As the internet and I-commerce have been developing. a novel method for marketing is needed. A new advertisement using E-mail is becoming popular, because it has characteristics with low costs and relative efficiency. However. as the spam mails are increasing rapidly, mail service companies and users are deeply damaged in their mind and economically. In this paper, we design a hierarchical spam mail blocking policy through cooperation of all the participants-user, administrator, ISP to cut off the spam mail efficiently and Propose an efficient model to block and manage the spam mails based on the Policy. Also we prove the efficiencies and effectiveness of the proposed model through evaluation process .

요즘 전자우편(E-mail) 서비스를 사용하게 되면서, 스팸 메일이라고 불리 우는 광고성 메일이 무분별하게 전자우편에 침입하고 있다. 요즘과 같이 정보의 중요성과 개인의 사생활이 강조되는 시점에서 다른 사람이 중간에 메일을 가로채어 읽거나 해킹 하여 전혀 다른 내용으로 바꾸어 배포하거나 바뀐 내용을 전송하거나 과도한 스팸메일 때문에 자신의 메일 계정에 부하가 걸려서 중용한 메일을 못 받게 된다면 보통 심각한 일이 아닐 수 없다. 본 논문에서는 이것을 해결하기 위하여, PGP(Pretty Good Privacy)라는 기술과 문자열 처리를 이용하여 전자우편의 보안성 향상과 문자열 처리를 통해 스팸메일을 줄이는 방법을 제안한다.

E-mail service has been a general method for communication as internet is widely used instead of post mails. Many companies have invested in e-mail advertisement as e-mail service is spread. E-mail advertisement has an advantage that it can consider personal characters. A lot of e-mail users have been given e-mails that they did not want to receive because their e-mail addresses were opened out to companies on internet. Therefore, they need junk mail checking systems and several e-mail service providers have supported junk mail filters. However, the junk mail filters can check the junk mail with constraint because they don't check the junk degree of mails by the contents of e-mail. This paper suggests a content-based junk mail checking model using fuzzy relational products. The process of the junk mail checking model using fuzzy relational products is as following: (1) analyzes semantic relation between junk words-base and e-mails, (2) checks the junk degree of the e-mail using the semantic relation, (3) checks the mails with SVJ(Standard Value of Junk) if those are junk mail or non-junk mail. The efficiency of the proposed technique is proved by comparing the junk degree of the e-mail and the number of junk mails that was checked by e-mail users and checked by the proposed junk mail checking model.
