20% of Japan consumer sites secretly track web users: Nikkei survey

Forget cookies, device fingerprinting offers more subtle way to watch

TOKYO -- While internet users have become used to accepting or denying cookies when they log on to a website, device fingerprinting has developed into the latest hot-button issue over online privacy and has exposed the scant regulation in Japan surrounding keeping people's information private.
