  • Thumbnail, the small sized graphic file such as JPEG or GIF, serves to help the users to be recognized as a rapidly helps to make it easier recognize while browsing the large sized graphic file. Gallery application, which is installed in a later version of the 4.4.x(Kitkat) Android smartphone records the generated time of graphic file in thumbnail metadata. Thumbnail can be used to draw up the timeline of user action about user's action such as creation, modification, deletion with original graphic file analysis. Also, take advantage of the features thumbnails are stored sequentially in a single thumbcache file, even if the thumbcache is deleted, we can restore the thumbnails. This paper illustrates the feature of thumbnail created by Android OS basic gallery app and methods for utilization in digital forensics.

  • 최근 들어 정부의 적극적인 지원책에 힘입어 전통적인 축산농장의 환경을 스마트 축사로 개선하는 사업이 다양하게 추진되고 있다. 이에 축산농장의 스마트화를 위해 다양한 축산용 ICT 기기들이 개발되어 도입되고 있고, 클라우드기반의 인터넷환경까지 연결되고 있으나, 이러한 ICT 기기들을 사용하여 스마트 축사를 구축하고 운영하는데, 편의성 측면에서나 효율성 측면에서 어려움을 겪는 경우가 다수 발생하고 있다. 이 문제를 해결하기 위해, 축산 현장에서 사용자의 편의성 측면을 고려하여 축산현장 정보를 기록하는 스마트 블랙박스 시스템을 개발하고, 효율성을 고려하여 이 시스템을 위한 지능형 시스템 관제 플랫폼을 개발하였다. 그리고 현장상황에서 실증평가를 통해 축산 인들이 현장에서 축산 ICT 기기를 쉽고, 안전하게 운영하도록 하도록 사용자 환경을 구축하였다. 본 논문에서는 개발된 스마트 축산 ICT 블랙박스 시스템(Smart.Dx)과 IoT센서 수집용 게이트웨이(Smart.Dn), 그리고 클라우드 데이터 분석 솔루션(Smart.Center)을 기술한다. 이 연구내용은 또한 축산업에 종사하는 고령자나 스마트폰 환경에 익숙하지 않은 사용자 환경 특성을 고려하여, 유니버셜 디자인의 7대 원칙을 지원하고 있다.

  • Recently smartphones, tablet, etc. Various types of smart terminal is due to the increased security in mobile devices are becoming an issue. How to enter the password in this environment is a very important issue. Difficult to have a secure password input device on various types of mobile devices. In addition you enter on the touch screen the password of character, uncomfortable and it is vulnerable to SSA attack. Therefore, in this paper provide for defense the SSA(Shoulder Surfing Attacks) and useful password input mechanism is proposed with Smartphone GPS uses a value generated via a graphical password techniques.

  • The paper describes the efficient and agile design methodology for the smart phone application, so called the App. Despite the number of smart phones as well as their applications is rapidly being increased recently, the smart and easy methodology for App development is not well developed and not matured in use yet. Since the App is converted to programs or contents from the new ideas, especially, it is important to design and implement the App rapidly and systematically. In order to resolve this problem, we adopt the UI centered approach first of all, emphasizing user-efficient utilization of applications. And we also try to build the whole process in streamlined procedure, making each step reasonable, and the input and output for the step well organized. The design methodology described here is evaluated by designing popular sample application, Scheduler, and also compared with some well-known software design methodologies.

  • This research focuses on the relationship between influencing factors of users' smartphone application download and consumers' purchase. The results show that there is some difference between them. The factors influencing mobile application download include word of mouth, usability, ease of use, functionality, enjoyment, interoperability, design, and experience while the factors influencing purchase are word of mouth, usability, ease of use, cost, functionality, enjoyment, interoperability, design, experience. An experience factor impacts on both download and purchase. Specially, enjoyment, usability, and functionality have strong effects on purchase. We also found out that mobile application type such as hedonic or utilitarian application also impacts on purchasing application. For utilitarian application, functionality impacts on purchase intension. Therefore this fact suggests that it is very important to understand the accurate purchasing influence of its consumer when setting up the marketing strategy of mobile application.

  • Recently, the development of smart devices such as smart phones and tablet PCs, with mobility, convenience and real-time computing, promotes proliferation and activation of social media. It also causes innovative changes in communication methods. Since 2010, researches in SNS (Social Networking Services) have focused on developing marketing strategies using SNS. On the other hand, the main purpose of this study is to provide a requirement analysis method of smart phone users by using content analysis of SNS. An information systems developed in this study in order to analyze content of SNS automatically because it is very difficult and time consuming to analyze it manually. In addition, this study compares the result of content analysis with that of Kano survey in order to examine consistency between the two results.

  • Most smartphone use virtual keypads based on touch-pad. The virtual keypads often make typographical errors because of the physical limitations of device such as small screen and limited input methods. To resolve this problem, many similar word-finding methods have been studied. In the paper, we propose an edit distance method (a well-known string similarity measure) that is modified to consider various types of virtual keypads. The proposed method effectively covers typographical errors in various keypads by converting an input string into a physical key sequence and by reflecting characteristics of virtual keypads to edit scores. In the experiments with various keypads, the proposed method showed better performances than a typical edit distance method.

  • According to rapid advent of the smartphone, software technologies which have been used on PCs are being introduced into the smartphone. This paper introduces an implementation of an application software under the Android platform using morphing and warping technology. It composes two face images with morphing technology and also transforms an original face image using warping technology for fun. For this, the image is triangulated by Delaunay Triangulation based on control points which are created by simple LCD touches on the mobile device. The implementation case of this paper will be a good reference for the development of applications like games using morphing and warping technologies over Android platforms.
