사람들의 욕구가 인터넷에 반영되면서 텍스트로 이루어져있는 인터넷 컨턴츠들이 이제는 멀티미디어로 이루어지고 있다. 사람들이 가장 많이 사용하고 있는 이메일 또한 이런 욕구가 반영되었다. 이젠 이메일도 멀티미디어 시대이다. 이메일의 장점을 이용해서 마케팅을 해오던 회사들도 텍스트가 아니라 멀티미디어로 사람들의 시선을 잡고자 한다. 기업의 마케팅 메일은 이메일을 사용하는 사용자 입장에서 본다면 스팸 메일이다. 많은 이메일 서비스 업체는 이런 스팸 메일을 차단하기 위해서 끈임없는 노력을 하고 있으며 많은 성과를 이뤘다. 현재는 과거의 방법으로 스팸 메일을 차단할 수 없기 때문에 새로운 방법이 모색되고 있다. 본 논문에서는 멀티미디어 스팸 메일 차단에 한 방법으로 MPEG-7를 이용한 MEMC(Multimedia E-Mail Classifictaion)을 제안한다.

이메일 스팸메일의 대부분은 악성코드에 감염된 좀비PC에 의해 발송된다. '11년 시만텍 보고서에 따르면 한국발 좀비PC에 의한 스팸메일 발송이 세계 1위를 차지했으며, '12년에도 상위수준을 유지하고 있다. 본 논문에서는 이메일의 패턴 분석을 통해 좀비PC 및 같은 공격명령을 받은 봇넷그룹을 자동으로 탐지하는 시스템을 개발하고, 이를 통해 산출된 다양한 데이터에 대한 분석결과를 제시한다. 좀비PC 및 봇넷그룹 탐지결과는 스팸메일 차단기술로 활용 가능할 뿐 아니라, 악성코드 유포동향 파악 등 다양한 목적의 분석에 활용 가능하다.

현재 인터넷 서비스 중에서 가장 많이 사용되는 서비스는 이메일이다. 본 연구에서는 POP3로부터 전송받은 이메일 메시지와 HTTP를 통해 접속한 웹메일 시스템의 이메일 메시지를 분석하여 제목, 보낸이, 본문 메시지와 특정 첨부파일을 분리해낸 후 USB에 연결된 아바타 로봇시스템에 전송 및 재생하는 시스템을 설계 및 구현하였다. 텍스트 메시지는 음성 변환 모듈을 통해 음성 파일로 변환하여 전송하게 되고, 특정 확장자의 첨부 파일은 바로 전송된다.

E-mail has indeed developed from 'a means of instant communication' to an indispensable part of online marketing. Therefore, companies need to implement consistent customer management. Communication with customers and marketing through e-mail is a powerful way of communication and adapting one-to-one marketing strategies to customer trends, habits and taste preferences. Since setting accurate targets is especially important in the fashion industry, e-mail marketing is the most effective way to communicate with customers and one-to-one marketing constitutes a very important strategy. In this study, I will analyze this powerful one-on-one marketing tool, particularly actual e-mail messages sent by an Internet Shopping Mall from June 12 to July 30, 2005, examine the effect of these messages on sales growth and analyze actual feedback received. Regarding e-mail read rates broken down by age and gender, 1 found that females in their late twenties recorded the highest rate at 21.66% and their contribution to sales growth was recorded at 3.5% From actual sales records, found that 28.10% of total sales were attributable to people in their late twenties, showing that the age group that reads e-mails the most also buys the most. Regarding feedback by e-mail title, e-mails from the 'Casual' category seemed to be the most effective, in that most of these e-mails were read. Also, messages sent on Tuesdays were read the most, according to the feedback analysis by weekday. Section e-mails were read more often than regular e-mails. Regarding the view rate according to the time e-mails were sent, messages sent to females in their late twenties at two o'clock in the afternoon were read by 20.93% of recipients, recording the highest read rate. By offering informative content and practical tips, visitors will be attracted to the site and generate site traffic. Therefore, we can conclude that sending e-mail messages can greatly contribute to sales growth and e-mail marketing is very effective. Also, in order to make e-mail campaigns more effective and improve marketing results, we need to analyze actual results and apply our findings in future e-mail campaigns. With this, we get successful marketing results.

Most cyber breaches are caused by APT attacks using malware. Hackers use the email system as a medium to penetrate the target. It uses e-mail as a method to access internally, destroys databases using long-term collected vulnerabilities, and illegally acquires personal information through system operation and ransomware. As such, the e-mail system is the most friendly and convenient, but at the same time operates in a blind spot of security. As a result, personal information leakage accidents can cause great damage to the company and society as a whole. This study intends to suggest an effective methodology to securely manage the APT attack by strengthening the security configuration of the e-mail system operating in the enterprise.

The implementation of cellular phone based applications have been growing very fast because of WIPI which is a hardware independent platform. In this paper, we design and Implement a system to combine the animation avatar and e-mail service by using WIPI platform. Also, this system manages scheduling at the same time. This system uses SMS service in order to notify scheduled time and it synchronizes the schedule data with Outlook Express on the computer.

Since the amount of E-mail messages has increased , we need a new technique for efficient e-mail classification. E-mail classifications are grouped into two classes: binary classification, multi-classification. The current binary classification methods are mostly spm mail classification methods which are based on rule driven, bayesian, SVM, etc. The current multi- classification methods are based on clustering which groups e-mails by similarity. In this paper, we propose a novel method for e-mail classification. It combines the automatic category generation method based on the vector model and the dynamic category hierarchy construction method. This method can multi-classify e-mail automatically and manage a large amount of e-mail efficiently. In addition, this method increases the search accuracy by dynamic reclassification of e-mails.

Recently Internet portals contend with each other to expand their customer base by providing customers with a much amount of e-mail storage. But This strategy may not be successful because of customers' switching cost following site moving. Therefore, in order to reveal whether their strategy makes sense, this study investigates the direct and contingency factors affecting customer switching intension of e-mail services in portal sites. The research results show that attractiveness of alternatives, switching cost, and customer satisfaction have a significantly direct impact on customer switching intension of e-mail services. Also, attractiveness of alternatives alone has an moderated effect on customer switching intension but switching cost does not. Thus, Internet portals may reap the harvest from their recent aggressive action.

In this paper, we propose an improved Bayesian Filtering mechanism to reduce the False Positives that occurs in the existing Bayesian Filtering mechanism. In the existing Bayesian Filtering mechanism, the same Bayesian Filtering DB trained at the e-mail server is applied to each e-mail user. Also, the training method using receiving e-mails only could not provide the high quality of ham DB. Due to these problems, the existing Bayesian Filtering mechanism can produce the False Positives which misclassify the ham e-mails into the spam e-mails. In the proposed mechanism, the sending e-mails of the user are treated as the high quality of ham information, and are trained to the Bayesian ham DB automatically. In addition, by providing a different Bayesian DB to each e-mail user respectively, more efficient e-mail filtering service is possible. Our experiments show the improvement of filtering accuracy by 3.13%, compared to the existing Bayesian Filtering mechanism.
