Cloud computing is an important part of the development of smart cities and also the focus of the information and communication technology (ICT) industry. From the concept of cloud computing, people and objects in cities are organized based on their application needs and computed in real time. It is a comprehensive utilization of the new generation of information and communication technology. This paper first introduces the concept of cloud computing, smart city construction in Taiwan, and the information security management standard of cloud computing, then describes the cloud computing security framework from three areas,and summarizes the implementation status of cloud computing in Taiwan, government policies, and measures, reaching the conclusion that information transmission must be fast and reliable and ensure personal privacy and security. Any type of information security problem will bring catastrophic consequences. Therefore, cloud computing also brings severe challenges to the traditional information security system.

Abstract. Here, we propose a time-dependent probabilistic seismic hazard assessment and apply it to Hualien City, Taiwan. A declustering catalog from 1940 to 2005 was used to build up a long-term seismicity rate model using a smoothing Kernel function. We also evaluated short-term seismicity rate perturbations according to the rate-and-state friction model, and the Coulomb stress changes imparted by earthquakes from 2006 to 2010. We assessed both long-term and short-term probabilistic seismic hazards by considering ground motion prediction equations for crustal and subduction earthquakes. The long-term seismic hazard in Hualien City gave a PGA (peak ground acceleration) of 0.46 g for the 2.1‰ annual exceedance probability. The result is similar to the levels determined in previous studies. Seismic hazards were significantly elevated following the 2007 ML =5.8 earthquake that occurred approximately 10 km from Hualien City. This work presents an assessment of a suitable mechanism for time-dependent probabilistic seismic hazard determinations using an updated earthquake catalog. Using minor model assumptions, our approach provides a suitable basis for rapid re-evaluations and will benefit decision-makers and public officials regarding seismic hazard mitigation.
