최근 개인정보보호법 제정으로 온라인 회원등록시 본인확인과정에 주민등록번호를 사용하지 않는 방안이 필요한 상황이다. 대부분의 웹사이트는 주민등록번호를 사용하지 않는 신원확인 방안으로 아이핀(i-PIN)을 사용하고 있다. 하지만, 아이핀의 경우 고정된 정보(아이디, 패스워드) 값만 탈취하면 개인정보유출의 위험이 있다. 본 논문에서는 OTP를 이용하여 비연결성을 보장하는 신원 확인할 수 있는 방안을 제안한다. 제안된 방식은 웹사이트 회원가입시 아이디, 패스워드 같이 일관된 정보를 사용하지 않고, 웹사이트마다 각기 다른 정보로 회원가입을 하기 때문에 개인정보보호에 활용 가치가 높을 것이다.

본 논문에서는 물체의 3차원 모델을 복원하기 위하여 거리영상 카메라에서 획득한 다시점 3차원 거리영상을 온라인으로 정합(registration)하는 기술을 제안한다. 3차원 모델 복원을 위하여 거리영상 카메라를 복원하고자하는 물체 주위로 이동하여 연속된 다시점 거리영상과 사진영상을 획득하고 물체와 배경을 분리한다. 분리된 다시점 거리영상의 정합을 위하여 이미 등록된 거리영상의 변환정보 그리고 두 거리영상 사이의 기하정보를 이용하여 정합을 초기화한다. 위 과정을 통해 서로 인접한 거리영상에서 영상 특징점을 선택하고 특징점에 해당하는 거리영상의 3차원 점군을 이용하여 투영 기반(projection-based) 정합을 실시한다. 기하정합이 완료되면 사진영상 간의 대응점을 추적하여 정합을 정제(refinement)하는 과정을 거치는데 KLT (Kanade-Lucas-Tomasi) 추적기를 수정하여 대응점 탐색의 속도와 성공률을 증가시켰다. 영상 특징점과 추적된 대응점에 해당하는 3차원 점군을 이용하여 거리영상을 정제하였다. 정합과 정제의 결과를 통해 추정된 변환 행렬과 정합된 대응점들 사이의 거리를 계산하여 정합 결과를 검증하고 거리영상의 사용 여부를 결정한다. 만약 정합이 실패하더라도 경우에도 거리영상을 실시간으로 계속 획득하고 정합을 다시 시도한다. 위와 같은 과정을 반복하여 충분한 거리 영상을 획득하고 정합이 완료되면 오프라인에서 3차원 모델을 합성하였다. 실험 결과들을 통해 제안한 방법이 3차원 모델을 성공적으로 복원할 수 있음을 확인 할 수 있었고 오차 분석을 통해 모델 복원의 정확도를 검증하였다.

Choi et al's work [1] in 2015 demonstrated that the resident registration numbers (RRNs) of individuals could be conveniently estimated through their personal information that is ordinarily disclosed in social network services. As a follow-up to the study, we introduce the status of the RRN system in Korea in terms of its use in the online environment, particularly focusing on their secure use. We demonstrate that it is still vulnerable against a straightforward attack. We establish that we can determine the RRNs of the current president Moon Jae-In and the world-class singer PSY.

본 연구는 반려견을 양육하는 소비자를 대상으로 동물등록제에 대한 인식을 구체적으로 확인하고, 반려견에 대한 애착양상에 따라 동물등록제에 대한 인식이나 선호가 달라지는지를 분석하였다. 온라인 설문조사를 통해 250부의 자료를 수집하였고, SPSS 24.0을 이용하여 분석을 실시하였다. 연구결과, 소비자가 반려견과의 관계에서 형성하는 애착의 형태는 동반자적 애착과 정서교감 애착으로 확인되었다. 반려견에 대한 애착양상에 따라 소비자는 단순동거형(25.6%), 친밀동반형(30.4%), 강한유대형(44.0%)의 3개 유형으로 분류되었다. 소비자 유형별로 동물등록제 인지여부 및 등록여부와의 관계에서 통계적으로 유의한 차이가 있었다. 그리고 소비자 유형에 따라 동물등록제에 대한 인식 및 선호도에 있어 통계적으로 유의한 차이가 나타났다. 본 연구는 실효성 있는 동물등록제 개선 방안에 대한 소비자의 인식 및 선호를 실증하여 소비자 지향적인 동물등록제 발전 방향을 제언한다는 점에서 의의를 가진다.

Currently, online means of replacing resident registration numbers(RRN) include I-Pin, mobile phone, credit card, MyPin, and general-purpose certificate. In order to issue alternative means based on the RRN, it must be designated through the designation review by the Korea Communications Commission(KCC) through a designation review by personal proofing agency and be subject to annual management. However, the criteria for designation and follow-up of the designation of the personal proofing agency carried out by KCC have been used in 2010 without revision, and there are problems that do not conform to the evaluation standards of various alternative means. Therefore, in this paper, we propose a method for improving the designation criteria and management system of the personal proofing service agency. The proposed method analyzes the characteristics of the alternative identification-based personal proofing service and proposes a follow-up management standard that can appropriately evaluate the analyzed characteristics and improves the designation criteria according to the emergence of new alternatives. Through the proposed method, it can be seen that it is possible to strengthen the safety of the personal proofing service based on the alternative means of RRN provided online and face-to-face and to protect the user's personal information.

With the deployment of web-based educational game over the internet, the user's registration becomes a critical element. The user is authenticated by the system using username, password, and unique code. However, it cannot be handled properly because the data is transmitted through insecure channel on the network. Hence, security requirement is needed to avoid identity leakage from malicious user. In this paper, we propose a secure communication approach using SSL protocol for an online game. We also describe the security requirements for our approach. In future work, we intend to configure and implement the SSL protocol by enabling HTTPS in web-based online game.

This paper proposes a method to protect the copyright of creators' content shared through an online sharing platform in a legal battle. When creators upload their independent creation content to the online sharing platform, it automatically upload information necessary for copyright effect to this system. The data warehouse of this system is as a private blockchain for to ensure non-repudiation and transparency of the information. We present that the data warehouse is to build as Hyperledger Fabric in this paper. And We present the transaction data structure of the blockchain to prevent orphan works. We also dealt with how to build a website where users can conveniently check the data (copyright related information) of this blockchain.

Due to the expansion of non-face-to-face services, the demand for user identification for mobile devices is increasing. Recently, mobile resident registration cards, mobile driver's licenses, etc. are installed in mobile phones and used for user identification and authentication services. In order to identify a user online, unique identification information of the online user is required. In particular, in order to provide information only to online users, it is necessary to accurately deliver information to a mobile device owned by the user. To make this service possible, it was realized with the advent of mobile electronic notice service. However, the identification of online service users and information on mobile devices owned or subscribed by the relevant users require safe management as personal information, and it is also necessary to increase the convenience of online service users. In this paper, we propose an operating standard for providing a mobile electronic notice service that sends electronic notice using a mobile device owned by the user. The mobile electronic notice service is a service that provides notices expressed in electronic information to the recipient's cell phone, mobile app, e-mail, etc. Therefore, as the use of mobile electronic notification service increases and the provision and use of connecting information to identify users increases, it is necessary to expand the mobile electronic notification service while safely protecting users' personal information.

Purpose: This study was conducted on dental technicians to examine the problems of the dental laboratory registration system and devise a plan to improve it. Methods: For data collection, an online survey was conducted on 14,015 dental technicians registered in the Korea Dental Technologist Association as of October 2020. Among the collected 405 questionnaires, 391 data were used for analysis. Results: We found that dental technicians felt that the dental laboratory opening registration system was unfair. There were problems including the problem of the verification method of job performance, not acknowledging the difference in the job field, and the lack of understanding of the structure of work cooperation between dentistry and dental laboratories. Furthermore, it was recognized that the system was improved by reflecting the change in job area according to the change of the times. Conclusion: There is an urgent need to reorganize the legal system so that the dental technicians can have their professionalism and autonomy recognized while remaining faithful to the public interest of protecting the national oral health by revising the related regulations, thereby ensuring smooth work activities.

Recently, there is the trend that online and reuse have been focused via digitalization of information and business process that individuals, government and firms own. This study, by designing and implementing a system, has the aim to provide on-line information about the classes and related classes to students on real time. Furthermore, with this system, the students can easily search the necessary class information and understand the curriculum structure. Thus he or she can make a decision about classes and moreover his and her career development. Also this system has been designed to be managed with ease and has more expandibility. Thus this is expected to affect the effort of universities and research centers that the online systems and digital contents have been more applied in order to adapt toward rapidly changing education environment.
