Document information embedding and tracking methods and systems and proxy service equipment

Abstract

The invention provides document information embedding and tracking methods and systems and proxy service equipment. The document information embedding method comprises the following steps: receiving a first office document uploaded from a source terminal node in a local area network to an extranet; generating a trace file in an xml (extensive markup language) format from forward behavior information according to a configuration strategy, wherein the forward behavior information comprises at least source terminal node login information, an IP (Internet Protocol) address of the source terminal node and office document upload time; embedding the tracking file in the xml format into the first office document to obtain a second office document for uploading. After information leakage, related information generated by a secret leakage behavior can be acquired by examining or decoding operator information in the leaked Office document.

Description

technical field [0001] The invention relates to the technical field of computer network security, in particular to a document information embedding and tracking method and system of an office document and a proxy service device. Background technique [0002] With the development of Internet technology, the business of traditional enterprises has begun to migrate to the Internet. While enterprises feel the huge development opportunities brought by the Internet, they are also facing new challenges. Among them, information leakage is one of the challenges. At present, the commonly used methods for document security management include embedding watermark encryption in documents, setting up gateway audit devices on the switch side, and classifying and supervising documents that need to be kept secret. But these are limited to the document monitoring and supervision in the early stage, and the tracking of Office documents in the later stage is usually realized through the gateway...

Problems solved by technology

The most direct defect of audit equipment is that it is not conducive to long-term storage of audit information due to limitations such as storage capacity.

In addition, when internal documents are leaked and reposted on multiple websites, it is very difficult to trace the source of the leak from multiple websites

So is there still a more effective way to track the source of Office documents?
