چکیده

Undesired mail, such as commercials, is called spam in mail services. Spit is what spam is for mail services, unsolicited communications. The difference in spit and spam is that spam can be checked before the delivery to the recipient and spit can be reliably detected only after the call is made. Voice over IP (VoIP) community has adopted a more peer-to-peer approach, in which the registrars and proxies are located on the participating nodes, rather than on separate servers. Industry has also been quite keen in the development of such approach, especially ones that use identifier-locator split protocols. The lack of centralized authorities and the usage of long trust paths make detecting spit even harder a task. In this paper we describe a system to disseminate information of friendships that are based on an end-host based identifier-locator split protocol. In our solution the existing buddy lists are used to introduce one-hop connections in the system. In our system we rather detect friends than spit or spitters. Moreover, our solution can be generalized for situations where the before-hand inspection of the content is impossible or otherwise hard to implement.

VoIP/SIP is taking place of conventional telephony because of very low call charge but it is also attractive for SPITters who advertise or spread phishing calls toward many callees. Although there exist many feature-based SPIT detection methods, none of them provides the flexibility against multiple features and thus complex threshold settings and training phases cannot be avoided. In this pape...

Sifting through Nutritional Science: Separating Hype From Scientific Research

Information is often piecemeal, taken out of context, or not based in sound science—and often contradicts other “authorities.” People are increasingly making decisions based on anecdotes and testimonials rather than credible sci...

Constructive algebraic integration theory

For a long time people have been trying to develop probability theory starting from ‘finite’ events rather than collections of infinite events. In this way one can find natural replacements for measurable sets and integrable functions, but measurable functions seemed to be more difficult. We present a solution. Moreover, our results are constructive (in the sense of Bishop).
