Mobile environment is relatively free from time and space constraints, and has unique characteristics such as not applying physical and social vulnerability because of it's non-face-to-face channel. Since such spatial and temporal speciality is likely to appear in a different form from psychological action and action in a general face-to-face environment, it is necessary to conduct an empirical study based on the results of the existing research that has been studied as major psychological variables of action in mobile environment. However, advance research have not been conducted in earnest on the vulnerability and anxiety of the consumers in a new environment called mobile finance. so this study intends to establish the basis through empirical research. As a result, women among traditional vulnerable groups perceived themselves to be vulnerable in mobile financial environments than men and felt fear of crime strongly. In addition, the vulnerability of mobile financial crime did not have a significant direct effect on mobile financial use, but it was confirmed that mobile crime fear was mediated completely and had an indirect effect on mobile financial use.

모바일 인스턴트 메신저에 적용된 암호기술은 사용자들의 개인정보를 보호하는 역할을 한다. 메신저에 저장된 사용자의 개인정보는 일반적으로 사용자의 패스워드, 사용자 정보 및 기기 정보 기반으로 생성된 암호화 키를 통해 암호화되므로 높은 안전성을 갖는다. 이러한 암호기술의 특성 때문에 국가 법집행기관은 범죄단서 확보 및 사실 증명을 위한 증거 분석과정에 어려움을 겪는다. 그러나, 최근 모바일 인스턴트 메신저를 통해 발생하고 있는 일련의 범죄 사건들을 볼 때 정당한 접근 하에 범죄단서 확보를 위한 암호분석 기술은 활발히 연구될 필요가 있다. 본 논문에서는 10종의 모바일 인스턴트 메신저에 대한 TMTO 및 GAN 모델을 활용한 안전성 분석을 제시한다.

Using the mobile device, such as Smartphones tablet PC, online banking and e-commerce, as well as process and to their work. While going to high availability and convenience of mobile devices castle, SNS, letters, using an email Smishing financial fraud and leakage of personal information such as crime has occurred many. Smishing smartphone accidents increased sharply from 2013, MERS infection cases, landmine provocative events, such as the delivery of Thanksgiving has occurred cleverly using social engineering techniques. In this paper, i analyze the trends in Smishing hacking attacks on mobile devices since 2014. With regard to social issues, it analyzes the process of hacking attacks Smishing leading to financial fraud to mobile users. And, in this paper, i propose a secure way and measures of financial damage for mobile Smishing hacking.

It is necessary to deploy blocking programs for detecting SMS phishing attacks in advance to do this. In this paper we are investigating the process of block types and block apps that are currently deployed and presenting the evaluation of the application of the detection block setting app.
