Study on Security and Privacy of E-Government Service

In the big data era, a shift from an existing provider-oriented e-government to a user-centered digital government is required. It is time to implement a consumer-centered digital government that can proactively provide customized services to the public rather than services that meet the public’s eye. This study analyzed prior studies and cases of e-government in order to derive the factors influencing the continuous use of e-government services provided by central government departments, local governments and public institutions, and to establish the causal relationship between each factor. Moreover, based on the information system success model and the technology acceptance model, the empirical analysis was used to determine how concerns about quality and privacy of e-government services and security affect usability, user satisfaction, and willingness to use them continuously. This contributed to presenting the policy direction and implications to the e-government in the contemporary paradigm of new IT and the fourth industrial revolution.
