  • Recently, e-mail has become an important way of communications in IT societies, but it creates various social problems due to increase of spam mails. Even though many organizations and cooperation have been trying researches to develop spam mail blocking technologies, a lot of cost and system complexities are required because of varieties of spam blocking technologies. In this paper, we designed of the SMBC(Spam Mail Blocking Center) using the Fit FA(Filtering Algorithm) Finder. Fit-FA Finder that search and applises spam mail filtering algorithm of the most suitable confrontation according to type of spam mail. The system of spam mail filtering is decided performance of the system by procedure that spam filter is used. Go through designed Fit-FA Finder and reduced unnecessary filtering process and processing time and load than appointment order filter application way of existent spam mail interception system.

  • 인터넷이 발전함에 따라 기업의 업무, 커뮤니케이션 등이 온라인으로 전환되고 있으며, 정보전달의 통로로써 전자 메일의 사용이 나날이 늘고 있다. 이에 따라 전자 메일을 통한 바이러스, 스팸 광고 등 메일의 컨텐츠를 이용한 공격에 의한 피해가 심각한 수준에 이르고 있다. 현재 방지 대책으로는 백신이나 스팸 메일 차단기 등을 통해 방지 기능을 제공하고는 있으나 이는 사용자의 의지에 의존적이며, 개개 시스템에 한정되는 한계가 있다. 따라서 사용자의 의지와 무관하게 네트워크 차원에서 내부 네트워크를 보호하기 위한 방지 대책이 필요하며 이에 본 논문에서는 기존의 침입 탐지 시스템을 확장하여 메일 컨텐츠를 탐지할 수 있는 확장된 침입탐지 시스템을 제안한다.

  • In addition to RBL function, which is used to applying for spam e-mail filtering, as an effective way to deal with the recently widespread spam types, this paper proposes how to extract URL that was comprised in the original e-mail, apply it to RBL, and expand it. The BotNet, which is used to using for sending spam mails these days, has a problem that it is not able to solve with the distributed addresses of sent mails in spam e-mails. In general, as these spam e-mails are sent from the infected Zombi PC of individual user, the sent address itself is not efficient and is meaningless to use in RBL. As an effective way to filter spam e-mail sent by BotNet, this paper analyzes URLs that contained in the original spam e-mail and proposes how to effectively improve filter rate, based on the distribution data of URL site tempting users. This paper proposes the sending mechanism of spam e-mails from BotNet and the methods to realize those types of spam e-mails. In order to gather analyzable spam e-mails, this paper also carries out an experiment by configuring trap system of spam e-mail. By analyzing spam e-mails, which have been received during the certain period of experiment, this paper shows that the expanded RBL method, using URLs that contained in spam e-mails, is effective way to improve the filter distribution of spam e-mail.

  • 이메일 서비스 사용자들은 스패머가 무차별적으로 발송하는 스팸메일에 의한 정신적 경제적 피해를 입고 있다. 이러한 피해를 막기 위해 필터링, RBL (Real-time Blackhole List)과 같은 스팸차단 기법이 등장하였고 많은 메일서버에서 사용되고 있다. 그러나 이는 스팸메일의 근본적인 원인은 해결하지 못하며, 높은 차단율을 유지하기 위해서는 지속적인 관리 및 업데이트가 필요하다. 이러한 한계점을 극복하기 위한 기법으로 송신자 자가인증 기법이 있다. 본 논문에서는 송신자 자가인증 기법을 적용하여, 스팸메일을 근본적으로 차단하고 지속적인 업데이트가 필요 없는 스팸차단 서버 및 애플리케이션을 구현하였다.

  • 대출 광고에서부터 각종 이벤트 광고, 성인광고에 이르기까지 우리의 휴대전화와 이메일 박스는 종류도 다양한 스팸메일들을 수신하고 있습니다. 스팸은 결코 환영받지 못하는 손님이지만, 수많은 스팸으로 인해 사용자들은 오히려 스팸 수신을 당연한 것처럼 받아들이는 분위기로까지 이어지고 있습니다. 뭔가 크게 잘못되어 있는거죠. 지난달 29일 코엑스 그랜드볼룸에서 방송통신위원회와 KISA가 스팸 발송 사업자를 규제하기 위한 '2008 스팸방지 가이드라인 개정' 공청회를 개최한 것도 스팸과 관련한 사업자 대상의 강력한 규제를 단행하겠다는 의지가 반영돼 있습니다.

  • This paper presents a spam filter system using co-training with spamminess features and URL features based on the maximum entropy model. Spamminess features are the emphasizing patterns or abnormal patterns in spam messages used by spammers to express their intention and to avoid being filtered by the spam filter system. Since spammers use URLs to give the details and make a change to the URL format not to be filtered by the black list, normal and abnormal URLs can be key features to detect the spam messages. Co-training with spamminess features and URL features uses two different features which are independent each other in training. The filter system can learn information from them independently. Experiment results on TREC spam test collection shows that the proposed approach achieves 9.1% improvement and 6.9% improvement in accuracy compared to the base system and bogo filter system, respectively. The result analysis shows that the proposed spamminess features and URL features are helpful. And an experiment result of the co-training shows that two feature sets are useful since the number of training documents are reduced while the accuracy is closed to the batch learning.

  • Today, The much amount of spam that occupies the mail server and network storage occurs the lack of negative issues, such as overload, and for users to delete the spam should spend time, resources have a problem. Automatic spam filtering on the incidence to solve the problem is essential. A lot of Spam filters have tried to solve the problem emerged as an essential element automatically. Unlike traditional method such as Naive Bayesian, PCA through the many-dimensional data set of spam with a few spindle-dimensional process that narrowed the operation to reduce the burden on certain groups for classification Logistic regression analysis method was used to filter the spam. Through the speed and performance, it was able to get the positive results.

  • Electronic mail (E-mail) is an integral part of communication for the recent Internet users. However, e-mail has also come to serve as a means to support flood of unwanted spam mails and junk mails having bad purposes. This paper was conducted in order to develop an intelligent e-mail system using user behavior pattern that can prevent these unnecessary information and enable the user to enjoy communication via e-mail in a cleaner environment. The concentrated analysis of the user behavior in terms of using e-mail functions has resulted in better classification between unnecessary and necessary information, thereby facilitating faster disposal of spam mails.

  • 본 연구에서는 이메일 사용자별로 제공받은 사용자 선호 정보 대상으로 EM 클러스터링을 수행하여 사용자 클러스터를 만든 후, 사용자 클러스터들의 이메일 반응 분포를 계산함으로써 사용자 취향에 따라 동일한 이메일에 대해서도 서로 다른 반응을 가질 수 있다는 사실을 확인하려고 한다. 그 결과로부터 현재의 내용기반 방식과는 다르게 사용자 선호도를 고려한 스팸 메일 필터 구축 방법을 제안한다.

  • The conventional email method based on a recipient mailbox has a structural weakness, which may cause the spam message problem and the extreme waste of recipient mailbox space, and also require an explicit recipient notification scheme. This paper proposes a new email method based on a sender mailbox and evaluates its performance. Under the new email method, a message is stored at sender mailbox instead of recipient one until an intended recipient reads the message, so that the burden of mailbox management such as removing spam message is now shifted to sender side. And also a sender can confirm whether an intended recipient has read his or her message by simply rummaging his or her sender mailbox. The results of Performance evaluation show that 75% of mailbox space and 90% of message traffic are reduced in conditions that the portions of spam message and multicasting message are 90% and 80%, respectively.
