"According to Omron, the Okao software pack can also recognize faces and facial attributes to estimate a person’s gender, age and ethnicity."
...and then send that information to third-party companies???
Isn't the whole stink about Amazon is that they keep the customers for themselves? Amazon knows how to profit from data without sending it anywhere, it would seem. They would have little motive in sharing that info with anyone. I can't see how that's a bad thing for privacy.
Ok, but I would still be creeped out by Amazon estimating details about me by using facial recognition techniques. I'm much more comfortable with them knowing about the products I choose to buy because I am aware of the information I am giving to them.
