At this season every year, I stand in for file a final tax return for my father and mother.

Until now, I tried to do the filing return by digital certificate service of the Basic Resident Register, however this year I noticed that the service had been expired, and have to do a mailing procedure.

Even so, the available period of the digital certificate service is three years, and I am afraid that it is too short.

I think that I had paid for the procedures, for example taking my parents to a municipal office and asking them to to sign autograph

Of course, I know it is difficult to prevent a digital certificate service from being misused, and it cannot be helped. however it is annoying me.

If there is a digital certificate service with zero risk, it might be no problem, however, even if the technology will be prefect, there is no point with rough management.

When I went to the event of final tax return at a city hall, I was very surprised to find a person's private information(ID number, address and password) in a buffer of the official PC.
