Information management method and information management system
First Claim
1. An information management method executed by an information management apparatus which manages information, the information management apparatus including a non-transitory memory storing a program and a hardware processor that executes the program so as to perform the information management method, the information management method comprising:
- receiving, from a first server via a network, device history information and first anonymized user information, the device history information indicating a history of an operation of a device used by a first user, and the first anonymized user information being generated by anonymizing, according to a predetermined rule, first user information including attribute information which allows identification of the first user and attribute information which does not allow identification of the first user, by deleting and truncating information which allows identification of the first user based on the predetermined rule;
receiving, from a second server, via the network, service history information and second anonymized user information different from the first anonymized user information, the service history information indicating a history of service used by a second user, the second anonymized user information being generated by anonymizing, according to the predetermined rule, second user information including attribute information which allows identification of the second user and attribute information which does not allow identification of the first user, by deleting and truncating information which allows identification of the first user based on the predetermined rule, and the second server being different from the first server;
associating the device history information and the service history information with each other and managing, as composite information, the device history information and the service history information associated with each other, when the first user identified using the first anonymized user information and the second user identified using the second anonymized user information are determined to be similar, based on commonality between attribute information which is not anonymized, does not allow identification of the first user, and is included in the first anonymized user information and attribute information which is not anonymized, does not allow identification of the second user, and is included in the second anonymized user information;
generating proposal information indicating a first proposal of service to the first user and a second proposal of service to the second user, based on the composite information; and
providing the generated proposal information including the first proposal to the first user via the first server and providing the generated proposal information including the second proposal to the second user via the second server.

Abstract
An information management method includes: receiving, from a manufacturer server via a network, device history information indicating a history of an operation of a device used by a first user and first anonymized user information generated by anonymizing, according to a predetermined rule, first user information including attribute information which allows identification of the first user; receiving, from a service provider server different from the manufacturer server via the network, service history information indicating a history of service used by a second user and second anonymized user information generated by anonymizing, according to the predetermined rule, second user information including attribute information which allows identification of the second user; and associating the device history information and the service history information and managing them as composite information, when the first anonymized user information and the second anonymized user information are determined to be identical or similar.

14. An information management system comprising:
-
an information management apparatus which manages information; a first server which stores device history information indicating a history of an operation of a device used by a first user and first user information including attribute information which allows identification of the first user; and a second server which stores service history information indicating a history of service used by a second user and second user information including attribute information which allows identification of the second user, wherein the information management apparatus includes a non-transitory memory storing a program and a hardware processor that executes the program so as to; receive, from a first server via a network, the device history information and first anonymized user information which is generated by anonymizing, according to a predetermined rule, the first user information with attribute information which does not allow identification of the first user, by deleting and truncating information which allows identification of the first user based on the predetermined rule; receive, from a second server via the network, the service history information and second anonymized user information different from the first anonymized user information which is generated by anonymizing, according to the predetermined rule, the second user information with attribute information which does not allow identification of the first user, by deleting and truncating information which allows identification of the first user based on the predetermined rule; when the information management apparatus determines that the first user identified using the first anonymized user information and the second user identified using the second anonymized user information are similar, based on commonality between attribute information which is not anonymized, does not allow identification of the first user, and is included in the first anonymized user information and attribute information which is not anonymized, does not allow identification of the second user, and is included in the second anonymized user information, the information management apparatus associates the device history information and the service history information with each other and manages, as composite information, the device history information and the service history information associated with each other, generate proposal information indicating a first proposal of service to the first user and a second proposal of service to the second user, based on the composite information, and provide the generated proposal information including the first proposal to the first user via the first server and provide the generated proposal information including the second proposal to the second user via the second server. - View Dependent Claims (15)
