Method and program for generating odf document by using CA signature for data integration

Abstract

The invention discloses a method for generating a document through dynamic synthesis of a CA digital signature and data and structured integration of data and an implementation program of the method, and belongs to the field of class document security processing through a computer technology. The method takes the CA technology as a core, and the document is generated through computer programs, an ODF standard protocol, ods and odt document templates and related parameter configuration; the method comprises the following steps: dynamically synthesizing related elements such as characters, two-dimensional tables, mathematical formulas, static pictures, vector pictures and statistical charts, structuring corresponding metadata information, combining with CA electronic signature information, generating a document after security authentication of a CA digital authentication platform, storing structured data in a database, and storing the structured data in the database. And synchronously storing the unstructured form and the related configuration as unstructured data. The technology can meet the safety requirement of highway construction project quality inspection data filling and reporting and does not depend on tools such as Excel or Word, and the generated document has the advantages of being friendly in user interface, good in typesetting effect, good in platform compatibility and high in safety.

Description

technical field [0001] The invention relates to a method and a program for integrating data from different sources according to certain rules, performing digital authentication through CA technology, and automatically generating documents embedded with digital signatures, belonging to the field of document processing using computer technology. Background technique [0002] At present, data electronization has penetrated into various industries, and one of the subsequent application directions is the visualization and security of electronic data. The common ones are online visualization WEB form and offline visualization (excel without signature method), etc., such as In the field of industry forms, it is necessary to generate some text input boxes on the WEB page. When there is a lot of data, the form will be stretched for a long time. It is not intuitive to fill in the form manually, and the operation is cumbersome. It cannot be copied and pasted as a whole, and there is no ...

[0002] At present, data electronization has penetrated into various industries, and one of the subsequent application directions is the visualization and security of electronic data. The common ones are online visualization WEB form and offline visualization (excel without signature method), etc., such as In the field of industry forms, it is necessary to generate some text input boxes on the WEB page. When there is a lot of data, the form will be stretched for a long time. It is not intuitive to fill in the form manually, and the operation is cumbersome. It cannot be copied and pasted as a whole, and there is no safe digital verification; the second method is First customize the static excel template (when the document contains statistical charts, it needs to be combined with Office components such as Excel), and copy and paste manually to generate the final document. The main problems are low work efficiency, high error rate, and cumbersome calculations in EXCE. It cannot be stored in a structured way; the third method is to use the programming interface to manipulate the office (including word / excel) templates. Since Microsoft only opened up part of the interfaces of office documents, this kind of solution is highly complex, the generated documents are not compatible, and the typesetting effect is also poor. No, once the document format is fixed, it will be very difficult to make secondary adjustments; the fourth method is to use the development interface of excel to generate documents. Although pdf is a completely open standard, it is still very difficult to develop through API. The shortcomings of the method are consistent with the method three
