Design of Document-HTML Generation Technique for Authorized Electronic Document Communication
황현천(Hyun-Cheon Hwang),김우제(Woo-Je Kim) 한국산업경영시스템학회 2021 한국산업경영시스템학회지 Vol.44 No.1
Electronic document communication based on a digital channel is becoming increasingly important with the advent of the paperless age. The electronic document based on PDF format does not provide a powerful customer experience for a mobile device user despite replacing a paper document by providing the content integrity and the independence of various devices and software. On the other hand, the electronic document based on HTML5 format has weakness in the content integrity as there is no HTML5 specification for the content integrity despite its enhanced customer experience such as a responsive web technology for a mobile device user. In this paper, we design the Document-HTML, which provides the content integrity and the powerful customer experience by declaring the HTML5 constraint rules and the extended tags to contain the digital signature based on PKI. We analyze the existing electronic document that has been used in the major financial enterprise to develop a sample. We also verify the Document-HTML by experimenting with the sample of HTML electronic communication documents and analyze the PKI equation. The Document-HTML document can be used as an authorized electronic document communication and provide a powerful customer experience in the mobile environment between an enterprise and a user in the future.

신뢰적 공인전자문서 소통을 위한 Document-HTML 시스템의 설계 및 구현
황현천 ( Hyun-Cheon Hwang ),김우제 ( Woo-Je Kim ) 조선대학교 공학기술연구원 2021 공학기술논문지 Vol.14 No.2
Electronic documents have become essential for communication in the digital era rather than paper documents. An electronic document, such as a PDF document that has the same layout as a paper document, is delivered through a delivery channel such as e-mail. Moreover, in the mobile era, delivering an HTML document to a mobile application has become a means of communication. However, unlike a PDF document, an HTML document is composed of related external resource files such as an image. There is no explicit specification to guarantee the content integrity against unauthorized content modification. In this study research was conducted into Document-HTML specifications that guarantee document integrity like a PDF document and provide a better customer experience in the mobile environment based on HTML5. Furthermore, we designed and implemented a Document-HTML system in a cloud computing environment. The Document-HTML system provides stateless REST API for Document-HTML document creation and validation, and the Document-HTML document provides RSA cryptography level content integrity by using a digital signature based on PKI. The Document-HTML system can be used as a secure customer communication platform in enterprises to provide content integrity and a better user experience in the mobile environment.

MQTT 프로토콜 기반 협업 메신저 시스템 설계 및 구현
황현천 ( Hyun Cheon Hwang ),박지수 ( Ji Su Park ),손진곤 ( Jin Gon Son ) 한국정보처리학회 2014 한국정보처리학회 학술대회논문집 Vol.21 No.2
현재 네트워크 시스템은 유선에서 무선으로 발전하면서 많은 업무가 모바일 기반의 업무로 변화되 고 있다. 그 중 대표적인 것이 모바일 오피스 시스템으로 중요 구성요소 중 하나인 커뮤니케이션은 구 성원간의 단문 메시지 서비스(SMS)이다. 그러나 최근 무선 환경의 발전으로 단문 메시지 전송 방식 이 SMS에서 모바일 메신저로 변화하고 있으나 그에 대처하지 못한 시스템들이 있다. 이에 본 논문에 서는 모바일 오피스 시스템에서 사용되고 있는 SMS를 대체하여 MQTT(Message Queuing Telemetry Transport) 프로토콜을 이용한 협업 메신저 시스템을 설계 및 구현한다.

ANP 모형을 이용한 금융기업의 옴니채널 고객 시스템의 중요 구축 요소 분석
황현천(Hyun-Cheon Hwang),김우제(Woo-Je Kim) 한국산업경영시스템학회 2020 한국산업경영시스템학회지 Vol.43 No.1
The omni-channel customer system is the communication system between enterprise and customer via multiple channels such as mail, email, SMS, and mobile. The omni-channel customer system complements each other channel through the integration of each channel. The purpose of this research is to derive key factors and calculate the weights that a financial enterprise considers when adopting the omni-channel customer system. For this research, we analyzed the request for proposal documents used for the omni-channel customer system implementation projects in the financial enterprise. Also, we derived, classified, and stratified the key factors to be considered for the introduction of the omni-channel customer system in the financial enterprise. As a result of analyzing the key factors, customer experience, operations, and security were identified as the components of the top category in introducing the omni-channel customer system in the financial sector. Furthermore, the weight for each key factor was calculated by using ANP. As a result of ANP, operations, customer experience, and security were important in order. Also, the degree of easiness for connecting with other systems and the various abilities for representing the contents of the omni-channels were derived as the important key factors.
