Abstract
In a case where a non-volatile memory comes close to the end of a life time and has become ReadOnly, it is impossible to erase data stored in the non-volatile memory, which may lead to a decreased robustness of maintaining confidentiality. A data processing apparatus determines whether the life time of a non-volatile memory is about to expire. In a case where the determination result indicates that the life time of the non-volatile memory is about to expire, the data stored in the non-volatile memory is erased.
