Abstract

Provided are an information processing device, an information processing method, and an information processing system that can recognize falling of a communication device. A storage location for storing service information that is information required when a mobile terminal receives a service to be provided via a network is determined based on a security level of the service information and a type of a storage mechanism for storing the service information, included in the mobile terminal.

First claim

The invention claimed is:

1 . An information processing device, comprising:
a determination unit configured to determine a storage location for storage of service information, wherein
the service information is required by a mobile terminal to receive a service via a network,
the determination of the storage location is based on
a security level of the service information, and
a type of a storage mechanism to store the service information included in the mobile terminal,

the service information is assigned to the mobile terminal,
the service information includes an identifier,
the identifier corresponds to a node code which specifies content corresponding to a processing operation of the service information, and
the processing operation of the service information includes at least one of a random service, a cyclic service, or a parsing service.

2 . The information processing device according to claim 1 , wherein the determination unit is further configured to select, based on the security level of the service information, the type of the storage mechanism to store the service information included in the mobile terminal.

3 . The information processing device according to claim 1 , wherein the determination unit is further configured to recognize the type of the storage mechanism, based on capability information of the mobile terminal.

4 . The information processing device according to claim 3 , wherein
the capability information of the mobile terminal indicates presence or absence of a plurality of storage mechanisms, wherein
the plurality of storage mechanisms includes the storage mechanism, and
the type of the storage mechanism includes
a secure element (SE) of the mobile terminal,
a trusted execution environment (TEE) of the mobile terminal, and
a terminal application that is an application program to receive the service in the mobile terminal.

5 . The information processing device according to claim 4 , wherein the determination unit is further configured to determine the security level of the service information based on a condition that the service information is for a service with key or for a service without key.

6 . The information processing device according to claim 5 , wherein in a case where the service information is for the service with key and the mobile terminal includes the SE, the determination unit is further configured to determine the SE as the storage location for the service information.

7 . The information processing device according to claim 5 , wherein in a case where the service information is for the service with key, the mobile terminal excludes the SE, and the service information is prohibited for storage in the type of the storage mechanism which is different from the SE, the determination unit is further configured to determine the determination unit as the storage location for the service information.

8 . The information processing device according to claim 5 , wherein in a case where the service information is for the service with key, the mobile terminal excludes the SE, and the service information is permitted to be stored in the type of the storage mechanism which is different from the SE, the determination unit is further configured to determine the TEE as the storage location for the service information.

9 . The information processing device according to claim 5 , wherein in a case where the service information is for the service with key, the mobile terminal excludes the SE, and the service information is stored in the type of the storage mechanism which is different from the SE, the determination unit is further configured to determine the terminal application as the storage location for the service information.

10 . The information processing device according to claim 5 , wherein in a case where the service information is for the service with key, the mobile terminal excludes the SE, and the service information is stored in the type of the storage mechanism which is different from the SE, the determination unit is further configured to:
convert the service information into a token; and store the token in the determined storage location.

11 . The information processing device according to claim 5 , wherein in a case where the service information is for the service with key and the capability information is unacquired by the information processing device, the determination unit is further configured to:
make an inquiry to a user of the mobile terminal about the storage location for the service information; and determine the storage location based on a response to the inquiry.

12 . The information processing device according to claim 5 , wherein in a case where the service information is for the service with key and the capability information is unacquired by the information processing device, the determination unit is further configured to make a first inquiry to the mobile terminal about the capability information, and
in a case where a response to the first inquiry indicates that the capability information is unacquired by the information processing device, the determination unit is further configured to:
make a second inquiry to a user of the mobile terminal about the storage location for the service information; and
determine the storage location based on a response to the second inquiry.

13 . The information processing device according to claim 5 , wherein in a case where the service information is for the service without key and the service information excludes special identification information, the determination unit is further configured to determine the terminal application as the storage location for the service information.

14 . The information processing device according to claim 5 , wherein in a case where the service information is for the service without key and the service information includes special identification information, the determination unit is further configured to determine the TEE as the storage location for the service information.

15 . The information processing device according to claim 5 , wherein in a case where the service information is for the service without key and the service information includes special identification information, the determination unit is further configured to determine the terminal application, as the storage location for the service information.

16 . The information processing device according to claim 5 , wherein in a case where the service information is for the service without key and the service information includes special identification information, and the capability information is not confirmed by the information processing device, the determination unit is further configured to:
make an inquiry to a user of the mobile terminal about the storage location for the service information, and determine the storage location based on a response to the inquiry.

17 . An information processing method, comprising:
determining a storage location for storing service information, wherein
the service information is required by a mobile terminal to receive a service via a network,
the determination of the storage location is based on
a security level of the service information, and
a type of a storage mechanism for storing the service information included in the mobile terminal,

the service information is assigned to the mobile terminal,
the service information includes an identifier,
the identifier corresponds to a node code which specifies content corresponding to processing operation of the service informa
