APPLICATION DISTRIBUTION SYSTEM, APPLICATION DISTRIBUTION METHOD, TERMINAL, AND PROGRAM

摘要

Certificate data contained in an execution file have been stored as a certificate file in protected data storage area 14 that has been access-restricted. Thereafter, when an execution file that does not contain certificate data is distributed as an update execution tile from application distribution server 40, the update execution file is executed based on the certificate file stored in protection data storage area 14 so as to use the application.
