A safer way to share a car based on SNS to increase use efficiency of released vehicles

Due to rapid urbanization, a parking space in cities is very insufficient, and moreover, a use efficiency of released vehicles is greatly reduced. To solve such problems, a car sharing service has been introduced, but focuses on a service that overcomes limitations of rental cars. Our paper is focused on providing the safest car sharing service based on SNS(Social Networking Service) to increase a use efficiency of released vehicles. More particularly, a direct transaction between a car sharing service provider and a user can be provided. Therefore, it is not required to separately construct an infrastructure for the car sharing service. Our paper can be contributed to maximize the usability of the used car and to solve a problem which is lack of parking lots by using the cyber security mechanism.
