An information processing device includes: a data processing unit that executes a process of reproducing content recorded in a medium, wherein the data processing unit acquires a token from the medium, the token being management data corresponding to content recorded in the medium, compares a server ID recorded in the acquired token with a server ID recorded in a server certificate acquired from a server from which the management data is acquired, and halts reproduction of content when the two server IDs are not identical.
