Apparatus and method for controlling profile data delivery

A profile data delivery control method to be executed by a computer including a memory and a processor, the profile data delivery control method comprising:

• reading, by the processor, a public key and a private key corresponding to the public key from the memory;
• obtaining, by the processor, with respect to each of two or more services provided using a server, profile data including identification information of said each service, and when the profile data satisfies a prescribed validity condition, attaching a signature to the profile data using the private key;
• and
• embedding, by the processor, the public key in a client application so that the public key is used to verify the signature, and delivering the client application with the public key embedded, the client application causing a client to perform an authentication process based on the profile data.

A non-transitory computer-readable storage medium storing a profile data delivery control program that causes a processor of a computer including a memory and the processor to perform a process including:

• reading a public key and a private key corresponding to the public key from the memory;
• obtaining, with respect to each of two or more services provided using a server, profile data including identification information of said each service, and when the profile data satisfies a prescribed validity condition, attaching a signature to the profile data using the private key;
• and
• embedding the public key in a client application so that the public key is used to verify the signature, and delivering the client application with the public key embedded, the client application causing a client to perform an authentication process based on the profile data.
