Shares of Sony surged as it returns with some services on its PlayStation Network (PSN). This after the company offered incentives to at least 78 million users whose online personal information is at risk.

With the close of Tokyo markets on Friday, Sony shares increased by 2 per cent at 2,306 yen in an early Monday trade after dropping by 4.5 percent on Thursday.

Several days after the company discovered a network problem PSN users worldwide were exasperated one of the possible first and largest Internet security theft.

Existing users were offered selected free content which included 30 days of free membership to a premium service and pay credit card-renewal fees in some regions. Added payment would only be given if clients experienced damage.

PlayStation’s official fan page on Facebook received thousands of comments from users who conveyed their intention to switch to Microsoft's Xbox Live games network.

Authorities in North America and Europe were prodded to take legal actions and investigations regarding the issue. North America and Europe hold almost 90 percent of the users of the network which allows gamers to download chosen software and compete with other members online.

Sony is the latest Japanese company targeted by criticisms on how it has disclosed to its users the network problem. It can be recalled that
Tokyo Electric Power Co was reviled too on its performance during the nuclear crisis after the March 11 earthquake. In 2010, Toyota Motor Corp was insulted for being unopened about problems over a massive vehicle withdrawal.
