            As a result, asymmetric information causes inevitable distrust in economic transaction for used car through
            conflicting  motivation.  A  buyer  cannot  trust  in  sellers’  word  about  the  condition  of  the  vehicle.  While
            consumers  need  a  careful  investigation  in  order  to  avoid  purchasing  defective  vehicle,  they  are  not
            accustomed to investigate the car. Consequently, asymmetric information makes them fail to trust in sellers
            and used cars, so level of satisfaction is always threatened. A great number of articles have shown that trust
            is strongly related to satisfaction of various goods.
            In summary, as seen in Figure IV.12, the current used car transaction involves following inevitable problems;
            (1) asymmetric information, (2) conflicting motivation of disclosing the condition of used car due to (1), and
            (3) distrust among entities due to (2). Thus, an appropriate intervention is needed for avoiding dispute among
            entities and activating the used car market.

            In  order  to  overcome  sequential  problems  discussed,  it  is  direct  remedy  to  make  participants  share
            information. Trust management platform can play an important role in mediating entities who participate in
            used vehicle market and sharing trustful data and information (Figure IV.13).
            When a buyer request selling his/her car, a dealer registers that vehicle in an online market place liked to
            trust service broker. Then, trust management platform automatically collects data from various sources such
            as insurance company, public organization, social network services, and vehicle itself. If a vehicle owner
            attaches On-Board Diagnostics 2 (OBD2) scanner, this IoT device records and accumulates wide ranges of
            vehicle-oriented information such as driving distance, recorded fuel efficiency, accident, driving habits, and
            maintenance and repair history.

            In the next step, by transforming these fragmented data into single information, trust management platform
            identifies and evaluate the level of trust of an owner of used car, a registered vehicle, and a dealer. Based on
            this refined and trustful information, a buyer can assure the condition of the used vehicle prior to purchasing
            and make a purchase decision with comparably low level of uncertainty and risk.
