Sony had to shut down it’s PlayStation Network after the network was hacked earlier this month. Now the company has come out and said that customer data may have been stolen.

Businessweek has more: “Sony Corp. warned its 77 million PlayStation Network and Qriocity online service customers that their credit-card data, billing addresses and other personal information may have been stolen by a hacker.”

While this is not likely to affect the Sony eBook business, the hack raises questions about the security of personal data being stored in the databases of companies that we frequent. Sony, Amazon and Apple all store our credit card numbers making it very easy to buy eBooks at the touch of a button. If a database as large as Sony’s can get hacked –to put the size in perspective, the PlayStation Network has about three times as many users as Netflix– should we be storing all of this data in our digital accounts? What do you think?
