E-government affair management service system and method

The invention provides an e-government affair management service system and method, and the system comprises a time module, a position module, an encryption module, a seal generation module, and a seal terminal. The time module obtains local time based on UTC (Coordinated Universal Time); the position module obtains a precise IP address of the computer and converts the precise IP address into latitude and longitude coordinates; the encryption module converts time information and position information into a decimal short numeric string, and the seal generation module combines the numeric string generated by the encryption module with a seal pattern into a whole and affixes the whole on an electronic file; and the seal terminal automatically adjusts the number on the seal surface to be consistent with the numeric string according to the numeric string generated by the encryption module, and is used for stamping on a paper file. 本发明提供一种电子政务管理服务系统及方法，包括时间模块、位置模块、加密模块、印章生成模块、印章终端，时间模块获取基于UTC（协调世界时）的本地时间；位置模块获取电脑精准
