Abstract
Provided is a technique to prevent an attribute inference attack against a federated learning model. An information processing apparatus () includes: a detection section () that detects, as an outlier, an output value which falls outside a normal range in terms of magnitude of a value among output values of a decision tree which is undergoing federated learning; and a determination section () that determines, in a case where the outlier has been detected, that the decision tree has vulnerability to an attack to infer an attribute value included in training data which has been used to train the decision tree.
