Japan Stalls PlayStation Network Relaunch Over Security Concerns

Over the weekend, Sony began restoring service to the PlayStation Network following an unprecedented data breach that exposed the personal information of 100 million users around the world. Gamers are eager to get back online, but some will have to wait longer than others.

In Japan, doubts about the network's security are so strong that the government has said that PSN service will not return without certain guarantees from Sony.

Kazushige Nobutani, director of the Media and Content Industry department at the Japanese Ministry of Economy, Trade and Industry, spoke with Dow Jones Newswires on Sunday and explained the steps Sony would have to take before earning Japan's trust.

"We met with Sony on May 6 and 13," he said, "and basically we want two things from them. [...] The first is preventative measures. As of May 13, Sony was incomplete in exercising measures that they said they will do on the May 1 press conference. [...] There were similar cases in the past that were caused by other firms, and we are asking Sony whether their measures are good enough when compared to countermeasures taken in the past."

Sony vowed on Saturday in a video release that the company had "greatly enhanced our data security systems." Soon thereafter, Sony entertainment services began rolling out to regions around the world, starting with the Americas, Europe, Australia, New Zealand, and the Middle East.
