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.

Abstract: Disclosed are an analytical element for determining a specific component A in a test sample, based on the specific reaction between said specific component A and a substance B capable of binding specifically to said specific component A, by the use of a labelled material L comprising a label capable of providing a signal and said specific component A or comprising a label capable of providing a signal and a substance C capable of binding specifically to said specific component A, characterized in that said element has a porous reaction layer formed by the use of a mixture containing (a) a carrier having said substance B immobilized thereon and (b) a carrier having an absorbing substance D capable of binding specifically to said labelled material L which has not bound to said substance B or to said specific compound A, to thereby modulate said signal, and an analytical method employing the same.
