According to a story in the Daily Beast, Samsung's Smart TV can record conversations when the voice control feature is activated and can then share those conversations with 'third parties'
It's all to do with how the system delivers the content requested by the viewer. If you 'ask' the Smart TV for a particular programme, the device passes that request via the internet to a server, which searches for the requested content and delivers it.
Not surprisingly, Samsung says the data isn't retained or sold on. But it would, wouldn't it?
So if you have the voice recognition feature activated and are making a transaction on your phone, the TV would be able to capture your card details and broadcast them.
It seems like another of those 'good ideas' which companies have, but which aren't thought through.
A while back, gestures were being proposed as the next way to control your TV. Now, it seems, we have to talk to them. What is wrong, you wonder, with using a good old remote?
