System, non-transitory computer-readable storage medium, method, and information processing apparatus for executing a communication game with another apparatus

A non-transitory computer-readable storage medium having an executable program for execution of a communication game with communication with another apparatus stored thereon, the program causing a computer comprising content data that is available at least in the communication game when at least a predetermined condition is satisfied and a decryption key to provide execution comprising:

• receiving encrypted data encrypted with an encryption key corresponding to the decryption key from an apparatus among other apparatuses that satisfies the predetermined condition, wherein each of the apparatuses includes the content data that is available at least in the communication game when at least the predetermined condition is satisfied, and the decryption key;
• verifying the received encrypted data based on the decryption key;
• and
• temporarily permitting use of the content data in the communication game when the another apparatus receives a plurality of pieces of the encrypted data and verification of one piece of encrypted data of the plurality of pieces of encrypted data is successful, wherein
• the apparatus and the another apparatus execute the communication game using the content data,
• at least the computer transmits information indicating that the computer satisfies the predetermined condition to at least all other apparatuses included in the other apparatuses, and
• the another apparatus determines whether the another apparatus has received the encrypted data from at least the computer, based on the information indicating satisfaction of the predetermined condition.

A method of executing a communication game with communication between/among a plurality of terminals, each of the plurality of terminals comprising content data that is available at least in the communication game in association with at least a predetermined condition being satisfied and a decryption key, the method comprising:

• transmitting, by a first terminal of the plurality of terminals that satisfies the predetermined condition, encrypted data encrypted with an encryption key corresponding to the decryption key to another terminal when the first terminal executes the communication game;
• verifying, by the another terminal, in association with the another terminal receiving the encrypted data from the first terminal, the encrypted data based on the decryption key;
• and
• temporarily permitting, by the another terminal of the plurality of terminals that does not satisfy the predetermined condition, use of the content data in the communication game by the another terminal in association with the another terminal receiving a plurality of pieces of the encrypted data and verification of one piece of encrypted data of the plurality of pieces of encrypted data being successful, wherein
• the first terminal and the another terminal execute the communication game using the content data,
• at least the first terminal transmits information indicating that the first terminal satisfies the predetermined condition to at least all other terminals included in the plurality of terminals, and
• the another terminal determines whether the another terminal has received the encrypted data from at least the first terminal, based on the information indicating satisfaction of the predetermined condition.

An information processing apparatus configured to execute a communication game with communication with another information processing apparatus, the information processing apparatus comprising:

• processing circuitry including one or more processors;
• content data that is available at least in the communication game when at least a predetermined condition is satisfied;
• and
• a decryption key, wherein
• the processing circuitry is configured to:
• verify, when the one or more processors receive encrypted data encrypted with an encryption key corresponding to the decryption key from an information processing apparatus among other information processing apparatuses that satisfies the predetermined condition, the encrypted data based on the decryption key, and
• permit temporary use of the content data in the communication game when the another information processing apparatus receives a plurality of pieces of the encrypted data and verification of one piece of encrypted data of the plurality of pieces of encrypted data is successful, wherein
• the information processing apparatus and the another information processing apparatus execute the communication game using the content data,
• at least the information processing apparatus transmits information indicating that the information processing apparatus satisfies the predetermined condition to at least all other information processing apparatuses included in the other information processing apparatuses, and
• the another information processing apparatus determines whether the another information processing apparatus has received the encrypted data from at least the first terminal, based on the information indicating satisfaction of the predetermined condition.
