Hi, I've just discovered this interesting offering from DOCOMO:The only caveat, compared to Thawte's WoT which came way of Dodo:
It does not verify persona.
So, what it's good for, and what - not?
It's still attractive for those who want to play without pay. I believe this case covers 90% or more, however sad that may sound.
It's also good for personal authentication as long as you know that:
(1) e-mail address belongs to an identified person (say, your friend whose e-mail you can positively identify from your previous transactions)
AND
(2) that it's really your friend who's gotten that free DOCOMO offer first.
Because even though your friend still may have access to his e-mail box, so may the bad guy have. And it's not hard for that bad guy to jump first and get that certificate, and peruse it for his deceptive purposes.
There is no persona verification, nobody goes to WoT notary with his passport and another photo Id, so whoever gets that certificate, and has access to the e-mail box (with no SSL used and abundance of free open WiFi it's not hard to do) - can positively forge his identity and make you believe that you are communicating over encrypted channel to your trusted partner.
In other words, "better than nothing", but "nothing for some".
Try it, use it, message me...
