Recently, KakaoTalk users seek secure messengers with fears of 'possible' censorship over a mobile messenger. Instead German messenger "Telegram" is gaining popularity in South Korea. Are the known as secure messengers actually secure? In this paper, we evaluate secure mobile messengers in terms of private information protection. We establish the fourteen criteria to evaluate the functionality of messenger apps including communication encryption in transit, the possibility of leakage of decrypted messages via server, an encryption algorithm, a key exchange algorithm, an ephemeral message application, etc. Line, Telegram, Snapchat, WhatsApp, Wickr, Facebook Messenger and KakaoTalk, which have many worldwide and domestic users, are to be targeted. Wickr is ranked at the top of the evaluation, followed by Telegram and Line but KakaoTalk and Snapchat are ranked at the bottom of the evaluation list.

기존 Window8 Style 에 대한 디지털 포렌식 연구는 윈도우 기본 애플리케이션에 대해서만 진행되어 있는 상황이고, 다른 3rd party Style App 들에 대해서만 진행되어있는 상황이다. 본 논문에서는 Window8 Style UI 의 Instant Messengers 에 대해 디지털 포렌식 분석하고 이를 통해 범인의 행동 흐름 파악 및 증거확보 매커니즘을 제시하고자 한다. 본 논문은 기존의 Window8 의 접근방법을 토대로 하여, Style App 의 사용흔적이나 내용에 대해 확인하며, 시간정보, 이미지 등 각종 애플리케이션들을 다각적으로 분석한다. 본 논문에서 제안한 접근법은 개별 App 들에 대한 정보를 효율적이고 빠르게 분석하고 사건에 대한 정보를 제공함으로써 범죄수사과정에 도움이 될 것으로 기대된다.

대중화된 소셜 네트워크 환경에서 사용자가 제작한 콘텐츠를 빠르고 간편하게 공유할 수 있도록 하는 모바일 App을 개발하였다. 기존 사용자 영상 콘텐츠 제작 환경에서는 필요 이상의 소음과 잡음이 혼재하여 영상에서 풍기는 이미지의 감동을 저해하고 있다. 이러한 주의의 소음과 잡음으로부터 영상을 보호하도록 배경음악을 영상과 함께 재생하여 영상의 감동과 느낌을 사용자에게 전달하기 위한 App이다. 또한 소셜 네트워크 환경에 간편하게 업로드 할 수 있도록 페이스북을 통해 다른 사용자와 빠른 공유를 할 수 있다.

We develop a smart tourism information system that provides smart tourism services to free independent tourists (FITs) through various content distribution channels such as mobile apps, Instagram, YouTube, and chatbots. The smart tourism information system provides location and storytelling-based tourism information, accommodation, restaurant information, and recommended travel products so that tourists can create a travel itinerary based on personalized situation awareness. The smart tourism information system also provides smart tourism services using commercial maps, navigation, and weather forecast APIs from the Korea Meteorological Administration to provide smart tour guide services to tourists who travel according to the travel itinerary. In this paper, we develop the React Native app that provides smart tourism services provided by the smart tourism information system. The smart tourism React Native app has implemented two methods: a method that directly connects to the smart tourism information system, and a method that provides services by interworking through the GraphQL Query Language developed by META (Facebook). The smart tourism React Native app implements OSMU (One Source Multi-use) by providing tourism information from mobile apps, photos from Instagram, and drone videos from YouTube as an integrated UI.

Customized service is a vital and mandatory element for apps in improving their technical performance and app customer analysis. While apps require users' consent for their data extraction and usage, many of the terms and agreement forms are written intricately, making it harder for users to fully understand the whole concept of users' data collection for customized services. Ever since the Facebook-Cambridge Analytica scandal, personal data privacy has been re-examined, forcing many app companies to reinforce a reliable solution to data privacy issues. However, there has not been a secured solution, which worries many people about the future advanced issues when metaverse platforms are actively used in daily apps. The research aims to collect the reactions and behaviors of everyday app users who utilize apps with customized services to understand the nature of privacy data issues and the users' opinions about the future implementation of metaverse platforms. The method of the research was an online questionnaire that targeted university students. The study revealed many fearful and anxious reactions about personal data and further metaverse issues where most app users were uneducated about how current apps collect and utilize users' private data.

Despite the increasing adoption of gamification and its huge potential in tourism, research in gamification is still limited. As preliminary findings show that the effectiveness of gamification depends on the context of its application and the players' use of the gamified app, this paper fills in these gaps: by exploring and analysing the application of gamification in a specific e-commerce tourism context; and assessing the gamification's effectiveness by measuring the players' gamification usage and the latter's behavioural and psychological outcomes. The gamified TripAdvisor website and its Facebook enabled gamification app are used as the specific context of the study. Findings from a survey conducted on TripAdvisor users provide useful practical and theoretical implications to gamification designers and researchers alike on how game mechanics can be designed for enhancing the users' motivation, flow, task involvement and engagement with the 'play' tasks, and so, increasing the gamification's effectiveness.
