Abstract

To allow for effectively utilizing personal information as needed while keeping the personal information secret.SOLUTION: A system comprises a server for holding and distributing source data obtained by pseudonymizing personal information, and a client terminal having received the source data. A browser of the client terminal having received the source data performs matching processing to add the personal information. The matching processing does not depend on the server and can be performed by JavaScript. Since the personal information is pseudonymized, it has high secrecy and remains safe even if the data is leaked. The processing is performed by the browser, and no special application is required. The system is easy to use because the user does not hold a list of personal information, and the system automatically performs matching even if the user has no knowledge.SELECTED DRAWING: Figure 1

Summary of the Invention

Problems to be Solved by the Invention

[0004] An object of the present invention is to conceal personal information and enable effective utilization of other information.

Means for Solving the Problems

[0005] Provided is a method for using personal information, comprising a server that holds and distributes an original pdf that does not contain personal information, and a client terminal that receives the original data, wherein the client terminal downloads the original data into a browser and downloads the original pdf into the browser, and the browser performs a personal information addition process of adding personal information using a library capable of editing a PDF only with JavaScript.

Effects of the Invention

[0006] Personal information is concealed and can be effectively used as needed.

Brief Description of the Drawings

[0007]

DETAILED DESCRIPTION OF THE INVENTION

[0008] Server 1 holds original data 11a including anonymized personal information and distributes it. Here, anonymization refers to an irreversible concealment method. Since it is anonymized, the risk of being misappropriated is small.

[0009] The browser of the client terminal that has received the distribution performs a matching process using a library that can edit PDFs only with JavaScript, creates usage data 11b including personal information from the original data 11a, and uses the personal information. The matching process can be performed with JavaScript without depending on the server.

EXAMPLE

[0010] Hereinafter, it will be described with reference to the drawings. The server 1 holds PDF original data 11a that does not include personal information, and this is distributed. The browser of the client terminal that has received the distribution adds personal information by a library that can edit PDFs only with JavaScript. The personal information created in this way by the browser can be saved in the client terminal, but such a method of adding personal information is unprecedented.

[0011] The advantages of such a method are: (1) the user does not need to use a special application; (2) the user does not need to perform special operations (preventing human errors); (3) the system can automatically match personal information to a PDF file whose owner is unknown; (4) the user does not need to hold a list of personal information.

INDUSTRIAL APPLICABILITY

[0012] It is a method that can be easily used based on a PDF that does not include personal information. It can be considered for use by many users.
