System and method for tracing alteration of graphics file

Abstract

A drawing change tracking method comprises: whether the property of a drawing after change is the same as the property of an original drawing is judged; if the property after change is not the same as the original property, the drawing is judged to be modified, and the modified content is saved to a change log; if the property after change is the same as the original property, whether the drawingis downloaded is judged; when the drawing is downloaded, a sequence number is allocated to the drawing, and the drawing and the sequence number are bound; whether the drawing is sent by an e-mail after being downloaded according to the mail parameters sent by a WEB server is judged; when the drawing is sent by the e-mail after being downloaded, the drawing which is bound with the sequence number is searched by the sequence number; the mails on the WEB server are accessed and the drawing in the mail is deleted. In addition, the invention also provides a drawing change tracking system. By usingthe invention, the security management of the drawing is enhanced.

Description

technical field [0001] The invention relates to a system and method for tracking change of graphic files. Background technique [0002] At present, information security has generally become the focus of various enterprises and companies. As a manufacturing enterprise with mold design as its core competitiveness, the security of mold design drawings is the focus of the information security departments of these enterprises. [0003] At present, many enterprises have their own drawing management system to centrally manage the mold drawing files within the enterprise. The centralized management of mold drawing files brings mold designers no longer to worry about the loss of their own design drawing files and version control issues, and at the same time As a centralized management of mold drawing files, it can also share mold design experience. [0004] However, the centralized management of mold drawings and files has brought a very big security risk: leakage of mold drawings a...

[0004] However, the centralized management of mold drawings and files has brought a very large security risk: leakage of mold drawings and files

In order to prevent image files from being leaked in the image file management system, the administrator of the image file management system usually encrypts the image files after they enter the management system. Can be opened by some graphics drawing software

Moreover, the administrator of the image file management system cannot obtain the information of the image file change and the root cause of the image file leakage
