URI Immunization: Eluding Spams in Participatory Systems

This paper proposes “URI Immunization” for eluding Web spams like Trackback spams in participatory systems open to the general public. The proposed method is inspired from the immune system of organisms, and by applying the basic strategy of organisms, “change,” on the construction of changing URIs, the author established an effective method for eluding spams. The effectiveness of the method is validated by the analysis of real accesses collected at our participatory Website, “Eyes on the Typhoon.”
