Information processing device and information processing method

An information processing method, comprising:

• obtaining developer identification information and access control information from a user terminal, for controlling execution of at least one function of an information processing device, wherein the developer identification information and the access control information are associated with an application program executed by the user terminal;
• generating first key information;
• outputting the generated first key information to the user terminal;
• obtaining, from the user terminal, first encoded information that is generated by encoding second encoded information based on the first key information;
• encoding the second encoded information based on the first key information to generate third encoded information,
• wherein the second encoded information is generated by encoding of the developer identification information and the access control information based on second key information different from the first key information;
• and
• determining a developer of the application program indicated by the developer identification information as the developer who made an advance request for authorization for use based on
• a match of the generated third encoded information and the obtained first encoded information, and
• a match of the second encoded information and the obtained first encoded information;
• and
• controlling execution of at least a portion of the at least one function based on the access control information and the determination.

A non-transitory computer-readable medium having stored thereon, computer-executable instructions that, when executed by a processor, cause a computer to execute operations, the operations comprising:

• obtaining developer identification information and access control information from a user terminal, for controlling execution of at least one function of an information processing device, wherein the developer identification information and the access control information are associated with an application program executed by the user terminal;
• generating first key information;
• outputting the generated first key information to the user terminal;
• obtaining, from the user terminal, first encoded information that is generated by encoding second encoded information based on the first key information;
• encoding the second encoded information based on the first key information to generate third encoded information,
• wherein the second encoded information is generated by encoding of the developer identification information and the access control information based on second key information different from the first key information;
• and
• determining a developer of the application program indicated by the developer identification information as the developer who made an advance request for authorization for use based on
• a match of the generated third encoded information and the obtained first encoded information, and
• a match of the second encoded information and the obtained first encoded information;
• and
• controlling execution of at least a portion of the at least one function based on the access control information and the determination.
