         6 . The method of trading artwork according to  claim 5 , comprising:
 transmitting the secret key and third information to the external device, the third information identifying the uploaded artwork which is encrypted and embedded with the QR code.   
     
     
         7 . A computer comprising:
 receiving circuitry, which, in operation, receives an acquisition request, from an external device, to acquire uploaded artwork; and   processing circuitry, which, in response to the acquisition request, issues a transaction to a contract account on a blockchain network, the transaction including first information regarding the acquisition request and second information regarding the uploaded artwork.   
     
     
         8 . The computer according to  claim 7 , wherein the processing circuitry, in operation, embeds a QR code in the uploaded artwork. 
     
     
         9 . The computer according to  claim 8 , wherein the processing circuitry, in operation, uses a data encryption key to encrypt the uploaded artwork, in which the QR code is embedded. 
     
     
         10 . The computer according to  claim 9 , comprising:
 transmitting circuitry, which, in operation, transmits third information to the external device, the third information identifying the uploaded artwork which is encrypted and embedded with the QR code.   
     
     
         11 . The computer according to  claim 9 , wherein the processing circuitry, in operation,
 generates a pair of a public key and a secret key; and   applies the public key to encrypt the data encryption key.   
     
     
         12 . The computer according to  claim 11 , comprising:
 transmitting circuitry, which, in operation, transmits the secret key and third information to the external device, the third information identifying the uploaded artwork which is encrypted and embedded with the QR code.   
     
     
         13 . A non-transitory computer-readable medium including a computer-executable program which, when executed by a computer, causes the computer to perform:
 receiving an acquisition request, from an external device, to acquire uploaded artwork; and   in response to the acquisition request, issuing a transaction to a contract account on a blockchain network, the transaction including first information regarding the acquisition request and second information regarding the uploaded artwork.   
     
     
         14 . The non-transitory computer-readable medium according to  claim 13 , wherein the program, when executed by the computer, causes the computer to perform:
 embedding a QR code in the uploaded artwork.   
     
     
         15 . The non-transitory computer-readable medium according to  claim 14 , wherein the program, when executed by the computer, causes the computer to perform:
 using a data encryption key to encrypt the uploaded artwork, in which the QR code is embedded.   
     
     
         16 . The non-transitory computer-readable medium according to  claim 15 , wherein the program, when executed by the computer, causes the computer to perform:
 transmitting third information to the external device, the third information identifying the uploaded artwork which is encrypted and embedded with the QR code.   
     
     
         17 . The non-transitory computer-readable medium according to  claim 15 , wherein the program, when executed by the computer, causes the computer to perform:
 generating a pair of a public key and a secret key; and   applying the public key to encrypt the data encryption key.   
     
     
         18 . The non-transitory computer-readable medium according to  claim 17 , wherein the program, when executed by the computer, causes the computer to perform:
 transmitting the secret key and third information to the external device, the third information identifying the uploaded artwork which is encrypted and embedded with the QR code.
