Embodiment Construction

[0034] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] refer to figure 2 , showing a flow chart of steps of an embodiment of a document printing method of the present invention; image 3 A flow chart of steps of another embodiment of the document printing method of the present invention is shown.

[0036] Combine below figure 2 and image 3 The document printing method of the present invention will be described in detail.

[0037] Windows provides several printer-only functions. These printer-specific functions (including StartDoc, EndDoc, StartPage, and EndPage) are responsible for organizing the printer's output onto paper. The document printing method of the embodiment of the present invention needs to intercept the above-mentioned StartDoc and EndPage functions.

Abstract

The embodiment of the present invention provides a document printing method and system, the method comprising: intercepting the StartDoc function; acquiring the first HDC parameter value of the StartDoc function; intercepting the ExtTextOut function; acquiring the second HDC parameter value of the ExtTextOut function; If the first HDC parameter value is identical to the second HDC parameter value, then obtain the text page content to be printed in the ExtTextOut function; judge whether the text page content includes a preset keyword; if so, when intercepting When the EndPage function is reached, add a preset watermark to the content of the text page; print the content of the text page added with the preset watermark; if not, when the EndPage function is intercepted, print the content of the text page. The invention can only print watermarks on text pages with sensitive data, greatly reducing the burden of business processing, while ensuring the safety of printed sensitive data and avoiding the risk of embezzlement of sensitive data printed without watermarks.

Description

technical field [0001] The invention relates to the technical field of computer security, in particular to a document printing method and system. Background technique [0002] As more and more office systems turn to B / S (browser / server) structure, users can use browsers to conveniently complete functional operations without installing additional terminal software. However, when a browser accesses a business system and requests to print a document (such as a financial form or a business statement), the watermark control methods for the document in the prior art mainly include prohibiting printing, or adding watermarks indiscriminately, or allowing printing, but the printing Documents are not watermarked. [0003] Such as figure 1 As shown, in the scheme of the prior art, after the print operation is intercepted, if the data source of the document to be printed is found to be a sensitive business system, a watermark will be inserted into all documents to be printed from the ...
