The top story in the May 26th Nikkei Shimbun is "Japan Post to use 7-digit alphanumeric address identification; Rakuten Group and others considering implementation for delivery," but experts are already raising concerns. Professor Ichiro Sato of the National Institute of Informatics and Naoki Asakawa, editorial writer for Nikkei BP, are among those who commented on NIKKEI THINK. Their points are all valid. Of course, there are also various advantages... The issue of digitizing postal addresses is something I've been thinking about for a while...

What "number" design should be - In response to the pension number leak incident

In the pension number leak incident, it seems they're going to change "all the leaked numbers." Personally, I'm feeling a bit disappointed. As I wrote in yesterday's article, if the system is properly managed, the leak of the numbers themselves isn't a big risk, and since the addresses, names, and other information that were leaked along with them can't be changed, changing only the pension numbers doesn't make much sense. On the contrary, if they're going to change older pension number systems, they'll have to change everything else in conjunction with them...

Is it dangerous if the number is leaked?

Well, as we enter the peak of the My Number system boom this summer, how are you all doing? Coincidentally, there's been a massive leak of pension numbers, and there are concerns about its impact on the My Number system. However, I find it strange that the leak of a "number" is causing such a fuss, more so than leaks of other personal information like "address, name, and date of birth." That's because, when it comes to leaks, the privacy impact is…

My Number and Privacy: Identifiers and Excess Risk

In the previous article, "My Number and Privacy: Requirements for Identifiers," I wrote the following. Next, let's consider a hypothetical example: a common number for tax and social security (including pensions). This would need to satisfy the requirements of both a basic pension number and a taxpayer number. In other words, it would require a combination of the "long period" required by pension management and the "broad range" required by taxation. That is, "stable over a long period and broad range"…

My Number and Privacy: Requirements for Identifiers

Recently, it seems that My Number is being covered more frequently in various media outlets [1]. Setting aside the question of whether it's too late, it's better than not being covered at all. Ideally, I should point out any issues with each article, but unfortunately, I'm extremely busy and don't have the time. Therefore, for those discussing these matters, I'll just mention some general points…

Regarding storage and linking of the common number/My Number

First, let's look at the following diagram from the Cabinet Secretariat regarding My Number. The "number" represents the My Number. In this diagram, the My Number ("number") is stored in multiple locations: Information Holding Agency A, Information Holding Agency B, and so on. This is quite strange. Because this almost negates the purpose of using the information sharing platform. Should the My Number be stored as a "code" or...

A heartless society and the number system: The dangers of name matching as seen in Victor Hugo's Les Misérables (2)

Last time, we discussed how combining the internet with a widely used numbering system (generic identifier) ​​could lead to a situation where "everyone is Inspector Javert," potentially resulting in a "heartless society." This time, in addition to that, we will explain the threat posed by combining another internet characteristic, "fragmented information," with "generic identifiers," again using "Les Misérables." (This section was first published in...)

A heartless society and the number system: The dangers of name matching as seen in Victor Hugo's "Les Misérables"

Humans are forgetful creatures. This leads to forgiveness. People act on this premise. But the Internet does not forget. People who do not forget, like Inspector Javert in "Les Misérables," are called heartless, and the damage they cause is called heartless. The careless introduction and use of identifiers, such as "universal immutable numbers," on the Internet will turn anyone on the Internet into a Javert. And what emerges is a "heartless society."
