Managing cities efficiently requires a great combination of top-down and bottom-up ICT-enabled methodologies in order to make the city governance a complex phenomenon. To develop the Smart City solutions, the upgrading of a major source of urban, socio-economic and environmental data needs to be considered. This builds the notion of Smart Cities a huge momentum and attracts the researchers to work on this issue in the past decade. From the administrator’s point of view, the ICT potentially collects and processes the city data to aim for secure effectiveness and efficient city planning, decision making, and smart governance. We understand that, the developing innovative domain-specific applications to access the urban data and administrate the city with the help of Smart devices is a challenging task. There arises a strict need for privacy and security issues to be handled by the administration. We suggest the studies to ensuring the security which gives various benefits, such as uninterrupted smart governance, authentication and ensuring security with the potential help of high-performance computing paradigms like cloud computing enrich the Big Data management approaches to provide the smart governance.
