Abstract

To provide an information processing apparatus, a reading control method, and a computer readable storage medium that can improve the secrecy of information written in a secret area compared with the case of controlling access only by authentication, the information processing apparatus includes a nonvolatile memory that has a secret area where secret information is stored, an authentication controller that authenticates access to the nonvolatile memory, a flag information storage unit that stores flag information, and a memory controller that controls access to the nonvolatile memory by using the flag information stored in the flag information storage unit. The memory controller allows reading of the secret information from the secret area when a value of the flag information is a specified value and validity of access is authenticated by the authentication controller.
