## 4 Results
### Reliability Analysis  
Table 4 analyzes the reliability of respondents for each construct. Reliability analysis was performed with SPSS version 20 (Seoul, Korea) to confirm the reliability of the questionnaire response, and it was confirmed that the reliability of the response was secured with a Chronbach \(\alpha\) value of 0.7 or higher [33]. The minimum value of the Chronbach \(\alpha\) value for the measurement variables of each component is 0.713 for information reliability, and the maximum value for the security threat is 0.927, so it can be said that the response is reliable.
