Abstract(in English) Telephony systems are changing over from traditional PSTN to Voice over IP. In the VoIP environment, nuisance calls may increase due to the lower cost of VoIP and the ease of automatic calling system using computer. To block these nuisance call, we can make use of white list access control list. But this method blocks not only nuisance calls, but also necessary calls. To solve this problem, we introduced call blocking mechanism using notion of web of trust. In this mechanism, the longer the telephone number propagates, the less the familiarity between caller and callee becomes. In this paper, we explain the model of our call blocking mechanism for VoIP, and discuss the effectiveness of our method using prototype system.
