A Statement Regarding Interview by NHK of Japan About Tor Technology

This is a document originally written on September 20th, regarding interview about Tor conducted by NHK (Japan Broadcasting Corporation)

Written on 9/20/2012

I’ve received inquiries from NHK (Nippon Housou Kyoukai) regarding interview they want to do with me. As they will be having a discussion of anonymizing technology in their show called Science Zero to be aired on October 7th, they wanted to do a segment with me, in the topic of why use Tor.

I maintain information site for GnuPG in Japanese and advocacy of information technology is a big thing for me, thus, I accepted their inquiry to appear on TV.

The interview itself was conducted over Google Hangout, for about an hour. Being myself not used to those press interviews, there were times I have explained things for quite a bit of time. (They wanted something simple.)

And this is what happened so far.

So answering their questions, why use Tor, first point is that it is useful when searching for “questionable” matters. (For instance, I am interested in military technologies, like submarines) I feel it is a real threat as in post-9/11 era, information that used to be public is now obscured. Also, eavesdropping capability of NSA is improving in recent year, it is a real fear my activity online would be interpreted in pieces, causing misunderstandings. Another point is simply that the importance of this type of technology only increases over time. I am not sure how they will be using my interview footage, but I wanted to write few words about it.

I am in a stance that information itself should never be incriminating. It is more of the statement that what matters if what action people take with these information in hand, and it’s not the information itself that is a crime. This is also related to freedom of the speech, but regulating information itself will inevitably infringe such freedom of the speech. This is because globally speaking, the only way to protect your own free speech is to also protect someone else.

It is very challenging to describe question of why use Tor without myself sounding like a conspiracy theorist. In practicality, deep webs, such as Hidden Service and Freenet are also important to cover, but as a scope of this interview, I mainly explained it in context of Tor use in public web. (As deep web is not easily perceived by the general public, it would require its own session to explain about it.)

These technologies are in surge of being more important, and I am looking forward to see how this is covered in the show.

More opinions to come after viewing the show.

NHK just wrote to me that they had to cut my segment due to time constraints. Bummer, but oh well.
