Abstract

Claims (63)

1 . An information processing apparatus comprising:

an eUICC (Embedded Universal Integrated Circuit Card) that holds first profile information that is used for connection to a first communication system and that is associated with a first owner of the information processing apparatus;

an applet configured to generate first authentication information with the first profile information as a key; and

a processor configured to connect to the first communication system by using the first profile information, wherein

the processor is further configured to

acquire, from a second server that manages profile information, the first profile information and the applet;

store the first profile information and the applet in the eUICC;

start the applet, and cause the applet to generate the first authentication information:

acquire, from a predetermined certificate authority, a first electronic certificate that certifies that the first authentication information is for the first owner, the first authentication information being used for authentication by a first server trusted by the first communication system and corresponding to the first profile information;

store the first authentication information and the first electronic certificate in the eUICC; and

receive authentication by the first server by using the first authentication information and the first electronic certificate, and

wherein, in a case where the applet is updated, the processor is configured to

acquire, from the second server, at least updated applet;

store the updated applet in the eUICC;

start the updated applet, and cause the updated applet to newly generate the first authentication information;

acquire, from the predetermined certificate authority, the first electronic certificate in relation to the newly generated first authentication information; and

store, in the eUICC, the newly generated first authentication information and the first electronic certificate that is newly acquired.

2 . The information processing apparatus according to claim 1 , wherein

the processor is configured to

acquire, from the predetermined certificate authority, in a case where second profile information that is newly held in the eUICC is enabled, a second electronic certificate that certifies that second authentication information corresponding to the second profile information is for a second owner, the second profile information being used for connection to the first communication system, and being associated with the second owner of the information processing apparatus,

store the second authentication information and the second electronic certificate in the eUICC, and

receive authentication by the first server by using the second authentication information and the second electronic certificate, and

the first profile information and the first electronic certificate are disabled or deleted.

3 . The information processing apparatus according to claim 1 , wherein, after authentication by the first server, the first owner is identified by the first server based on the first electronic certificate, and the processor is configured to receive provision of a service with contents matching the first owner from the first server.

4 . The information processing apparatus according to claim 1 , wherein

the eUICC does not hold the first profile information and holds default profile information that is used for connection to the first communication system, at a time of shipping from a factory, and

the processor is configured to

connect to the first communication system by enabling the default profile information,

disable the default profile information and enable the first profile information, in a case where the first profile information is acquired from the second server that manages profile information and is stored in the eUICC, and

disable or delete the first profile information and enable the default profile information, in a case where a predetermined secondhand dealer sells the information processing apparatus second hand.

5 . The information processing apparatus according to claim 1 , wherein

the information processing apparatus is mounted on a vehicle,

the first communication system is a system that is managed by a manufacturer of the vehicle, and

the first profile information is issued by the first communication system in a case where the vehicle is purchased by the first owner.

6 . A method executed by a computer, the computer including an eUICC (Embedded Universal Integrated Circuit Card) that holds first profile information that is used for connection to a first communication system and that is associated with a first owner of an information processing apparatus, and an applet configured to generate first authentication information with the first profile information as a key, the method comprising:

acquiring, from a second server that manages profile information, the first profile information and the applet;

storing the first profile information and the applet in the eUICC; and

starting the applet, and causing the applet to generate the first authentication information;

connecting to the first communication system by using the first profile information;

acquiring, from a predetermined certificate authority, a first electronic certificate that certifies that first authentication information is for the first owner, the first authentication information being used for authentication by a first server trusted by the first communication system and corresponding to the first profile information;

storing the first authentication information and the first electronic certificate in the eUICC; and

receiving authentication by the first server by using the first authentication information and the first electronic certificate,

wherein, in a case where the applet is updated, the method further comprising:

acquiring, from the second server, at least updated applet;

storing the updated applet in the eUICC;

starting the updated applet, and causing the applet to newly generate the first authentication information;

acquiring, from the predetermined certificate authority, the first electronic certificate in relation to the newly generated first authentication information; and

storing, in the eUICC, the newly generated first authentication information and the first electronic certificate that is newly acquired.

7 . The method according to claim 6 , further comprising

acquiring, from the predetermined certificate authority, in a case where second profile information that is newly held in the eUICC is enabled, a second electronic certificate that certifies that second authentication information corresponding to the second profile information is for a second owner, the second profile information being used for connection to the first communication system, and being associated with the second owner of the information processing apparatus,

storing the second authentication information and the second electronic certificate in the eUICC, and

receiving authentication by the first server by using the second authentication information and the second electronic certificate, wherein

the first profile information and the first electronic certificate are disabled or deleted.

8 . The method according to claim 6 , wherein

the eUICC does not hold the first profile information and holds default profile information that is used for connection to the first communication system, at a time of shipping from a factory, and

further comprising

connecting to the first communication system by enabling the default profile information,

disabling the default profile information and enabling the first profile information, in a case where the first profile information is acquired from the second server that manages profile information and is stored in the eUICC, and

disabling or deleting the first profile information and enabling the default profile information, in a case where a predetermined secondhand dealer sells the information processing apparatus second hand.

9 . The method according to claim 6 , wherein

the computer is mounted on a vehicle,

the first communication system is a system that is managed by a manufacturer of the vehicle, and

the first profile information is issued by the first communication system in a case where the vehicle is purchased by the first owner.
