1. Background
The informatization construction of Wuhan Qiaokou District Government (abbreviated as Qiaokou District) has always been in a leading position in the entire Wuhan city-level units, and the application of informatization is early and wide-ranging. Qiaokou District successfully applied the Ginger electronic signature system in early 2004, which is mainly used in the official document transmission system. The electronic signature system protects the secure exchange of electronic official document content of various units and also solves the problem of traditional signatures. After three years of successful application of the electronic signature system in Qiaokou District, due to the rapid development of information technology, various external environments (hardware and software) have been continuously upgraded, such as electronic official document exchange system, WINDOWS operating system, OFFICE office system, and third-party The application system is upgraded. At present, the official document format of Qiaokou District has changed from the original Office 2003 to Office 2007, and the operating system has also changed from Windows XP to Windows Vista. While upgrading the external system, it is necessary to solve the security, applicability, interoperability and other issues of official documents, and to be in line with the current national official document standards, and to solve the problem of difficult identification and interaction of paper documents. Therefore, the government of Qiaokou District, Wuhan City It was decided to upgrade the system comprehensively and adopt a comprehensive solution of two-dimensional bar code and electronic signature of Jinge official documents.
Official document two-dimensional barcode technology is currently the main application technology of paper-based official document information recognition after printing official documents in my country. Its advantages include large amount of stored information, high information security, and ease of use. In order to solve the actual two-dimensional barcode application of official documents by the Qiaokou District Government of Wuhan City, Ginger Technology pioneered the application of electronic signature and two-dimensional barcode in response to the actual process application of customers. It is as natural and convenient as the existing signature operation, and the application is intuitive. At the same time, it is based on the national “GB0626-2005 (Regulations for the use of two-dimensional barcodes in official documents of the government)” as the standard.
Two, program analysis
The government informatization process of Qiaokou District, Wuhan City is mainly for collaborative office applications, and there are a large number of document manipulation applications. The solution first solves the online editing application of the document, and the interactive application of the document on the server and the client. At the same time, in some key approval processes, the plan also needs to address the signing, protection, locking, verification, and printing of documents. Therefore, a complete, independent electronic signature application that can be embedded in the system is required in the document setting. The solution also needs to control the printing of the document, and when printing the document, it needs to output a two-dimensional bar code covering the official document information.
In addition to solving the application of internal documents, the informatization process of the Qiaokou District Government of Wuhan City also accepts and archives documents from other superior authorities. For documents with two-dimensional barcode information, scanning and identification are also required.
Based on the basic customer demand analysis, the solution proposed by Jinge Technology is to increase the online version of the Jinge electronic signature system based on the use of Jinge document editing middleware; to solve the problem of barcode generation and reading, develop The bar code technology is added to the electronic signature function to realize the automatic generation of bar codes, and its bar code recognition is also a function embedded in the client standard.
