Internet users, if you’re a Google Plus member, you may have inadvertently given permission for your picture to be used in an online ad.  Internet security consultant Keith Squires says this could happen if you’re active on some websites. 

“Anytime you do anything to like products or review products,” says Squires, “their privacy terms have changed so that they can use any of that in their advertisements.”

They’re just maximizing revenue opportunities.

“There is a pretty easy way to opt out,” he says, under your shared endorsement setting, in your Google Plus permissions, you can tell them you don't want them to do that.”

Only Google Plus members are vulnerable because the company has your picture.  He says Facebook does the same thing – and doesn’t offer an opt-out choice.
