An Empirical Study on a Tradeoff between Security and Convenience: The Case of i-PIN System

The resident registration numbers were used for administrative purposes including people's up-to-date residence information and vital statistics or provision of public services in Korea. In 2005, the government of Korea devised the i-PIN, a new online personal identification system replacing resident registration numbers. In the context of the i-PIN, the present study intended to shed light on the relationship between security and convenience. Also, we tried to explore the antecedents of adoption of the i-PIN. As a result, user support and perceived security had positive effects on the perceived ease of use, perceived usefulness respectively. The perceived ease of use also had significant effects on the perceived usefulness and satisfaction, whereas it did not exert direct effects on the use intention. Not surprisingly, the most significant variable influencing the use intention and satisfaction was perceived usefulness.
