OntoSPIT: SPIT management through ontologies

VoIP enables new ways for communication. At the same time, it provides new means, in terms of transmitting bulk unsolicited messages and calls, namely SPam over Internet telephony (SPIT). In this paper, we propose a conceptual model, based on an underlying ontology, which describes the SPIT domain. The ontology provides capabilities, such as modeling the SPIT phenomenon in a SIP-based VoIP environment, a common understanding of SPIT domain, as well as reusable SPIT-related knowledge interoperability, aggregation and reasoning. We demonstrate that the proposed ontology, combined with a set of SPIT identification criteria, as its underlying axioms and rules, could enhance the correlation and management of SPIT incidents. It could also support SPIT detection, thus facilitating the better protection of VoIP environments in a holistic, cooperative, and effective way.
