We present a new multimodal biometric authentication method, which performs both feature-level fusion and decision-level fusion. After generating support vector machines for new features made by integrating face and voice features, the final decision for authentication is made by integrating decisions of face SVM classifier, voice SVM classifier and integrated features SVM clssifier. We justify our proposal by comparing our method with traditional one by experiments with XM2VTS multimodal database. The experiments show that our multilevel fusion algorithm gives higher recognition rate than the existing schemes.

"The certification of compliance of new products of industrial convergence" (hereinafter referred to as "certification of compliance") is a legal certification system in accordance with the Industrial Convergence Promotion Act through which a convergence new product can be officially certified without legislation when the certification standards applicable to the product are not yet provided. Unlike other certification systems, the certification of compliance is characterized by the role of resolving the certification difficulties driven by the regulatory lag of convergence new products. Nevertheless, studies that analyzed the certification of compliance in detail from the viewpoint of regulatory improvement were surprisingly rare. Through the sequential matching of the steps of certification of compliance with the process from the occurrence of a regulatory problem to resolution, our study provided clear understanding as to how the regulatory lag could be reduced by the procedure for certification of compliance. Furthermore, we divided the perspective on regulatory lag management into quantitative and qualitative, and the structures and practices of certification of compliance were then analyzed from the two perspectives. By doing this, the present study emphasized that the fundamental reason the certification of compliance could effectively solve the regulatory lag problem of convergence new products was not only the quantitative elements such as legal deadlines for each step but also several qualitative approaches to securing the quality of every stage.

In a society where ICT technology is converged, the use of various network-connected devices such as IoT is spreading. Network-connected devices are inevitably exposed to the threat of hacking such as information leakage, and countermeasures need to be prepared to respond. Security certification system for IoT devices has been introduced to promote security of IoT products, and for this purpose, legalization and standardization of certification standards and methods are in progress. In line with this, in Korea, as the Information and Communication Network Act was revised in 2020, ICT convergence devices connected to the network were newly defined as "information and communication network connected devices," and the basis for the security certification system is being established. We summarized related domestic and foreign trends and suggest specific considerations for implementing the security certification system for IoT devices in South Korea.

The purpose of this study is to investigate engineering students' attitude toward convergence and relevance with engineering education accreditation, gender, and academic year and attitude toward convergence. To be specific, fist, we examined whether the instrument for measuring attitudes toward convergence were reliable and valid for engineering students. Second, we compared levels of attitudes toward convergence in terms of engineering education accreditation, gender and academic year. Third, latent classes, which were distinguished in terms of attitudes toward convergence, were identified. Participants were 2076 engineering students. By using factor analysis and Rasch analysis, validity and reliability of instrument measuring attitudes toward convergence were confirmed. The differences in attitude toward convergence in terms of engineering education accreditation experience, gender, and academic year were examined by independent t-test and ANOVA. There were significant differences in attitude towards convergence in terms of engineering education accreditation, gender, and academic year. Students who experience engineering education accreditation program and male and high academic year have higher levels of attitude toward convergence than others. Lastly latent class analysis (LCA) was conducted to identify subgroups underlying engineering students in terms of attitude toward convergence and five latent classes were identified. In addition, the chi-square results showed that there were significant relationships between identified latent classes and engineering education accreditation, gender, and academic year. Based on these results, engineering education considering students' characteristics and diversity in attitude toward convergence were discussed.

The convergence of traditional industry and ICT is a combination of security threats and vulnerabilities in ICT and specific industry-specific problems of existing industries, and new security threats and vulnerabilities are emerging. In particular, in the medical ICT convergence industry, various problems regarding user authentication are derived from the medical information system, which is being used for abuse and security weaknesses. According, this study designed and implemented a user authentication system for secure user management in medical ICT convergence environment. Specifically, we design and implement measures to solve the abuse and security weaknesses of ID sharing and to solve the inconvenience of individual ID / PW authentication by performing user authentication using personalized devices based on medical information systems.

보안은 5G 이동통신 네트워크의 성공적인 정착을 위한 필요충분조건이다. 5G 보안의 중요한 표준으로 3GPP (3rd Generation Partnership Project)의 보안 담당 워킹그룹인 SA3는 3GPP 5G 보안구조를 제시하였다. 특히, 3GPP 5G 보안구조는 Extensible Authentication Protocol (EAP) 인증 프레임워크를 채택함으로써 이기종의 다양한 인증 기법과 자격증명을 용이하게 포용할 수 있는 유연성을 갖추었다. 서비스 융합 네트워크를 지향하는 5G의 비전을 고려할 때, EAP 인증 프레임워크는 보안측면에 있어서 매우 중요한 전략이라고 볼 수 있다. 따라서, 본 논문에서는 3GPP 5G 보안구조를 위한 EAP 인증 프레임워크를 고찰한다. 이를 위해, 1차 인증을 위한 EAP 기반의 인증 프로토콜 EAP-AKA'을 면밀히 검토하면서 1차 인증에서의 EAP 인증 프레임워크 적용방안을 분석한다. 아울러, 2차 인증을 위한 EAP 인증 프레임워크의 적용과 네트워크 슬라이싱 (Network Slicing)과의 연동을 살펴본다.

From the viewpoint of fire-fighting activities, public building have structural and management problems in fire, so evacuation disturbance and risk of expanding combustion are high. As a result of analyzing various fire fragile factors of public building, The evaluation areas were derived from safety systems, fire-fighting facility, structure safety, general safety and the evaluation factors were presented. Also, the characteristics of domestic and foreign certification systems were analyzed by comparing and analyzing the status of fire safety performance certification system for 6 domestic and overseas apartment houses. In conclusion, the 5 convergence directions of certification system and 22 evaluation items by 4 evaluation fields were derived, and based on this, we have established 3 convergence introduction plans of fire safety performance certification system of public building.

최근 편리하고 안전한 생체인증 기술이 핀테크 서비스의 필수 구성요소가 되고 있다. 그러나 생체인증의 보안성과 정확도 향상을 위해 많은 양의 생체 정보를 활용한다면 연산과정이 복잡해져서 속도 저하와 개인정보 유출 가능성이 높아지고, 실시간성을 제공하기 위해 생체 정보의 일부만 샘플링하여 활용하는 경우에는 보안성과 정확도가 열화되는 Trade-off 문제가 있다. 종래의 생체인증 기술은 메타데이터를 이용한 필터링의 경우 데이터 간의 상관성이 고려하지 않아서 개인정보보호와 사용자 편의성에 한계가 있었다. 본 연구에서는 상관성 높은 데이터를 활용하여 프라이버시 중심의 생체인증 설계와 보안사용성을 향상시키는 방안을 제안한다.

Encryption and authentication system in National Defense is divided into three system; KMI, MPKI, and GPKI. In this paper, we report inherent problem and security threaten in MPKI and propose an attribute-based authentication scheme using attribute-based signature in order to improve user authentication. In our scheme, access structure is used by Monotone Span Program, and system server provides service after user authentication.
