基于邮件解析的区块链电子票夹系统

电子发票和财政电子票据（电子票）在人们日常生活中无处不在，然而当前电子票对用户而言仍然存在着管理困难、归集过程复杂、易重复查验、难以控制等问题。提出基于邮件解析的区块链电子票夹系统，主要服务于报销者与财务人员。目前电子票普遍支持邮箱接收，而一般邮箱不具备电子票信息解析功能，难以进行查阅管理。因此，自主研发一套邮箱服务系统，专门接收含电子票文件或链接的邮件，并能将电子票关键信息准确解析出来，发送至电子票夹应用平台。电子票夹应用平台支持Web网页与小程序的可视化显示，方便用户查看与管理电子票，同时支持一站式报销和入账。电子票每一次状态变更都会同步记录到区块链上，以保证电子票信息的完整性、唯一性与可追溯性。

E-Bill Blockchain System Based on Mailbox Service

Invoices and financial bills （e-bills） are ubiquitous in our daily life. However， for users， e-bills still have problems such as management difficulties， collection difficulties and repeated inspection. This paper proposes an e-bill blockchain system based on mailbox service， which is mainly used for reimbursement staff and financial officers. At present， e-bills are received by email， while general mailbox service does not have the function of e-ticket information extraction， so it is difficult to consult and manage. Therefore， we developed a mailbox service system， which specially receives emails containing e-bills， accurately analyzes the information of e-bill and sends it to the e-bill application platform. The e-bill application platform is convenient for users to view and manage e-bills. Users can reimburse and post e-bills easily. Every state change of e-bill will be recorded on the blockchain synchronously to ensure the integrity， uniqueness and traceability of e-bill.
