Japanese government accidentally shares internal mails over Google Groups

A government official used the default settings for the service, leaving internal mail exchanges open to public access

A Japanese ministry is conducting an internal investigation after a Google Groups account used for international treaty negotiations was left on its default, publicly viewable settings.

An official at Japan's Ministry of the Environment created the group to share mails and documents related to Japan's negotiations during the Minamata Convention, a meeting held in Geneva in January to create international standards to limit international mercury use. But the official used the default privacy setting, leaving the exchanges open to searches and views in the months since. The information has now been removed.

"The majority of the information that was accessible was not secret, but we're conducting an investigation into the details now," said Michihiru Oi, a ministry official.

Oi said the ministry has its own system for creating groups and sharing documents, but it doesn't always function well outside of Japan, sometimes leading to "poor connections" and a "bad working environment."

Earlier this week the Yomiuri Shimbun, which has the highest circulation of Japan's newspapers, said that over 6,000 items, including private contact information of officials, was publically accessible. The newspaper conducted a broader investigation and said Japanese high schools, health organizations and even political parties had left private details open to the public on Google Groups.

After the news broke, Japanese Minister of the Environment Nobuteru Ishihara hastily ordered a new data security group for the ministry to be formed to investigate the matter. The group held its first meeting on Wednesday.

The framework for the mercury treaty was agreed to in January, with the final version to be signed in Japan in October. It is named "Minamata" after the seaside city in southern Japan where thousands of residents were poisoned by mercury discharges from a local factory in the 20th century.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
