The Information Backups Based on the Chrome Extension and Native Program Communication Mechanism

Abstract

The browser is an important gateway to the Internet. It needs to use the browser extension to improve the browser's functionality in order to more easily complete a specific task. Browser-based applications can use the browser extension to complete the access to local features. The browser does not have direct access to local features because of the security, but the chrome extension provides a mechanism for exchanging information with local programs. Using the local messaging mechanism and JSON format of the message, follow a certain protocol specification, it can flexibly achieve the interaction between the chrome extension and the local program. This mechanism can improve the function of the browser and complete the task that browser cannot complete. This paper implements a framework through this mechanism and this framework is designed to capture web-specific content that makes it very flexible to get a variety of web content and it is very helpful for developing various browser-based applications.
