Smart home "service in place" but can not ignore security and privacy

Remotely check the situation at home, use sound instead of remote control to control home appliances, and connect various devices to each other to automatically adjust work status. People have dreamed of living in such houses for a long time. In recent years, the development of the Internet of Things and smart homes have made such illusions a reality.

According to the data released by Gartner, a US research and consulting firm, by 2016, a total of 339.1 million pieces of connected devices were put into use in the “smart home” area, which was nearly twice the number in 2015. However, while enjoying the services brought by smart devices, one cannot ignore a very important issue: security and privacy.

Please note: When you are talking about topics that contain personal or other sensitive information, they are also collected as data and transferred to third parties.

This is the sentence found in a web magazine in the privacy policy of Samsung Smart TV in February this year. Its discovery caused a sensation in the social network. A user on Twitter even compared this passage with the fragment in the novel “1984”, implying that it violated user privacy.

After this matter was exposed, Samsung quickly modified the relevant regulations. The related content that we saw here is this:

Samsung only collects your interactive voice commands when you ask Smart TV to make specific search commands. To complete this command requires you to press the start button of the remote control or the screen and speak into the microphone of the remote control. ... You can stop speech recognition data collection at any time in Settings, but this may affect the use of some speech recognition features.

In 2013, a user using LG Smart TV found that his viewing habits information was actually collected, provided that he had already turned off the relevant features.

Later, LG made related repairs, but after a few months it released a revised privacy policy (still in use), which wrote: "In order to get all the services of smart TV, you must agree with us. Privacy Policy allows your LG Smart TV and our system to have more information exchanged." Is such a strong attitude that people can still watch TV quietly?

This year, Synack Security's experts investigated 16 home automation devices, including cameras, home automation controllers, and thermostats. But the results were disappointing. They found that almost every device was very vulnerable to invasion. The reason is that many people do not modify the original password and encrypt the data.

By exploiting the vulnerabilities of these devices, intruders can collect various information about the target, understand their behavior and habits, and threaten their privacy and security.

In addition, there are foreign technical articles mentioning that there is now an advanced tracking technology. TV advertisements can send high-frequency sounds (which people can't hear) by sending out smart phones, laptops, or microphone-opened devices. Track your online behavior on your device.

However, the world in which all things will eventually be connected is not terrible; it merely requires people to have a new way of seeing the world and the correct use of smart devices. Perhaps in the future, knowing how to protect and use personal data will become as important as literacy. However, prior to this, the company's "doing no evil" and perfect laws became even more important.
