As our society is changed to the information & digital society based on the internet, the requirement that the analog certificate of Korean residence is changed to digital one is increased. The Korean Government selected the smart card of 72 KB for the digital certificate of Korean residence and try to insert the personnel information of 41 items to it. The method that the numerous personnel information is stored in one smart card is convenience to use. If the certificate of residence is lost, the number of personnel information is misused or spreaded thorough the Internet by the hacking. In this paper, we analyze the problem about the digital certificate of Korean residence and propose the countermeasure about the problem. In the proposal, the digital certificate of residence have only the certificate. Therefore, the size of the smart card is minimized and can be canceled at the loss of the certificate of residence.

Growing importance of online security on certification, many of the web-related security technology introduced day by day. Especially, using smart certificate (USIM) is recognized as one of the most safe and convenient method for the security of public certificate. The purpose of this study is to find the factors that affect the Intention of switching to smart certificate for the general public who use public certificate service. Based on migration theory, this study determined the relationship between pull factors, push factors and mooring factors which can affect the intention of switching to smart certificate. To empirically analyze the proposed hypothesis, the statistical analysis were conducted based on the response from 350 public certificate service users using SPSS 22.0 and Smart PLS 2.0. The results of this study can be summarized as follows. First, system quality, one of the pull factors has positive influence on perceived ease of use. On the other hand, the other pull factor, service quality has positive influence on both perceived ease of use and perceived usefulness. Second, push factors, user experience and information security awareness have positive influence on perceived ease of use only. Third, mooring factor, switching cost does not have influence on switching intention while perceived usefulness has positive influence on. The results of this research can be used for whom has interest to the switching intention of public certificate service for online security and provide the proper understanding about smart certificate service mechanism.

According to 'The Analysis of Industrial Accidents in 2016' by Ministry of Employment and Labor, the number of deaths caused by accidents in the construction field is 391, accounting for 47% of 826 industrial fatalities in all industries. The breakdown of the 391 fatalities of the construction industry shows that 'struck by an object' accident had 30 fatalities, the 3rd in frequency following falling (235) and crashing (32) accidents. This study aims to explore ways to reduce the 'struck by an object' accident with emphasis on safety education and certificate system for rigging and slinging works. This study reviews literature on rigging and slinging works and analyzes 'struck by an object' accidents. The rules and regulation on the rigging and slinging works are also reviewed both for Korea and other countries with best practices in construction safety such as Singapore, Japan, U.K., and U.S. The rigging and slinging certificate systems of those countries are also reviewed to find any advantage in the construction safety management. In addition, a pilot rigging and slinging certificate system was executed in one of domestic construction site followed by two surveys: one on the riggers who participated in the pilot operation and the other on general managers in domestic construction sites. Based on the analysis of the 'struck by an object' accidents and pilot operation, this study proposes a rigging and slinging certificate system to reduce accidents, enhancing safety condition of construction sites. The certificate system was proposed in a way to accommodate working practice of construction sites. Depending on rigging careers and a crane load capacity, riggers are eligible to apply either basic or master certificate which makes difference in the level of rigging works. The safety condition of rigging and slinging work could be substantially enhanced if workers, managers, supervisors, administrators, and policy makers work together consistently.

The notion of a certificate was introduced by Kohnfelder in his 1978 MIT bachelor's thesis. The idea, now common, was that a certificate is a digitally signed statement binding the key-holder's name to a public key. With the increasing acceptance of digital certificate, there has been a gaining impetus for methods to nullify the compromised digital certificates and enable the end user to receive this information before be trusts a revoked certificate. The problem of certificate revocation is getting more and more crucial with the development of wide spread PKIs. In this paper, we investigate recent trend of certificate revocation mechanism.

In this paper, we review digital certificate technologies and their applications in e-commerce. Current digital certificate technologies are evaluated and their importance is explained. The configuration of certificate flows from providers to users through software, hardware, and network technologies is described. These five domains and the configuration of digital certificate flows guide our review of the characteristics of digital certificates. We then develop a framework for the classification of digital certificates that integrate these five domains with VeriSign's types and levels of assurance. In order to demonstrate the adequacy of our digital certificate classification framework, we populated it with VeriSign's digital certificates. Within each domain, VeriSign's classes of digital certificates are classified in accordance with the VeriSign type and level of assurance. The results of our analysis suggest that the framework is a useful step in developing a taxonomy of digital certificate technologies. The strengths and weaknesses of the study are discussed, and opportunities for further research are identified and discussed.
