The purpose of the present invention is to improve the convenience of managing rights related to content. An information processing system executes control allowing a client to use content linked to the smart contact on a blockchain while an owner retains ownership of the smart contact. A first control unit executes control to encrypt and store the content using a private key and also save a first key. A second control unit executes control to set content usage rights for a client who has satisfied an authorization to pay a rental fee. A third control unit, upon receiving a content usage request from the client, executes control to transmit the encrypted content to a media player to be operated by the client. A fourth control unit executes control to transmit, for example, a sub-key corresponding to the private key to the media player on the condition of confirming that the client has usage rights.
