, 그 결과 회복할 수 없는 피해가 발생할 우려가 있으며, 본인과 아바타를 한 몸으로 볼 수 있다면 아바타를 통해 위법행위를 저지른 본사의 책임자를 처벌할 수 있어야 한다. 만일 그 책임자를 특정할 수 없더라도 그의 감독책임이 있는 본사 법인에 책임을 물을 수 있다고 본다. 만일 법원에서 이러한 '아바타 이론'을 수용한다면 국내에서도 외국 본사에 벌금을 과하는 등 처벌이 가능할 것이다. 다만, 해당 인터넷사업자의 반발도 만만치 않을 것이므로 주요국 개인정보 감독기구는 수사정보를 교환하는 등 국제적으로 긴밀한 협조체제를 갖출 필요가 있다.

As the effective use and strong protection of an organization's information resources are recognized as a condition for the growth of an organization, they are increasing technological and policy investments in IS(information security). However, information exposure can occur from external invasions such as hacking and incidents related to misuse and abuse by insiders. This study proposes a mechanism that considers the organizational environment and individual characteristics from the viewpoint of promoting employees' IS participation activities. In other words, the study presents the complex effects of organizational environmental factors (ethical leadership, IS collaborative communication) and personal factors (person-organization fit) on organization trust and IS voice behavior. We surveyed office workers who asked for IS-related business activities and tested hypotheses using 422 samples. As a result, ethical leadership influenced organization trust through collaborative communication, and organization trust strengthened IS voice behavior by having an interaction effect with person-organization fit. This study suggests direction for establishing an organizational environment for promoting IS-related activities by office workers, so it provides practical implications for organizations with goals related to internal information exposure control.
