Not in front of the telly: Warning over 'listening' TV
Samsung said personal information could be scooped up by the Smart TV
Samsung is warning customers about discussing personal information in front of their smart television set.
The warning applies to TV viewers who control their Samsung Smart TV using its voice activation feature.
When the feature is active, such TV sets "listen" to what is said and may share what they hear with Samsung or third parties, it said.
Privacy campaigners said the technology smacked of the telescreens, in George Orwell's 1984, which spied on citizens.
Smart TV owner Peter Kent: "It makes me think twice"
The policy explains that the TV set will be listening to people in the same room to try to spot when commands or queries are issued via the remote. It goes on to say: "If your spoken words include personal or other sensitive information, that information will be among the data captured and transmitted to a third party."
Corynne McSherry, an intellectual property lawyer for the Electronic Frontier Foundation (EFF) which campaigns on digital rights issues, told the Daily Beast that the third party was probably the company providing speech-to-text conversion for Samsung.
She added: "If I were the customer, I might like to know who that third party was, and I'd definitely like to know whether my words were being transmitted in a secure form."
Soon after, an activist for the EFF circulated the policy statement on Twitter comparing it to George Orwell's description of the telescreens in his novel 1984 that listen to what people say in their homes.
Privacy experts wondered if the grabbed audio was protected as it was sent for analysis
In response to the widespread sharing of its policy statement, Samsung has issued a statement to clarify how voice activation works. It emphasised that the voice recognition feature is activated using the TV's remote control.
Samsung said: "If a consumer consents and uses the voice recognition feature, voice data is provided to a third party during a requested voice command search. At that time, the voice data is sent to a server, which searches for the requested content then returns the desired content to the TV."
It added that it did not retain voice data or sell the audio being captured. Smart-TV owners would always know if voice activation was turned on because a microphone icon would be visible on the screen, it said.
The third party handling the translation from speech to text is a firm called Nuance, which specialises in voice recognition, Samsung has confirmed to the BBC.
Samsung is not the first maker of a smart, net-connected TV to run into problems with the data the set collects. In late 2013, a UK IT consultant found his LG TV was gathering information about his viewing habits.
Publicity about the issue led LG to create a software update which ensured data collection was turned off for those who did not want to share information.
