Provided is an information processing device equipped with a processor that selectively performs processing using information acquired from an application. The processor generates second key information on the basis of first key information in a case where the first key information is acquired from an application; retains specific information in a case where the first key information is acquired; determines, on the basis of the specific information, whether an application is a target application, in a case where there is an access by the application after the specific information has been retained; performs processing on the basis of information acquired from the accessing application and the second key information in a case where the application is determined to be a target application; and does not perform processing using information acquired from the accessing application in a case where the application is not determined to be a target application.
