Drawing on Protection Motivation Theory(PMT), this study attempts to clarify antecedents that influence the intention to protect individuals' privacy on the Internet. Protection motivation forms through individuals' cognitive appeal involving threat and efficacy. Then protection motivation causes privacy behavioral change. Protection motivation factors are established privacy trust and privacy risk, which are related to privacy attitude and belief. This proposed model is empirically analyzed by utilizing structural equation analysis(SEM). According to the result of the empirical analysis, it is founded that almost paths have statistically significant explanatory power except path from efficacy to privacy risk and path from privacy trust to privacy behavioral intention. This study shows powerful evidence of antecedent factors based on protection motivation of individuals' privacy behavioral intention in online environment.

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.

Recently, with the development of deep learning technology, research on recognizing human behavior is in progress. In this paper, a study was conducted to recognize risky behaviors that may occur in a single-person household environment using deep learning technology. Due to the nature of single-person households, personal privacy protection is necessary. In this paper, we recognize human dangerous behavior in privacy protection video with Gaussian blur filters for privacy protection of individuals. The dangerous behavior recognition method uses the YOLOv5 model to detect and preprocess human object from video, and then uses it as an input value for the behavior recognition model to recognize dangerous behavior. The experiments used ResNet3D, I3D, and SlowFast models, and the experimental results show that the SlowFast model achieved the highest accuracy of 95.7% in privacy-protected video. Through this, it is possible to recognize human dangerous behavior in a single-person household environment while protecting individual privacy.

이 글의 목적은 디지털 저작권과 프라이버시 사이의 경합적 요인을 분석하고 균형을 위한 대안을 제시하는데 있다. 현재 대부분의 디지털 저작권 보호기술의 핵심은 사용자를 식별할 수 있는 방법에 있는데, 이러한 사용자 식별은 익명성을 기반으로 하는 프라이버시에 대한 침해요인이 되고 있다. 이와 같은 경합적 요인을 해결하기 위해 익명성을 보장하는 디지털 저작권 관리기술들이 많이 제안되었으나, 그 대부분이 부분적인 문제에 대한 프로토콜의 형태로 이루어진 대안으로, 현재의 인터넷 환경, 사용자의 행동양식, 경제적 요인 등과 부합하지 않는 측면이 많아 적용하기 곤란하다. 한편, 디지털 저작권 보호를 위한 여러 기술적 노력들도 사실상 저작권 보호 효과는 미미한 반면, 사용자의 권리와 프라이버시에 대한 침해요인을 증대시키고 있다. 현재의 상황은 디지털 저작권과 프라이버시의 균형을 위한 기술적 해결이 요원한 상태이다. 이러한 상황에서 균형을 위한 대안으로 법률에 의한 조정과 새로운 비즈니스 모델을 통한 디지털 저작권 보호가 효과적임을 주장하고자 한다. 즉, 기술적 완벽성보다는 사용자 편리성에 의한 실질적인 저작권보호와 법률과 사용자 계도를 통한 프라이버시 보호를 제안한다.

This study investigates the effects of privacy psychological characteristics of B2C logistics services users on their willingness to comply with their logistics companies' information protection policy. Using cognitive valence theory as a theoretical framework, this study proposes a research model to examine the relationships between users' logistics security knowledge, privacy trust, privacy risk, privacy concern, and their willingness of information protection policy compliance. To test the proposed model, we conducted a survey from actual users of logistics services and collected valid 151 samples. We analyzed the data using a structural equation modeling software. The empirical results show that logistics security knowledge positively affects privacy trust; privacy concern positively influences privacy risk; privacy trust, privacy risk, and privacy concern positively influence behavioral willingness of compliance. However, logistics security knowledge does not affect behavioral willingness of compliance. The results of the study provide several contributions to the literature of B2C logistics services domain and managerial implications to logistics services companies.

Due to increased terrors and crimes, the use of surveillance camera systems including CCTV is also increasing. Private information such as faces or behavior patterns can be recorded in CCTV and when it is exposed, it may cause infringement to privacy and crimes. This paper analyses conventional methods on protection of privacy in surveillance camera system and then suggests an RFID-based surveillance camera system that can both watch crimes and protect privacy. The proposed system protects privacy and watches crimes using scrambling and an RFID system.

As the privacy issues are all around the world, the intrusion into personal privacy is concerning. For that reason, government established the article from the personal information protection law that has to notice the privacy policy to users on the online site. and the matter of privacy invasion make concern toward behavior of online user. Although there are rules to carrying legal binding force in accordance with, because it is full of text and uncomfortable to read so that its readability is low. In the same context, each other has different state of understanding with the policy for personal information has been playing an important role. In this approach, companies and government do not think this over deeply and do just for what their practical use is. That is the reason why this research start, and the result expecting for real. As the result in the participant who cognize the privacy policy display pattern, they have certain type to do. In this article, the certain behavior doing is remarkable with the privacy policy. According to privacy concern, privacy fundamentalist reveals such a compromise reaction to protect their information when they know what information which the privacy manager of service provider collect. This study arrives at the result depending on the gap of privacy group that the group of checking the policy contents, especially the group which has high privacy concern, they move forward to protect their emotion and put a constructive plan into protective action. Otherwise, the group of unchecking the policy contents and following their own thinking of privacy policy are not deemed statistically significant. Therefore, this is considered to support more various implications than the previous issues and alternatives about privacy policy pattern and user protection behavior of privacy.

The present study was carried out with a view to examine the protective actions of physical and occupational therapists for patients's privacy. For this purpose, a survey was conducted with the questionnaires that were distributed to 297 physical and occupational therapists engaged in general hospitals as well as in rehabilitation clinics across the country from January 2 to 13, 2012. From the survey, it was made known that the overall extent of protective actions practiced by them was $3.54{\pm}.733$ in average. Divided by area, the average protective action in communication was $3.62{\pm}.776$, followed by $3.57{\pm}1.013$ in direct contact and $3.53{\pm}.780$ in maintenance and management, respectively. The analysis of general characteristics by each area showed that the older their age gets and the longer their career is, the more the protective action is practiced by them. Although they are well aware of the fact that the medical information of patients should be kept 100% secret and they practice it to almost excellent grade (5), the physical and occupational therapists, as key experts in charge of improving functions of patients, were found to have little concern for and little knowledge about contents of protecting medical information. It is thus required to perform public relation and instruction continuously to intensify their awareness of needs to protect patients' privacy and to implant ethical sense in this regard deep in their mind.
