Japanese electronics and entertainment giant Sony has claimed that its PlayStation Network (PSN) service has become more secure than ever.

Speaking about the high-profile PSN Hack in April, at the IFA Electronics Show in Berlin, Sony chief executive Howard Stringer said that the summer of discontent has passed.

Sony Corp.’s Chief Executive Howard Stringer on Tuesday described the recent PSN hack as “a hiccup”, and said that no system is cent per cent secure.

In his first public comments on the PSN attack, 69-year-old Stringer said, “This is a hiccup in the road to a network future. Nobody's system is 100 percent secure.”

Still muddling through the aftershocks sophisticated PSN hacking attacks, Sony is now mulling over a plan to announce a reward for information leading to the arrest of the hackers.

According to a report published by AllThingsDigital, the option to offer a reward to catch the hackers is on the table, though the Japanese electronics giant is yet to reach a final decision.

Sony Chief executive Howard Stringer has apologized to the PlayStation Network members over a recent security breach that left more than 100 million customers vulnerable to personal information thefts.

Stringer said that they could not notify customers about the security breach in time because they needed time to determine the extent of the damage.
