Abstract
A program executing apparatus includes a first storage section which stores data permitted to be leaked out; a second storage section which stores secret data of a user; a communication section which can communicate with an external unit; a program storage section which stores at least one application program; and a program executing section, checks a possibility that the secret data could be leaked out to the external unit, and stops the execution of the at least one application program when it is determined that the secret data could be leaked out. The check of the possibility that the secret data could be leaked out is based on whether the at least one application program contains a process of communicating with the external unit or a process of writing data in the first storage section and a process of reading the secret data from the second storage section.
