Classification: CPC H  G | IPC G  H

Claim 0:
1. An information processing method to be performed by an information processing system, the information processing system including
a communication apparatus including a memory storing instructions and at least one processor that executes the stored instructions and configures the communication apparatus to operate as a first communication unit that performs communication via a predetermined wireless communication, and
an information processing apparatus including a memory storing instructions and at least one processor that executes the stored instructions and configures the communication apparatus to operate as a second communication unit that performs communication via the predetermined wireless communication, the information processing method comprising:
writing, in response to a first user operation, by the communication apparatus, key information used to generate a decryption key and first information having a predefined structure that is encrypted by using an encryption key corresponding with the generated decryption key, into a storage area of the communication apparatus that is accessible by the information processing apparatus, the key information and the first information stored in the storage area being readable by the second communication unit of the information processing apparatus;
reading, in response to receipt of a second user operation, by the second communication unit of the information processing apparatus, the key information and the first information that have been written into the storage area of the communication apparatus;
decrypting the first information by using the generated decryption key;
determining whether the decrypted first information corresponds with predetermined second information stored in the information processing apparatus; and
performing, by the information processing apparatus, a registration process for registering the communication apparatus with an application executing on the information processing apparatus when it is determined by the information processing apparatus that the decryption key is generated from the key information, that the first information is decrypted by using the generated decryption key, and the decrypted first information corresponds with the predetermined second information, and not performing, by the information processing apparatus, the registration process when it is determined by the information processing apparatus that the decrypted first information does not correspond with the predetermined second information,
wherein the predetermined second information has been stored in advance of the registration process and without communicating with the communication apparatus.
