With the increase in smartphone users, attacks targeting smartphone malware, zombie smartphone, such as smart phones is increasing. Security of smart phones is more vulnerable than PC security, for a zombie smartphone and generates a serious problem than the zombie PC attack on the smartphone every day is diversification. In this paper, the comparative analysis of malicious code and smartphone DDoS attacks and DDoS attacks from the PC, When using a service by connecting to the data network, proposes a method for users to confirm the packet smartphone direct a method for detecting by using the PC malware Smart PC Phone. Propose the measures of malicious code and smartphone DDoS attacks.

Traditional DDoS defence methods are performed at server side which was attacked. If servers detect DDoS attack, they use some methods for defending the attack such as increasing the bandwidth, bypassing the traffic, blocking the IP addresses or blocking the ports by the firewall. But as lots of people use smart-phones, it is possible a smart-phone to be a zombie and DDoS attack could be much more a huge and powerful forms than now. Victims are not only a server but also a host which becomes a zombie. While it performs DDoS attack, zombie smart-phone users have to pay the extra charge. After finish the attack, DDoS try to destroy hard drives of zombie hosts. Therefore the situation is changed rather than to defend DDoS server side only, we should protect a client side who needs to prevent DDoS attacks. In this paper, we study a defence method that we terminates a process which perform the attack, send the information to different hosts when a zombie PC or smart-phone perform DDoS attacks.

Smart phone zombie or Smombie means pedestrians who walk without attention to their surroundings because they are focused upon their smart phone. Because the traffic accidents and injuries caused by Smombie have been increased rapidly in recent years, the social attention and policies are needed to prevent it. This study was conducted to analyze Smombie's current status and some solutions used before and to propose new improved method through the latest ICT trend. In this study, we did the field survey to check Smombies at several places in Seoul through people counting, and found that a lot of pedestrians still use the smart phone while walking. And we analyzed many case studies about some solutions to prevent Smombies previously. The case studies include legal regulations, government policies, smart phone app services and facilities that are used before. We studied them through internet searches and reference studies and we also checked the current operating situation as visiting several places that the solutions actually has been operated. Therefore, we found there are some limitations in previous solutions in terms of effectiveness and management. To consider new solution that can be expected to overcome the limitations, we analyzed the latest ICT trends focused on features to utilize the Smombie prevention, especially video recognition and digital signage. In these days, video recognition has been developed rapidly with assistance of AI technology and it can recognize the specific pedestrian's characteristics such as holding smart phone as well as hair style, clothes, backpack and etc. On the other hands, the digital signage is the convergence device that includes big display, network connection and various IoT sensors. It can be used as public media in many places for public services as well as advertising. Through these analysis results, we show the requirements and the user scenario for the improved method to prevent Smombie. Finally, we propose to develop R&D technology to recognize Smombie exactly as pedestrian attributes and to spread creative contents to increase pedestrian's interest and engagement for Smombie prevention through digital signage.

In this paper, VR game was produced to inform the danger of using smartphone while walking and to raise awareness. In this VR games, you can experience Smombie (smart phone and zombie compound word) like a real situation by using Google card board and Bluetooth controller. Designed as a directions game of everyday material, the user indirectly experiences the dangerous situations that may actually occur in everyday life. In the virtual space, you can see the map on the smartphone, navigate the route, and send text messages using the controller during the game. We will explain how to implement smartphone map and send text message using controller which are the main functions of VR game.
