Abstract

A personal data providing system includes a plurality of first information processing apparatuses. Each of the first information processing apparatuses executes a first process including transmitting an inquiry for an encrypting method of an individual identifier to a terminal of each of individuals, and encrypting each of the individual identifiers into a code based on a response to the inquiry received from the terminal of each of the individuals, and corresponding the code of each of the individuals to personal data of each of the individuals.

First claim

What is claimed is:

1. A personal data providing system comprising:
a plurality of first information processing apparatuses and a second information apparatus,
wherein each of the plurality of the first information processing apparatuses includes:
a first memory, and
a first processor coupled to the first memory and configured to execute a first process, the first process comprising:
transmitting an inquiry for an encrypting method of an individual identifier to a terminal, from among a plurality of terminals associated with a corresponding individual,
encrypting the individual identifier into a code based on a response to the inquiry received from the terminal,
corresponding the code to personal data of the corresponding individual, and
transmitting the code to the second information processing apparatus, wherein
the second information processing apparatus includes:
a second memory, and
a second processor coupled to the second memory and configured to execute a second process, the second process comprising:
specifying a plurality of codes encrypted from a same individual identifier from among a plurality of codes received from the plurality of the first information processing apparatuses,
corresponding a temporary identifier to the plurality of the specified codes, and
transmitting each of the specified codes and the temporary identifier corresponding to the specified codes to the first information processing apparatus designated as a transmission source of the specified codes,
wherein the first process further comprising:
receiving each of the specified codes and the temporary identifier from the second information processing apparatus, and
corresponding the received temporary identifier to the personal data of the individual having the identifier corresponding to the received each of the specified codes.

2. The personal data providing system according to claim 1 , further comprising:
a third information processing apparatus,
wherein the first process further comprising:
transmitting the temporary identifier and the corresponding personal data to the third information processing apparatus, and
the third information processing apparatus includes:
a third memory, and
a third processor coupled to the third memory and configured to execute a third process, the third process comprising:
associating the personal data received from the plurality of the first information processing apparatuses based on the temporary identifier.

3. The personal data providing system according to claim 1 ,
wherein the inquiry is an inquiry for the encrypting method for each type of the personal data.

4. The personal data providing system according to claim 1 ,
wherein the inquiry further includes an inquiry for a password.

5. The personal data providing system according to claim 1 ,
wherein the encrypting method includes a method using a cryptographic hash function.

6. A personal data providing method for a system comprising a plurality of first information processing apparatuses and a second information processing apparatus, the method is executed by the plurality of first information processing apparatuses and the second information processing apparatus, the method comprising:
transmitting, with a first information processing apparatus, an inquiry for an encrypting method of an individual identifier to a terminal, from among a plurality of terminals associate with a corresponding individual,
encrypting, with the first information processing apparatus, the individual identifier into a code based on a response to the inquiry received from the terminal,
corresponding, with the first information processing apparatus, the code to personal data of the corresponding individual, and
transmitting, with the first information processing apparatus, the code to the second information processing apparatus,
specifying, with the second information processing apparatus, a plurality of codes encrypted from a same individual identifier from among a plurality of codes received from the plurality of the first information processing apparatuses,
corresponding, with the second information processing apparatus, a temporary identifier to the plurality of the specified codes, and
transmitting, with the second information processing apparatus, each of the specified codes and the temporary identifier corresponding to the specified codes to the first information processing apparatus designated as a transmission source of the specified codes,
receiving, with the first information processing apparatus, each of the specified codes and the temporary identifier from the second information processing apparatus, and
corresponding, with the first information processing apparatus, the received temporary identifier to the personal data of the individual having the identifier corresponding to the received each of the specified codes.

7. A non-transitory computer-readable medium storing a program for causing a computer to perform a process comprising:
transmitting, with a first information processing apparatus, an inquiry for an encrypting method of an individual identifier to a terminal, from among a plurality of terminals associate with a corresponding individual,
encrypting, with the first information processing apparatus, the individual identifier into a code based on a response to the inquiry received from the terminal,
corresponding, with the first information processing apparatus, the code to personal data of the corresponding individual, and
transmitting, with the first information processing apparatus, the code to a second information processing apparatus,
specifying, with the second information processing apparatus, a plurality of codes encrypted from a same individual identifier from among a plurality of codes received from a plurality of first information processing apparatuses,
corresponding, with the second information processing apparatus, a temporary identifier to the plurality of the specified codes, and
transmitting, with the second information processing apparatus, each of the specified codes and the temporary identifier corresponding to the specified codes to the first information processing apparatus designated as a transmission source of the specified codes,
receiving, with the first information processing apparatus, each of the specified codes and the temporary identifier from the second information processing apparatus, and
corresponding, with the first information processing apparatus, the received temporary identifier to the personal data of the individual having the identifier corresponding to the received each of the specified codes.
