Claims

A personal information data processing method for causing a computer to execute processing for storing or reading personal information data including identification information capable of identifying a specific individual in a storage means,
A default information acquisition step of acquiring default information that defines a predetermined division rule;
A dividing step of dividing the identification information into a first fragment and a second fragment, which cannot identify a specific individual alone, according to the default information;
Generating concatenated key information indicating a correspondence relationship between the first fragment and the second fragment;
Storing the first fragment and the second fragment in different files;
Storing the concatenated key information and the first and second fragments in different storage areas;
A personal information data processing method comprising:

The personal information data processing method according to claim 1, wherein in the default information acquisition step, a space, hyphen, or number of characters between the last name and the name is acquired as default information.

The personal information data processing method according to claim 1, wherein in the default information acquisition step, a name database is searched to acquire a division part of the last name and the name as default information.

Restoring the original identification information from the concatenated key information stored in the storage medium area, the first fragment, and the second fragment;
The personal information data processing method according to claim 1, further comprising:

A personal information data processing method for causing a computer to execute processing for storing or reading out personal information data including identification information that can identify a specific individual in a storage means, and obtaining default information that defines a predetermined division rule A default information acquisition step, a division step of dividing the identification information into a first fragment and a second fragment that cannot identify a specific individual by themselves, according to the default information, and the first fragment and the second fragment Generating concatenated key information indicating a correspondence relationship with a fragment; storing the first fragment and the second fragment in different files; and the concatenated key information and the first and second fragments. A program for causing a computer to execute the step of storing in different storage areas.
