Outline of Final Research Achievements	In this research, from the point of view of data mining and privacy preservation, we proposed a cloud architecture of traffic information system for location service platform. First, we had a survey research of data mining related to privacy preservation and spatial data processing. Next, using the open source HElib (Homomorphic Encryption library) of fully homomorphic encryption, we tried to implement a prototype system in the cloud. In near future, a further improvement in computer performance revealed to be a key technology data security enhancement in the cloud architecture.
