description A method includes: allocating a first divided region in a user space to a program executed in a user mode, the first divided region being one of a plurality of divided regions obtained by dividing a storing region of a memory, storing information which indicates that the data to be stored is confidential, in association with the first divided region allocated to the program; storing, when data stored in the first divided region is copied to a second divided region in a kernel space among the plurality of divided regions of the storing region and when the information is associated with the first divided region, the information in association with the second divided region; and dumping, when the second divided region with which the information is associated is included in a dump target, encryption data which is obtained by encrypting the data stored in the second divided region.
