Hello, I mean by content pollution the action of publishing files with fake metadata. This could be done to disseminate spam, virus or other malwares. Multiple decoy insertions could affect the Freenet network utility.
I have a short paper (2 pages) describing my current work, including a description of my strategy to mitigate content pollution: http://inf.ufrgs.br/~frsantos/files/funnel_infocom2009-sw.pdf<http://inf.ufrgs.br/%7Efrsantos/files/funnel_infocom2009-sw.pdf> In a previous work, I implemented the strategy in a BitTorrent community and the results were satisfactory. If it does not fit a relevant project, which one from your list is related to "user generated content" and "security" topics? Suggestions? Thank you! Regards.
