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.
