RFID에 대한 신뢰 및 인지된 위험의 영향

RFID has been bringing drastic changes to our economy, society, and culture as a core foundation technology of the Ubiquitous Sensor Network(USN). RFID is widely spread among the industries with the strong support of related institutions, but, we need to consider the negative side caused by the business information leak and privacy problems. This study presents an extended technology acceptance model (e-TAM) that integrates trust and perceived risk into the TAM to investigate the effect of trust and perceived risk on the TAM variables. This paper proposes trust as a 2nd-order latent construct consisting of 5 first-order factors; institutional trust, trust between companies, trust within company, technology trust, and service provider trust. The proposed model was empirically tested using data collected from employees in companies or Public Enterprises. The analysis results of this study can be summarized systematically as follows. (1) The survey result indicated that the trust indirectly affects to the attitude toward RFID by mediating perceived easy of use and perceived usefulness. (2) The survey result reveals that the RFID-related-trust decreases the perceived risk. It is also revealed that among 5 first-order factors of the trust, the service provider trust had the most significant influence. (3) Furthermore, a striking and somewhat puzzling finding was the positive influence of perceived risk on perceived usefulness. This phenomena indicates that the respondents highly perceives the usefulness of the technology in spite of perceiving the risk.
