Method and apparatus for managing game data

A method, performed by a game providing apparatus, of managing game data, the method comprising:

• obtaining first event data related to a first event having occurred in a game service, and first state data related to a first state that is a result according to the occurrence of the first event;
• obtaining a first event hash by applying the first event data to a hash function;
• and
• obtaining a first state hash by applying a combination of the first state data and the first event hash to the hash function.

A game providing apparatus comprising:

• a memory storing instructions;
• and
• at least one processor functionally connected to the memory and configured to execute the instructions to:
• obtain first event data related to a first event having occurred in a game service;
• obtain a first event hash by applying the first event data to a hash function;
• obtain second event data related to a second event having occurred in the game service after the first event;
• and
• obtain a second event hash by applying a combination of the second event data and the first event hash to the hash function.

A server comprising:

• a memory storing instructions;
• and
• at least one processor functionally connected to the memory and configured to execute the instructions to:
• obtain first event data related to a first event having occurred in a game service;
• obtain a first event hash by applying the first event data to a hash function;
• obtain second event data related to a second event having occurred in the game service after the first event;
• and
• obtain a second event hash by applying a combination of the second event data and the first event hash to the hash function.

A user terminal for providing a game service, the user terminal comprising:

• a user input unit configured to receive a user input;
• a memory storing instructions;
• and
• at least one processor functionally connected to the user input unit and the memory, and configured to execute the instructions to:
• obtain first event data related to a first event having occurred in the game service;
• obtain a first event hash by applying the first event data to a hash function;
• obtain second event data related to a second event having occurred in the game service after the first event;
• and
• obtain a second event hash by applying a combination of the second event data and the first event hash to the hash function.

A computer-readable recording medium having recorded thereon a program for executing, on a computer, a method of managing game data, the method comprising:

• obtaining first event data related to a first event having occurred in a game service;
• obtaining a first event hash by applying the first event data to a hash function;
• obtaining second event data related to a second event having occurred in the game service after the first event;
• and
• obtaining a second event hash by applying a combination of the second event data and the first event hash to the hash function.
