An information processing device includes: an acquisition unit that acquires, for a plurality of evaluators, evaluation data indicating evaluation of an evaluation target generated by the evaluator and a value indicating worth of the evaluator; a conversion unit that converts the evaluation data into absolute evaluation data on the basis of the evaluation data and the value indicating the worth of the plurality of evaluators; and a controller that performs control to record the absolute evaluation data in a distributed ledger. The present technology can be applied to a blockchain network.

Abstract: A sensor system includes a sensing element, an illumination optical system including a light source, the illumination optical system being configured to obliquely illuminate the sensing element, and a detector device configured to detect light reflected off the sensing element. The sensing element includes a chemical sensing layer configured to change in an optical characteristic in response to contact with a target substance, a reflection layer configured to reflect at least part of incident light, and an intermediate layer located between the reflection layer and the chemical sensing layer. The detector device is configured to separately detect p-polarized light and s-polarized light reflected off the sensing element.

Abstract: An optical detection type chemical sensor includes a light source, a detection element and a photodetector. The detection element is constituted of a laminate in which a multilayer film including a chemical detection layer, an optical interference layer, and a half mirror layer is formed on a transparent substrate. At least one of the layers includes a magnetic material. Light from the light source is applied to the detection element under the condition that the light enters inside of the detection element from the rear surface of the transparent substrate on which the laminate is not formed and multiple reflection occurring in the laminate intensifies the magneto-optical effect. A subject is detected by using the photodetector to detect a magneto-optical signal indicating a change in reflected light from the laminate resulting from a change in an optical property resulting from a reaction in the chemical detection layer.
