Method and device for displaying document in browser

Abstract

The invention provides a method and a device for displaying a document in a browser. The method comprises the following steps that: a browser host process establishes a plug-in separate process of a corresponding document processing procedure according to a request for accessing the document of a user, wherein the plug-in separate process is a subprocess of the browser host process; the plug-in separate process initiates a browser page; and the browser page calls a plug-in of the document processing procedure to analyze the document and display the page. By the method and the device, the influence of the vulnerability of the document processing procedure on the application of the browser can be avoided, and a user computer is further prevented from being attacked by virus.

Description

technical field [0001] The present application relates to the field of data processing, in particular to a method for displaying documents in a browser, and a device for displaying documents in a browser. Background technique [0002] The PDF format is an electronic document format. When a user clicks on a PDF file link on the Internet, the system does not directly open the file, but displays a file download window to ask the user whether to download the file. Download the designated PDF file to the hard disk, and then use the Acrobat Reader software, which is a special browser for PDF files, to browse. The operation is cumbersome and time-consuming. [0003] In order to help users better browse PDF files on the Internet, Acrobat Reader has provided IE plug-in function since 4.0, which can use itself as a plug-in of IE browser to add PDF file browsing function to IE. After activating this function, if the user encounters a PDF file when browsing the web, the system will aut...

AI Technical Summary

Problems solved by technology

[0004] The problem existing in the above prior art is that the current PDF program loopholes occur frequently. If the PDF file accessed by the browser is a Trojan horse virus that can trigger the PDF loophole maliciously constructed by an attacker, it will not only cause the browser process to crash and become unusable, but also cause the browser process to crash and become unusable. Download and execute a malicious Trojan horse without knowing it, poisoning the user's computer and possibly causing economic losses to the user

[0005] Similar to PDF programs, document processing programs such as Word, Excel, and PowerPoint also have multiple vulnerabilities. When the plug-in of the document processing program is called in the browser to open the corresponding document, there will also be problems similar to PDF programs.
