생체정보를 이용한 사용자 인증은 차세대 인증 방법으로서 기존의 인증 시스템에서 급진적으로 사용되고 있는 인증 방법이다. 현재 대부분의 생체인증 시스템은 단일 생체정보를 이용하고 있는데, 단일 생체인증 시스템은 노이즈로 인한 문제, 데이터의 질에 대한 문제, 인식률의 한계 등 많은 문제점들을 가지고 있다. 이를 해결하기 위한 방법으로 다중 생체정보를 이용하는 사용자 인증 방법이 있다. 다중 생체인증 시스템은 각각의 정보에 대한 information fusion을 적용하여 새로운 정보를 생성한 뒤, 그 정보를 기반으로 사용자를 인증한다. information fusion 방법들 중에서도 Rank-level fusion 방법은 표준화 작업이 필요하고 높은 계산 복잡도를 갖는 Score-level fusion방법의 대안으로 선택되고 있다. 따라서 본 논문에서는 기존 방법보다 정확도가 높게 향상된 Rank-level fusion 방법을 제안한다. 또한, 본 논문에서 제안하는 방법은 낮은 정확도를 갖는 matcher를 사용하더라도 정확도를 향상시킬 수 있음을 실험을 통해 보이고자 한다.

In recent years The importance of information security management for securing information collection and analysis, production and distribution is increasing. Companies are assured of confidence in information security through authentication of information Security Management System. However, level assessment and use of domains that make up the management system is limited. On the other hand, the security maturity model is able to diagnose the level of information protection of the enterprise step by step. It is also possible to judge the area to be improved urgently. It is a tool to support goal setting according to the characteristics and level of company. In this paper, C2M2, which is an example of security maturity model, is compared and analyzed with Korea Information Security Management System certification. Benchmark the model to check the level of information security management and derive the priority among the items that constitute the detailed area of information security measures of ISMS certification. It also look at ways to check the level of information security management step by step.

The effectiveness of informatization can vary depending on the level of operation of the information system as well as investment and installation. This study investigates and analyzes the information system operating environment and quality level of small and medium-sized manufacturing companies in Korea, and investigates how it affects the performance indicators of companies. The influence of the environmental factors operating the information system on the productivity performance and financial performance through the quality level of the information system was analyzed through the structural model. As a result of the analysis, it can be said that the higher the level of information system operating environment factors, the higher the quality level, the higher the quality level, the higher the productivity performance, and the higher the productivity performance, the higher the financial performance. It is judged that the effect of informatization depends on the operating environment and quality level after the installation of the information system.

The purpose of this paper is to examine the moderate effects of self monitoring and the ways of thinking on the relationships and the moderate effects of brand credibility and brand attachment on the relationships between the negative information about a brand and the customer attitude holistic and analytic on the relationships between the negative information about a brand and customer attitude. To accomplish these purposes, this research divided negative information about a brand into corporate ability and corporate social responsibility. In addition, research also divided product type into functional product and symbolic product. participants are classified as having Low or High self monitoring. and the ways of thinking divided into holistic and analytic on the relationships between the negative information about a brand and customer attitude. The following are the summary of hypothesis test: (1)the consumers with low(high) level of self monitering are more likely to reveal high level of preference for negative information of corporate ability. (2)the consumers with analytic(holistic) ways of thinking are more likely to reveal high level of preference for negative information of corporate ability. (3)the consumers with low(high) level of self monitering are more likely to reveal high level of preference for functional product. (4)the consumers with analytic(holistic) ways of thinking aren't more likely to reveal high level of preference for functional(symbolic) product.

In this research the levels of information infrastructure of selected forwarders were measured and analyzed a relationship with business performance. The selected forwarder was consisted of local forwarder group and foreign invested forwarder group. In this analysis the level of information infrastructure of foreign invested forwarder group was higher than local forwarder group, and accordingly their performance was found a difference. i. e. A positive significant relationship was found between the level of information infrastructure and forwarders' business performance by means of correlation analysis.

Based on the Construal Level Theory, this study aims to investigate how information security vaccine users' selection intentions differ from each other according to the selection time of information security vaccine, advertisement message types, and information security knowledge levels. For the foregoing, this study conducted an experiment by applying an experimental design of 2(knowledge level: high/low) ${\times}2$(temporal distances: short distance/long distance) ${\times}2$(advertisement message types: how(concrete)/why(abstract)) on computer security vaccine softwares. As a result, this study confirmed that the selection intentions about information security vaccines differed from each other according to the temporal distance and advertisement message type, and also varied according to the information security knowledge level. In conclusion, this study provides an implication that the consideration of well-timed persuasive message is especially important for the users at the high level of knowledge. Also, this research implies the necessity of development of abstract thinking ability based on temporal distance for the users at the low level of knowledge.

The SSE-CMM model is how to verify the level of information protection as a process-centric information security products, systems and services to develop the ability to assess the organization's development. The CMM is a model for software developers the ability to assess the development of the entire organization, improving the model's maturity level measuring. However, this method of security engineering process improvement and the ability to asses s the individual rather than organizational level to evaluate the ability of the processes are stopped. In this research project based on their existing research information from the technical point of view is to define the maturity level of protection. How to diagnose an information security vulnerabilities, technical security system, verification, and implementation of technical security shall consist of diagnostic status. The proposed methodology, the scope of the work place and the current state of information systems at the level of vulnerability, status, information protection are implemented to assess the level of satisfaction and function. It is possible that measures to improve information security evaluation based on established reference model as a basis for improving information security by utilizing leverage.

The purpose of this study was to present implications for empirical analysis of the structural relationship between the level of activities for senior citizens, self-efficacy, and life satisfaction and depression. In order to the survey was conducted For the elderly students who are enrolled in the Senior Citizens' Welfare Center and participating in the information service education in the G-metropolitan city. The method of data analysis was verified by the Regression and Hierarchical Regression analysis using the spss 22.0 statistical program. As a result, The level of activity for the elderly increases the level of self-efficac, The level of activity and self-efficacy of the elderly increased the level of living satisfaction of the elderly and It has been shown to lower the level of depression. Self-efficacy has been shown to have a mediating effect in the relationship between senior citizens' level of information service activities and living satisfaction and depression. Based on these analysis results, a policy measure was proposed to enhance the level of activities for senior citizens.
