Abstract

According to one embodiment, an information management device includes an individual information manager configured to allocate a second identifier to a second individual obtained by performing a first operation on a first individual to which a first identifier is allocated; and a data generator configured to generate first data including the first identifier, the first operation, and the second identifier.

First claim

1 . An information management device comprising:
an individual information manager configured to allocate a second identifier to a second individual obtained by performing a first operation on a first individual to which a first identifier is allocated; and a data generator configured to generate first data including the first identifier, the first operation, and the second identifier.

2 . The information management device according to claim 1 , further comprising a calculator configured to calculate a first value based on the first data, wherein the first value is associated with the first data.

3 . The information management device according to claim 2 , further comprising an information writer configured to write first notification information including the first value and the second identifier to a first medium for the second individual.

4 . The information management device according to claim 3 , wherein the individual information manager transmits the first data to the first information management device when the individual information manager receives a first information acquisition request including the first value from a first information management device.

5 . The information management device according to claim 4 , wherein
the individual information manager sets a flag including permission of disclosure in association with the first data, and the individual information manager transmits the first data when the flag indicates permission.

6 . The information management device according to claim 4 , wherein
the individual information manager sets a flag including non-permission of disclosure in association with the first data, and the individual information manager does not transmit the first data when the flag indicates non-permission.

7 . The information management device according to claim 1 , further comprising an information reader configured to read the first identifier from a second medium for the first individual.

8 . The information management device according to claim 1 , further comprising an information reader configured to read, from a second medium for the first individual, second notification information including a second value and the first identifier, the second value being based on second data, wherein the data generator generates third data, the third data including the second value, the first identifier, the first operation, and the second identifier.

9 . The information management device according to claim 8 , wherein
the first individual is obtained by performing a second operation on a third individual in a second process, and the second data includes a third identifier of the third individual, the second operation, and the first identifier.

10 . The information management device according to claim 8 , further comprising a calculator configured to calculate a third value based on the third data, wherein the third value is associated with the third data.

11 . The information management device according to claim 10 , further comprising an information writer configured to write third notification information including the third value and the second identifier to a first medium for the second individual.

12 . The information management device according to claim 10 , further comprising an individual information acquirer configured to transmit a second information acquisition request including the second value to a second information management device and receive the second data from the second information management device.

13 . The information management device according to claim 12 , wherein
the individual information manager receives, from a first information management device, a third information acquisition request including the third value, when the third information acquisition request is received, the individual information acquirer transmits the second information acquisition request to the second information management device, and the individual information manager transmits the second data and the first data to the first information management device.

14 . The information management device according to claim 13 , wherein
a flag including permission of disclosure is associated with the second data, and the individual information acquirer transmits the third information acquisition request to the second information management device when the flag indicates permission.

15 . The information management device according to claim 13 , wherein
a flag including non-permission of disclosure is associated with the second data, and the individual information acquirer does not transmit the third information acquisition request to the second information management device when the flag indicates non-permission.

16 . The information management device according to claim 12 , wherein the individual information manager specifies a history of operation on the second individual based on the first data and the second data.

17 . The information management device according to claim 16 , wherein the individual information manager determines whether the history of operation on the second individual has inconsistency based on an order of the operation in the second data and the operation in the first data.

18 . The information management device according to claim 16 , wherein the individual information manager determines whether the history of operation on the second individual has inconsistency in accordance with whether the first identifier in the second data matches the first identifier in the first data.

19 . The information management device according to claim 1 , wherein the second identifier includes an identifier that identifies a unit of management of the second individual.

20 . The information management device according to claim 19 , wherein the second identifier further includes at least one of an identifier that identifies the type of the second individual, an identifier that uniquely identifies the second individual, and an identifier of a management system configured to perform management of the second individual.

21 . The information management device according to claim 1 , further comprising a first operation acquirer configured to acquire the first operation performed by the first individual.

22 . The information management device according to claim 1 , wherein the data generator generates, as the first data, data including the first identifier, the type of the first operation, and the second identifier.

23 . The information management device according to claim 22 , further comprising a second operation acquirer configured to acquire the type of the first operation performed by the first individual.

24 . The information management device according to claim 22 , wherein the first operation includes at least one of a create operation to create an individual, a unite operation to unite a plurality of individuals, a divide operation to divide an individual, a convert operation to convert an individual, and a delete operation to delete an individual.

25 . An information management method comprising:
allocating a second identifier to a second individual obtained by performing a first operation on a first individual to which a first identifier is allocated; and generating first data including the first identifier, the first operation, and the second identifier.

26 . A non-transitory computer readable medium having a compute
