Description
With the development of IoT technology, a large number of IoT devices and new applications are expected to emerge, generating a large amount of data. These data include spatio-temporal data (STD), which is needed only at a specific time and place. In our previous research, we proposed a spatio-temporal data retention system (STD-RS) using vehicles, aiming to construct a new network that keeps spatio-temporal data in a specific period and range. However, when STD-RS is operated in real space, there is a possibility that STD is transmitted outside the target range due to malfunctions caused by errors in location information, reception signal strength, bugs in software programs, etc. As a service provider using STD-RS, it is important to ensure the reliability of the provided range. In this paper, we propose a new method for the transmission of STD-RS. In this paper, we propose a multi-layered blockchain as a mechanism to audit STD-RS in the upper layer while the lower layer manages the STD generated from the real space. In order to achieve real-time auditing of STD-RS, it is important to reduce the block search time.
