Abstract: An identification device including a generation unit and an information identification unit. The generation unit generates factor information relating to pulse-wave information with respect to an identification target in accordance with biological model information representing a relevance between pulse-wave information representing a pulse wave and the factor information representing a factor of pulse wave. The information identification unit selects certain list information satisfying a predetermined determination criterion of the factor information generated by the generation unit out of list information associating the factor information generated based on the pulse-wave information representing a pulse wave of a biological subject to be an identification target with identification information for identifying the biological subject, and identifies the identification information in the selected certain list information.

Abstract: Provided is an information processing device, etc., that provides information which is the basis for quick detection of abnormalities that occur in a device. An information processing device calculates a degree of suitability between observation information and prediction information, the observation information observed for a system suffering an effect from an certain device, the prediction information predicted in accordance with a model for a state of the system; and calculates a difference between manipulation amount to the certain device and predictive manipulation amount predicted for the manipulation amount based on the model, the difference being a difference in case that the degree satisfies a predetermined calculation condition.
