Abstract: As sensor devices become diverse and prices fall, we develop diverse systems that use sensors. The integrity of the data used is critical to the value of these systems. A system using data generated at a sensor device must be able to obtain reliable data from the sensor device. They are design/develop general sensor devices for their purpose and their functions are limited. In order to overcome the limitation of performance of the sensor device, a collector node located in the local area and a Blockchain for ensuring the integrity are used. This is to increase the value of the system. When data of a sensor device located at a remote site is used, it is difficult to guarantee the integrity of the transmitted data. In this paper, we use a Blockchain as a method to store data and a collector node to manage the sensor device and to secure the integrity of data. It manages the data generated by the sensor node through the collector node and calculates the hash value to ensure the reliability of the data. Through the nodes constituting the block-chain, the node records the computed hash value in the block. When using data in the main system server, the integrity of the data can check using the hash value stored in the block-chain, and the reliability of the system can increase. This paper presents a method for securing data reliability by using a collector node and a Blockchain when generating in a sensor device However, the disadvantage of utilizing the data in the main system server according to the block generation rate is that it has a delay time. Future research will explore a Blockchain system suitable for sensor devices. Although this paper focuses on data generated in sensor devices, it can secure the reliability of objects by recording information such as digital documents and programs in a block-chain.
