Open Source Content Filtering

Censoring The Open Nature Of The Internet

Open source content filtering is a method to restrict what sites a user can visit on his or her computer. Open source content filtering looks at the URL of the desired site and scan through the site's content for restricted keywords and choose whether to block or permit the connection. Open source content filtering works by using either a whitelist or a blacklist: The previous allows access only to sites, particularly chosen by whoever set up the filter, and the latter limits access to undesirable sites as determined by the standards installed in the filter.

Open source refers to any program whose source code is made accessible for use or modification as users or other developers see fit. Open source software is normally created as an open, coordinated effort by developers and made freely available.

Filters are often installed either as a browser extension, as an independent program on the PC, or as a major aspect of a general security solution. Some search engines also highlight filters to remove undesirable pages from search items. Open source content filtering can be done on the network side, either by an ISP or on the business side, to restrict the Internet access of numerous users at once. Open source content filtering has a primary customer base in businesses that need to keep employees from getting to sites that don't relate to their jobs.

Open source content filtering is commonly used to block access to sites that ordinarily host malware, such as those identified with pornography or gambling. The most advanced open source content filtering can even shut data that is conveyed over the Web, to guarantee that delicate information isn't released.

Companies that use open source content filtering software keep up staffs of reviewers who examine the Web for objectionable sites. However, given that the Internet is developing much faster than the software companies can review it, it is only logical that the review process depends on automation. Even if there were enough reviewers to index the whole Web, the blocked list would be outdated by the time they finished.

Once a user sets up an open source content filtering program to limit access to prohibited materials, the program works in two distinct ways when a Web connection is made. First, it checks to ensure the web page is not on the software’s “blocked” web page list. Second, it previews requested web pages and incoming e-mails by checking them against a blacklist. If the webpage or e-mail account is recorded in both databases, the page or message won't be shown on the screen, and rather a page will show up advising the client that the page or message is blocked. Most open source content filtering programs allow the primary user to add Web sites to an “always allow” list that supersedes the filter’s databases.
