From time to time we will publish whitepapers here on issues relating to Web Filtering.
Web Filtering for Schools – The Requirement for Differentiated Filtering
This paper discusses some general requirements for a web-filtering system for academies and schools. It looks at, in particular, the need for differentiated filtering within the school environment because of the range of "audiences" to be effectively and appropriately filtered. This contrasts with a commercial environment where all the internet users are adults: this makes filtering much simpler as child safety and content "appropriateness" issues do not need to be addressed. The paper then goes on to discuss some of the architectural implications of this need for multi-level filtering. Download Whitepaper (pdf)
Google Images and Protex Filtering
This paper describes how Protex treats Google's image searches. Not only does it enforce the "safe-search" option that Google provides but also does additional filtering on the image thumbnails, content checks the results page and can block particular searches from taking place at all.
