Recently by the privacy & data security law, when a user registers the online membership, we need to take action to check a progress of identification without resident registration number. On the most of websites, I-PIN is used by identification instead of the resident registration number. However, I-PIN causes dangerous situations if someone steals the ID and a password, the personal data can be easy to exposure. In this paper, we propose the OTP, which can solve all these problems by guaranteeing the identification of unlinkability. This type of method would help the process of membership registration without fixed data like ID and a password in online so it would be very useful to security of private data.

An on-line registration technique is presented to register multi-view range images for the 3D reconstruction of real objects. Using a range camera, we first acquire range images and photometric images continuously. In the range images, we divide object and background regions using a predefined threshold value. For the coarse registration of the range images, the centroid of the images are used. After refining the registration of range images using a projection-based technique, we use a modified KLT(Kanade-Lucas-Tomasi) tracker to match photometric features in the object images. Using the modified KLT tracker, we can track image features fast and accurately. If a range image fails to register, we acquire new range images and try to register them continuously until the registration process resumes. After enough range images are registered, they are integrated into a 3D model in offline step. Experimental results and error analysis show that the proposed method can be used to reconstruct 3D model very fast and accurately.

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.

The aim of this study was to identify the awareness of the animal registration system, as well as to determine if there is a difference according to the types of pet attachment of consumers raising companion dogs. For this purpose, 250 data were collected by conducting an online survey and analyzed the data using SPSS 24.0. As a result of the study, pet attachment was identified as a companion attachment and emotional attachment. According to the form of attachment to dogs, the consumer types were categorized into three groups: type of simple cohabitation(25.6%), type of close companion(30.4%), and type of strong bond(44.0%). It was found that there are statistically significant differences in the relationship between the recognition and registration of the animal registration system for each consumer type. In addition, there were statistically significant differences in the perception and preference of the animal registration system depending on the type of consumer. This study has significance in that it suggests the effective direction of developing the consumer-oriented animal registration system.

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.
