Abstract: An information processing system includes an image capturing device and a display device, wherein the image capturing device includes a biometric information acquisition part that acquires biometric information, an authenticating part that authenticates whether or not the biometric information matches registered biometric information registered in advance, an image capturing part that permits capturing of an image on a condition that authentication by the authenticating part is successful, an encryptor that encrypts image data captured by the image capturing part to generate encrypted data, and a data output part that outputs the encrypted data to the display device via a connecting terminal connected to the display device. The display device includes an acquisition part that acquires the encrypted data via a terminal connected to the image capturing device, a decryptor that decrypts the encrypted data, and a display that displays the image data decrypted and acquired by the decryptor.

Abstract: An acquisition part acquires a per-unit license fee for use of the content from the blockchain and a public key issued by an execution management system used by the licensee, from a blockchain in which a contract function is implemented to realize a license agreement. The acquisition part acquires information including a number of pieces of content used by the licensee from the execution management system used by the licensee. A verification part verifies validity of a signature of content usage information. A calculation part calculates a royalty token corresponding to an amount obtained by multiplying the number of pieces of content used by the per-unit license fee, on condition that the signature is valid. A registration part registers the number of pieces of content used and the royalty token in the blockchain.

Abstract: An acquisition part acquires a blockchain in which a plurality of blocks are linked, the blocks store (i) creator information for identifying a creator of a work, (ii) rule information for establishing transaction rules of the work, (iii) information relating to a virtual currency used for a transaction of the work, and (iv) a transfer history of the work and information relating to an exploitation right which is a right established for the work and allows others to use the work. A license information specification part specifies a grantor and a license fee of the exploitation right. A received amount transfer part subtracts a creator's receiving amount from a balance of the virtual currency associated with the grantor, and adds the creator's receiving amount to a balance of the virtual currency associated with a person or management organization designated by the creator of the work.
