Problems solved by technology

Traditional database query and audit methods can solve the retrieval and analysis of a large amount of "static" data, but under the application mode of this system, such frequently updated "dynamic" label information will become a major challenge for accurate tracking and comprehensive auditing

Embodiment Construction

[0018] step one

[0019] First of all, the file track tracking tree generation tool builds a table based on the collected information about the spread of files in the network and the operation information on files. The specific operation steps are as follows:

[0020] When the computer installed with the electronic file system generates new files or performs operations on files, file information and operation information will be uploaded in real time. When the administrator performs query track operations on a file (other operations are also possible), input the name of the file to be queried, and the system will prompt the original version and other copies of the file (the prompt information includes the name of the file copy, operations on the file, operator information, operating time, etc.), the administrator determines to use the file or a copy of the file as the root node of the tree according to his own needs, and then determines to generate a file track tracking tree...

Abstract

The invention belongs to the field of electronic file security control, and provides an audit and analysis method based on file trajectory tracking trees. Millions of pieces of file tag information are dynamically stored in a database of an electronic file security control system, and an efficient and reliable tag information audit and analysis technique needs to be developed to meet the requirement for audit and analysis of electronic files under the circumstances of large data volume, dynamic updating and multi-dimensional circulation. The file trajectory tracking trees are located between a database layer and an audit and analysis layer, a data storage structure body in the form of a file trajectory spreading tree graph is formed through certain association, partition and recombination of data after the tag information is extracted from an updating database table, the peak of each tree represents a file builder, child nodes of each tree represent the spreading range of the corresponding file, and branches of each tree represent the spreading trajectory of the corresponding file. Next, the audit and analysis layer directly operates the file trajectory tracking trees, so that the calculated quantity is reduced.

Description

technical field [0001] The audit analysis method based on file track tracking tree belongs to the field of electronic file security control. Background technique [0002] In order to easily observe and audit the circulation process of a file and its copies, a data structure representation method called "file track tracking tree" is proposed to simplify the workload of audit analysis. After the file track tracking tree extracts the required information from the updated database table, after certain data association, division and reorganization, a data storage structure with a file track propagation tree diagram style is formed. The vertex of each "tree" Represents the creator of the file, its child nodes represent the spread range of the file, and the "twig" represents the spread track. [0003] One of the core functions of the electronic document security management and control system is to track the circulation track of the document by adding label information to the docum...
