Embodiment Construction

[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0024] The electronic document in the present invention refers to a disk file used to store any text information or binary information. It can be any editable document, such as a plain text file, a formatted character document, etc., and can also be a read-write document. Dynamically updated binary files, such as image files, executable program files, etc.

[0025] Different from the traditional way of manipulating electronic documents, when the content in the electronic document changes, we not only need to update the corresponding file of the electronic document itself, but also need to update the corresponding tracking file. Electronic documents record the content, and tracking file records is the process of cont...

Abstract

The invention relates to an electronic document dynamic protection technology based on unit tracking, which belongs to the technical field of data processing and protection in information technology.The technology comprises the following steps of decomposing the continuous change of the electronic document content into a series of independent update units, wherein the content evolution process information of the updating unit is continuously and completely stored in a tracking file which is composed of unit tracking corresponding to each updating unit. Using the information tracked by the unit to perform restore or replay operations on the update unit, and deducing the electronic document content forward or backward on the time axis. The invention has the beneficial effects that the existing problems can be solved from a dynamic process, the content protection of the traditional electronic document is upgraded from a static copy to a dynamic protection process, and a series of unit tracking information is continuously and completely recorded the content evolution process of the electronic document.

Description

technical field [0001] The invention relates to a dynamic protection technology for electronic documents based on unit tracking, which belongs to the technical field of data processing protection in information technology. Background technique [0002] Electronic documents are stored on disk when they are static or when they are closed, and they exist in the computer's memory when they are opened. Neither type of storage medium is absolutely secure. In practical applications, important electronic documents need to increase the level of content protection during the update and use process to prevent content loss caused by storage medium failure. [0003] Traditionally, the content protection of electronic documents is realized by copying, that is, in order to prevent accidental loss, the electronic documents to be protected are copied to different storage media, including storage on a remote network (cloud storage). However, the copy of the electronic document is a static co...
