Information processing device, information processing method, and information processing system for canceling device restriction based on similarity between feature-quantity vectors of associated devices

Abstract

There is provided an information processing device, an information processing method, and an information processing system, which are capable of ensuring security and canceling a restriction through a simple procedure, the information processing device including: an acquisition unit that acquires a feature-quantity vector directly or indirectly indicating variations in a time series in at least one of a position and orientation of a housing of each of a plurality of different devices that are previously associated; and a controller that cancels a predetermined restriction set in advance, on the basis of the acquired feature-quantity vector corresponding to each of the plurality of devices.
