Embodiment Construction

[0041] The invention provides a method for collecting, analyzing, counting and feeding back file circulation information at a terminal by using a data leakage prevention system of a host computer. This method is optimized based on the existing data leakage prevention terminal function. According to the file version information, the file tracking function is established, and the circulation chain is constructed for the internal circulation of the files in the enterprise, and the circulation analysis and statistical results of the documents are generated in a timely and effective manner, so as to improve the circulation efficiency and security. .

[0042] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

Abstract

The invention discloses a data leakage early-warning method and system based on document circulation. The method comprises the steps of: binding terminal feature information, user information and timestamp information to a document, so that document version information is formed, and recording the document version information in a document digital signature; after the document is operated, recording updated document version information, and furthermore, updating the document digital signature by utilizing the updated document version information; taking the document version information beforeoperation and the updated document version information together as a piece of document version change record information, and uploading the document version change record information to a server; obtaining an document circulation abnormity index of the document by calculation by the server according to the document version change record information; and, according to the document circulation abnormity index, in combination with an early-warning strategy, determining whether data leakage early-warning on the document is carried out or not. By means of the technical scheme in the invention, a circulation chain can be constructed for a circulation document; a circulation analysis and statistical result of the document can be effectively generated in time; and the circulation efficiency and security are improved.

Description

technical field [0001] The invention relates to the field of data security, in particular to a data leakage early warning system method and system based on file circulation. Background technique [0002] With the rapid development of information science and Internet technology, security issues have intensified, and information security has received unprecedented attention. Many enterprises and institutions have used the OA system for electronic flow management internally, but the OA system cannot provide strong support for the internal circulation of ordinary documents. Due to the variety of transmission tools used, considering factors such as convenience, they cannot be effectively unified, which may cause accidental leakage of key data or files. In this regard, Beijing Mingchao Wanda Technology Co., Ltd. proposes a method for analyzing and counting file transfer patterns aimed at end users of the data leakage prevention system. It analyzes file version information logs an...
