| Research Abstract |
As an anti-spam method, a filtering technology based on URLs for advertisement, phishing, and so on (target URLs) is frequently used. Recently, however, to avoid this technology, spammers use a sophisticated countermeasure such as frequent change of target URLs. Therefore, a new method against this countermeasure is required. In this research, we established an anti-spam method based on basically unforgeable characteristics such as the registration date of the domain in a target URL, the behavior of the DNS (Domain Name System) server of the domain related to the target URL, and so on.
