Distributing information on the internet is common in our daily life. In the past, e-mail has been the primary choice of exchanging information. But instant messengers are gaining popularity abroad and domestically because of their immediate responses. Instant messaging has become the fastest growing communication technology in recent years. Instant messaging is effectively a chat room of two people. Users that have accounts with the same provider are able to send messages via computer in real time. Instant messaging has exploded into the business world as companies utilize the technology for everything from interoffice communication to client/customer communication. In this paper, we propose a system design for effective data collection and statistical analysis.

Purpose: The Purposes of this study are (1) to examine why users are communicating through MIM (2) to understand what factors impact these users' satisfaction and loyalty. Methods: We use a questionnaire survey to collect 256 data on users' perceptions of Kakaotalk. We also use a structural equation modeling method by using AMOS 18.0. Results: Company trust, communication voice, connectedness, and perceived network size are found to be statistically significant factors affecting. Also, satisfaction influence on word of mouth and intention to switch. Conclusion: This study develops a research model from the MIM context. We suggest three points of view as company characteristics, device interactivity, and social factor. We examine the determinants of users' satisfaction and loyalty. The results can offer valuable insights for future mobile services research.

This study is to understand the inner psychological state of consumers who pursue a retail therapy effect through fashion product shopping. Qualitative research on the whole process from the point of time of occurrence of shopping motivation to the end of shopping motivation was performed. The researcher became a virtual shopping partner during shopping and conducted a natural conversation interview using a mobile instant messenger program (Kakao Talk). After shopping, participants were asked to write a diary on that day. Collected data were analyzed by applying the grounded theory approach suggested by Strauss and Corbin (1998). Casual Condition, represented everyday stress and Contextual Condition indicated the self-healing consumption trend. Main Phenomena showed a mood change during the fashion shopping process. The sense of emancipation from the place, the satisfaction from the maintenance of social relations, and the sense of accomplishment through purchases were revealed. Intervening Condition showed the consideration in the process of shopping for fashion products, such as providing a try-on experience, price promotion, and involvement of a companion. Action Interaction Strategy was the shopping behavior for the positive emotion increase and negative emotion decrease. Consequence represented a retail therapy in shopping for fashion products.

This paper outlines the concept of real time reference service(RTRS). Then, it analyzes real time reference service in the 13 libraries for effective reference service. As a result, the most used software was AOL instant Messenger, followed by Conference Room from WebMaster, and LivePerson. Hours of service was generally same as reference desk hours. The users were Students. faculty, staff, and alumni, This study also demonstrated how the RTRS in LC works. The results showed that real time reference was able to response to patrons quickly for reference questions with interactive method.

In this paper, we propose an emotion messenger which recognizes face or hand gestures of a user using a WebCAM, converts recognized emotions (joy, anger, grief, happiness) to flash-cones, and transmits them to the counterpart. This messenger consists of face recognition module, hand gesture recognition module, and messenger module. In the face recognition module, it converts each region of the eye and the mouth to a binary image and recognizes wink, kiss, and yawn according to shape change of the eye and the mouth. In hand gesture recognition module, it recognizes gawi-bawi-bo according to the number of fingers it has recognized. In messenger module, it converts wink, kiss, and yawn recognized by the face recognition module and gawi-bawi-bo recognized by the hand gesture recognition module to flash-cones and transmits them to the counterpart. Through simulation, we confirmed that CPU share ratio of the emotion messenger is minimized. Moreover, with respect to recognition ratio, we show that the hand gesture recognition module performs better than the face recognition module.

With the increase in smartphone user, mobile forensics has become an essential element in modern digital forensic investigation. Mobile messenger data is very important data in mobile forensics because it can acquire information such as user's life pattern and mental state. In order to analyze messenger data, a decryption technique of an encrypted messenger data is required. Since most messengers provide a message deleting function, a technique for recovering deleted messages is required. WeChat Messenger, a messenger used by about 1 billion people around the world, uses IMEI (International Mobile Equipment Identity) information to encrypt data and provides message deletion function. In this paper, we propose a data decryption method in the absence of IMEI information and propose a method for recovering deleted messages using FTS (Full Text Search) database created for full-text search function of SQLite database.

Mobile network has become an essential tool for mutual communications, so a survey research published that most of the smartphone users use Mobile Instant Messenger every day. In this paper, we developed a wire-wireless integrated web messenger that can be used in various platform of mobile devices and desktop computer for communicating between users of some companies. We defined a multi-organization as several independent companies. Our web messenger was developed for communicating of users of a multi-organization. So one of functions of our web messenger is to restrict access to some particular departments in each company for the security of their company. Developed web messenger worked reliably from variety of web browsers on most of platforms such as android, iOs and desktop computers.

Recently, the investigation has been difficult due to the emergence of messengers that encrypt and store data for the purpose of protecting personal information and provide services such as end-to-end encryption with a focus on security. Accordingly, the number of crime cases using security messengers is increasing, but research on data decoding for security messengers is needed. Element security messengers provide end-to-end encryption functions so that only conversation participants can check conversation history, but research on decoding them is insufficient. Therefore, in this paper, we analyze the instant messenger Element, which provides end-to-end encryption, and propose a plaintext verification of the history of encrypted secure chat rooms using decryption keys stored in the Windows Credential Manager service without user passwords. In addition, we summarize the results of analyzing significant general and secure chat-related artifacts from a digital forensics investigation perspective.

A policy of instant messaging usage is offered in this article. First, a brief introduction of instant messaging system structure is described. The main threats and vulnerabilities of Instant messenger (IM) are described in the second part of the paper. Instant messaging applications offer so many advantages in so many different fields that they're fast becoming the preferred communication tool for a number of different professional scenarios. When properly implemented, instant messaging can be a true asset to the business by making communications easier throughout the organization. If instant messaging is carelessly implemented, though, it can cause problems with privacy and may expose the organization to various forms of malware. The solution offered in this paper is one of the effective ways against threats of IM. However, the system cannot be secured entirely. All we can do is reducing the risks.
