An Ontario woman who is fronting a class action lawsuit against Sony Corp. says she remains a fan of the tech giant's products, but thinks customers should be compensated after hackers breached its security and stole the personal information of more than 100 million users.

Natasha Maksimovic, of Mississauga, Ont., says more than one million Canadians were among those who had trusted Sony with their personal information in exchange for access to its PlayStation and Qriocity online networks.

"My personal information is on the PlayStation Network, as well as Qriocity, so my concern is that my information could get into unauthorized hands. As well my friends and family may have been adversely affected," Maksimovic told CTV News Channel on Wednesday.

Sony Corp. announced on Monday that computer hackers had breached their security system and may have stolen personal information from more than 100 million accounts, including names, addresses, passwords and billing information.

McPhadden Samac Tuovi, a Toronto law firm, has proposed a class action lawsuit against Sony Japan, Sony USA and Sony Canada for breach of privacy.

The lawsuit claims damages in excess of $1 billion, including the cost of credit monitoring services and fraud insurance for those affected for two years.

Maksimovic, 21, the representative plaintiff in the action, says people should be able to trust huge multinational corporations like Sony to protect their private information.

Maksimovic calls herself a "loyal customer" to Sony and says she uses a number of their products, including the PlayStation Portable Go and a Sony book reader.

To use the Sony reader, Maksimovic signed up to their Qriocity network, and became a member of the PlayStation Network to use her portable gaming device.

"They are concerned and they are worried too. Their system was hacked, it is a big issue for them as well," Maksimovic conceded.

Sony has up to 20 days to file a statement of defence in Canada and up to 40 days to do son in the United States.
