If this new Secret Mode "never leaves a trail of your browsing data", then why do you need to give it your finger print to use it? The point of Secret Mode, Chrome/Chromium's Incognito mode, Internet Explorer's InPrivate mode, Firefox's Private mode, etc. is to give users a limited amount of anonymity. Personally identifying yourself is literally the exact opposite of anonymity. So, when users have to give their fingerprints to use this new mode, I can't help but assume Samsung is sharing that data with others. I'll bet we'll see new stories about how Samsung devices are sending fingerprints, without encryption, across the internet to Samsung. I wonder how much Big Brother is paying Samsung for these finger prints.
