Method and device for recording trace information of electronic file

Abstract

The invention provides a method for recording trace information of an electronic file, which comprises the following steps of: creating an XML (Extensible Markup Language) file for recording modification historical information and the trace information of a text of the electronic file, wherein the modification historical information comprises a version identifier and a modifier information of each modification version and the trace information comprises one or a plurality of modified modification types and modification character contents of each modification version associated with each version identifier; and each when modifying the electronic file, recording the modified modification historical information and trace information into the XML file. Correspondingly, the invention provides a device for recording the trace information of the electronic file. The trace information recorded according to the invention has strong independence and compatibility and high understandability and is easy to integrate with other information systems and store for a long time. Moreover, the authenticity o the trace information can be identified.

Description

technical field [0001] The invention relates to the technical field of electronic file processing, in particular to a method and device for recording electronic file trace information. Background technique [0002] With the popularization of computer technology, many enterprises and individuals generally use electronic files to process data and save information. Usually, electronic documents often need to go through multiple revisions from the first draft to the final draft. The trace information refers to the previous modification process, modification content and modification traces of each processing step in the process of finalizing the electronic document. Retaining trace information can ensure the traceability and non-repudiation of file modification information. For example, with the popularization and development of office automation, many institutions and institutions use the office automation system to draw up official documents. In the process of drafting offic...

Problems solved by technology

From this article, we can see that there are currently several ways to deal with file traces: one is to realize the trace processing by designing a multi-value calculation field in the form. The disadvantage of this method is that it can only issue comments and leave It is not possible to leave traces on the modification of the text of the file; the second is to realize the processing of leaving traces by programming the word file object. Although this method can control the modification and deletion permissions of the text file through programming, in the actual file editing, the user can completely bypass it. The modification and deletion permission restrictions set by this method modify the file, so there are loopholes in this method itself; the third is to use the word template to realize the processing of leaving traces. Although this method uses macros to restrict some functions of word, However, macros can be prohibited and re-enabled, and users can completely bypass some of these links to modify files. Therefore, there are loopholes in this method itself; the fourth is to realize the trace processing by using integrated development environments such as VB or delphi to develop controls , the disadvantage of this method is that it adopts self-developed controls, it is difficult to integrate into other information systems, and the independence and compatibility are low

[0004] In addition to the above shortcomings, these methods are basically based on the modification traces and annotation information of word. From the perspective of the development history of the word file format itself: the existing format is not open, and the old version of word cannot be opened with the newer version of word software. Version incompatibility issues such as file and content format changes, so the word file format is not suitable for long-term storage

Moreover, these methods all lack the authentication mechanism for leaving trace information, and cannot maintain the authenticity of the text modification (that is, the authenticity of the modified content cannot be verified), and non-repudiation
