目的是为了打击假学历，本系统能够有效地规范电子学历的操作流程，降低黑客和内部非法人员对资料的篡改的可能性，提高电子学历的安全性和权威性。

整个系统主要分为两个部分：第一部分是专门对电子学历进行保全管理，可对每份电子学历生成一个唯一的电子戳，即.edu文件（里面包含时间戳、hash值等数据），然后把电子戳上传服务器，从而实现对电子学历的保全。

第二部分是认证，首先在客户端本地对原电子学历文件进行重新计算电子戳，并与保全时生成的电子戳对比是否一致，来判定电子学历是否被篡改，如果一致，再把重新计算的电子戳上传服务器，与保全时上传服务器的电子戳进行比较，从而实现对电子学历的认证。

-The purpose is to combat fake degree, the system can effectively regulate electronic education operational processes, reduce the possibility of hackers and internal data tampering illegal personnel, improve security and electronic education authority. The whole system is divided into two parts: The first part is dedicated to the preservation of electronic education were managed for each electronic education can generate a unique electronic stamp that .edu file (which contains a timestamp, hash value and other data), and then The electronic stamp upload server, enabling the preservation of electronic education. The second part is certified, the first locally on the client to the original electronic document to recalculate education electronic stamp, an electronic time stamp comparison with the preservation generated are the same, to determine whether the electronic education has been tampered with, if the same, then recalculated electronic stamp upload server, the server upload and pres
