Abstract
There is provided with an information processing apparatus. A memory stores a module, data, and a valid hash value that is a hash value generated for the data. A calculation unit calculates a hash value of the module stored in the memory and a hash value of the data stored in the memory. A determination unit determines whether the hash value of the data calculated by the calculation unit matches the valid hash value. A transmission unit transmits the hash value of the module calculated by the calculation unit and information representing a determination result of the determination unit to a server which verifies integrity of the module and the data stored in the memory.
Claims18
An information processing apparatus comprising:
- a memory configured to store a module, data, and a valid hash value that is a hash value generated for the data;
- a calculation unit configured to calculate a hash value of the module stored in the memory and a hash value of the data stored in the memory;
- a determination unit configured to determine whether the hash value of the data calculated by the calculation unit matches the valid hash value;
- and
- a transmission unit configured to transmit the hash value of the module calculated by the calculation unit and information representing a determination result of the determination unit to a server configured to verify integrity of the module and the data stored in the memory.
