An information processing apparatus that processes data to be protected is provided. The information processing apparatus includes a first storage unit, a second storage unit, and a cache control unit configured to cache data stored in the first storage unit into the second storage unit. The cache control unit is configured to lock a cache region in the second storage unit to thereby prevent cache data of the stored data from being written back into the first storage unit, the cache data being obtainable from the cache region in the second storage unit in which the stored data is cached, and write the data to be protected different from the stored data into the cache region in the second storage unit, after the cache region in the second storage unit is locked.
