However, smartphone usage popularized research to protect sensitive information, such as smart phone users personal information, financial information is a small state. In this paper, we analyzed the various vulnerabilities in smartphone studies to date have been looking into the corresponding port smart consumer dispute resolution methods and criteria for smartphone security attack methods and analysis. In particular, the threat of such a network, malware, Peep attack of the security threats arising from the smartphone they can avoid or mitigate threats to minimize the smartphone security damage is done to the disclosure of personal information, such as direct damage or financial loss the analysis of that method.

This study investigates the effects of sociality, life stress, and depression on smartphone addiction among nursing college students. In October and November 2019, data was collected from nursing college students situated in certain areas. The data of totally 270 students was finally analyzed by frequency, percentage, t-test, and ANOVA, to examine differences in smartphone addiction according to the general characteristics of the subjects. Major variables and multiple regression analysis was carried out to examine factors influencing smartphone addiction. We determined that hours of using a smartphone (β=0.183, p<0.001), life stress (β=0.369, p<0.001), and depression (β=0.205, p=0.012) significantly affect smartphone addiction, having an explanatory power of 33.5%. Life stress (r=0.50, p<0.001) and depression (r=0.35, p<0.001) have high positive correlations with smartphone addiction, whereas sociality (r=-0.20, p<0.001) is negatively correlated. To summarize, our results indicate that hours of using a smartphone, life stress, and depression have important impacts on smartphone addiction among nursing college students. These findings raise a need to reinforce the development of programs to help nursing college students increase their ability of managing hours of using a smartphone, and reduce their life stress and depression to prevent subsequent smartphone addiction.

Recently, as the number of smartphone users has been increasing worldwide, various services such as electronic payment, internet use, and financial settlement are being used as a smartphone. In addition, researches for home appliance control and automobile control using smartphone are conducted. As such, smartphone users can enjoy a more convenient life, but by hacking smartphones, tapping texts and conversations on smartphones, tracking location through spy apps, DDoS attacks using smartphones, and malicious apps When a message is received at a specific telephone number when using a micropayment, the corresponding text message is transmitted to a remote server, thereby increasing the risk of leakage of personal information and the like. Therefore, in this paper, we define the risk factors of the smartphone that are caused by the internal and external environmental, physical, contents (apps) of the smartphone through the smartphone that we use in real life, We propose a method to check vulnerability of smartphone security solution such as CC evaluation and the most effective response technique for each risk of smartphone by defining the technique.
