신뢰적 공인전자문서 소통을 위한 Document-HTML 시스템의 설계 및 구현

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.
