After the launch of smart phones, various miniaturized smart devices such as wearable and IOT devices have deeply embedded in human life, and have created a technology-oriented society. In this technology-oriented society, technology development itself is important, however it seems more important to utilize existing technology appropriately and deliver effectively to human life. As the computer became personalized after the appearance of PC, human-centered computing such as HCI and UCD had begun to appear. However, most of the researches focused on technology that made human being convenient to interact with computer such as computer systems design and UX development. In the technology-oriented society, it seems more urgent to apply existing technology to human life. In this paper, we propose a methodology, 'Digital Leveraging' which guides how to effectively apply technology to human life. Digital Leveraging is the way of convergence between technology and humanities.

Along with the development of Information Technology, online transactions through Internet have become more popular for the reasons of convenience and efficiency. In order to provide secure and reliable online transactions, an effective electronic payment protocol is crucial. In this paper, we propose a novel electronic payment protocol for digital product transactions with an offline arbiter to achieve fair exchange, automated dispute resolution, customer anonymity, and customer unlinkability. In our protocol a product token is adopted to eliminate the need of key management for digital product decryption in the offline arbiter. In addition, Elliptic Curve Cryptography (ECC)-based self-certified public key is utilized to further reduce computing overheads. According to our analysis, the efficiency of our protocol can be greatly increased in comparison with previous literatures.

The importance of Fundamental Geographical Information Framework for Digital City (FGFDC) is analysed, it provides all city agencies and units with uniform geographic references. Six kind of data are chosen as the core data sets of a FGDC, a web-based distributed mechanism is constructed to promote data sharing among different agencies. Elementary functional requirements of FGDC are analyzed, so that it can serve as a common distributed urban GIS. A practical FGFDC is developed for Yangzhou Development Administrative Region, and an 3D visualization system is developed within this framework.

본 연구는 빅데이터 산업과 디지털 광고 산업의 발전을 위한 비식별개인정보의 활용이라는 측면과 개인정보 보호 측면 사이의 갈등 관점에서 조망해보았다. 본 연구는 연구목적을 달성하기 위하여, 논문, 법조문, 행정 규정, 최근 언론 기사 등 문헌연구 중심으로 진행하였다. 특히 본 연구 주제 관련 국내외 현황과 제도 자료를 심층적으로 분석하였다. 본 연구 결과 디지털 맞춤형 광고에서의 비식별개인정보 보호 관련 주요 쟁점으로 '광고표현의 자유와 개인 인격권과의 상충', '식별 불가능한 정보의 개인정보화; '정보의 불균형'에 대해 분석하였으며, 이와 관련 디지털 맞춤형 광고에서의 비식별개인정보 보호 방안으로 '광고표현의 자유와 개인 인격권과의 조화' '고지와 동의 절차의 개선', '개인정보통제권의 강화'를 제안하였다. 본 연구는 현재 디지털 맞춤형 광고에서 비식별개인정보가 활발히 활용되고 있는 상황에서 비식별개인정보의 활용과 개인정보 보호에 대해 살펴보았다는 점에서 연구의 의의를 찾을 수 있다. 향후에는 본 연구 주제 관련 사례와 판례 중심으로 분석할 필요가 있다.

The digital image to be accepted as legal evidence, it is important to verify the authentication of the digital image. This study proposes a method of authenticating digital images through three steps of comparing the file structure of digital images taken with iPhone, analyzing the encoding information as well as media logs of the iPhone storing the digital images. For the experiment, digital image samples were acquired from nine iPhones through a camera application built into the iPhone. And the characteristics of file structure and media log were compared between digital images generated on the iPhone and digital images edited through a variety of image editing tools. As a result of examining those registered during the digital image creation process, it was confirmed that differences from the original characteristics occurred in file structure and media logs when manipulating digital images on the iPhone, and digital images take with the iPhone. In this way, it shows that it can prove its forensic authentication in iPhone.

The digital map version 2.0 is national base map which is used for frame work data, paper map making as well as geographic information system. National Geographic Institude has been research to make small scale digital map by using large scale digital map. NGI made from 25 1/5,000 digital maps to one 1/25,000 digital map ver 2.0 with map generalization system in 2003. However, they could not make 1/10,000 and l/50,000 digital map version 2.0 because of There is no portrayal on the scale 1/10,000 and 1/50,000 digital map in the existing regulations. therefore. We create the specification of the digital map on scale in order to make small scale digital map version 2.0 such as 1/10,000 and 1/50,000 scale.

Purpose This study aims to verify the mediating effect of the utilization performance of digital device on the relationship between user attitude and life satisfaction. Design/methodology/approach Using the data of 2018 Digital Divide Survey conducted by the National Information Society Agency(NIA), the mediating effect was verified by Baron & Kenny (1986)'s 3 step process, targeting 1,662 adults older than 55. Findings The result is as follows: first, the user attitude of middle and older aged people has a positive effect on their life satisfaction. Second, the effect of user Attitude towards Digital Device of middle and older citizens is partially mediated by the utilization performance of digital device. The results of this study indicate that when providing informatization education in the local community to promote the use of digital devices for the elderly, efforts should be made to grasp the level and inclination of informatization individually, and furthermore present improvements for wireless devices that the elderly can easily access in their daily lives. This study is expected to be a groundwork for a practical intervention to boost positive attitude towards using digital device to enhance the utilization performance of digital device and the life satisfaction of middle and older aged people.

South Korea is now recognized as a world leader in the field of digital government thanks to a president who had insight in the field of e-Government more than 20 years ago. Today, many countries around the world are establishing various strategies to cope with the great digital transformation beyond the industrial society and the information society. The Korean government is also establishing and promoting digital government policies to respond to such a global digital transformation. In South Korea, the digital platform government policy began in 2022. Therefore, it is an early stage of policy formation, and many details are not well known yet. Recently, the Korean government announced the vision, three goals, and five strategies for realizing a digital platform government. And specific digital platform government projects that can be implemented are selected. In order to successfully implement a digital platform government, the following three policies should be prioritized. First, the digital platform government should be approached from the perspective of total government innovation, not industry revival. Second, the political perspective should be excluded from ICT policy. Third, the vision and strategy of the digital platform government should be established and clearly presented to the public. And based on this, strong governance should be formed and strongly promoted centered on the leadership of the president.
