Shock! Your "privacy" may be being eavesdropped on smart TV

Regardless of the collection method, these voices are uploaded to a third-party agency, and text conversion and semantic analysis is performed on the cloud server and then transmitted back to the television. However, after this, it will not be known whether these voices will be deleted or used for other purposes.

In daily life, many users' search content is monopolized to advertisers, enabling them to push relevant advertising content according to the user's search preferences. Although some manufacturers will emphasize in the statement or privacy protection policy that they will not retain or sell the customer’s voice data to third parties, more manufacturers do not explain the collected voice data. They only wait for the incident to rush to plead guilty. On February 6, TV maker VIZIO was charged by the US Federal Trade Commission (FTC) for improperly collecting user ratings data and providing such information to third parties.

This kind of behavior of reselling private information is still hidden under the shadow and it is difficult to be supervised, tracked and effectively attacked. Users often feel that their personal information is leaked, but it is difficult to provide valid evidence. Even if the leak is confirmed, companies often throw pans to “interns”, or declare a “strengthen management” of the matter, it is difficult to get legal supervision, and it is impossible to implement compensation on the victims. Privacy is "hijacked", but consumers can only get a verbal security check.

In fact, even if the vendor does not resell the content of the voice, its security is still worrying. In particular, Internet of Things products such as emerging intelligent voice toys, the information stored in their cloud servers may not only be stolen under the attack of hackers, but also may send audio, hacking software, and other data to the user to make them more available to users. Key private information.

Security researcher Jakubowski once commented on these cloud servers: "Through this information, you can easily find a person's home and company address. It is only a matter of time before their servers are attacked."

Nowadays, after voice control, smart appliances turn their attention to the call. According to some sources, Amazon’s Echo smart home device and Google’s Google Home device are expected to join the call feature this year. Voice and even video calls will be made through TVs and refrigerators. If the call function is applied to a smart home on a large scale, the privacy of its content will be greatly enhanced. Daily information and even the user's appearance and family will be involved.
