Abstract: The present disclosure promotes distribution of sensor data among a plurality of business operators. A controller that an information processing system according to the present disclosure includes collects first data including a plurality of items and personal information from mobile bodies belonging to a first business operator. The controller converts the first data to second data not being usable to identify individuals. The controller provides data in a range decided based on content of a predetermined data use contract, among the second data, to a second business operator. The controller calculates a consideration for the data that is to be paid by the second business operator, based on a data use record of the second business operator.
