Embodiment Construction

[0041] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, wherein the schematic embodiments and descriptions are only used to explain the present invention, but not as improper limitations to the present invention.

[0042] File trace: It is an attribute value of a document, which can be used to add additional information to mark the original document.

[0043] The anti-leakage processing method of mail data with traces proposed by the present invention is aimed at various requirements such as multiple forwarding, copying and replacement, illegal dissemination, etc. after the mail is sent, and has a certain tracking and positioning function for the mail content after the mail is sent out. This method deals with the identification of email attachments and the addition of traces at two technical levels, and solves the problem that data leakage in email transmission is difficult to trace.

Abstract

The invention discloses a file information leakage prevention and tracing method and system. The method comprises the following steps: receiving and parsing an email to be sent, and extracting email information; judging whether tracing information needs to be added to the email according to an email analysis result and an email leakage prevention policy; and determining to add the tracing information to the email according to the above judgment result, and then forwarding the email, or directly forwarding the email. By adoption of the scheme of the invention, the problems of information leakage, multiple times of forwarding, incapability of tracing caused by in an email transmission process can be effectively solved, the multiple times of transmission and illegal use of the email can be effectively avoided, and the loss of enterprises caused by information leakage is avoided; and the safe delivery and legitimate use of email contents are improved.

Description

technical field [0001] The present invention relates to the field of data security, in particular to a method and system for preventing leakage and source tracing of file information. Background technique [0002] Trace is a technology of adding attribute values ​​to documents, which is used to add some additional information to documents, pictures, multimedia and other content, and to mark the content of the email attachment. As an important tool for information transmission, emails carry a large amount of sensitive information during the transmission process. In order to prevent information leakage and trace the source of information, specific traces are added to the email attachments when the email is sent, so that the email is easily transmitted during the transmission process. It is easy to know which company and department the email belongs to, the subject and event of the email, and whether to allow external transmission and other alarm information, which can effectiv...
