Security threats in Smart Devices and Privacy Issues

A while back, an issue had come up with Samsung Smart TVs – that they collect whatever you speak in front of them and send the recording to some third party. This is done in the name of research so that Samsung can provide you with a better experience. This may be construed as an intrusion into your privacy. The post checks how dangerous it could be to converse with and among such smart devices, explaining security threats in smart devices. Is the Internet of Things too dangerous? Will this make one stop using smart devices? The Samsung case is being mentioned just as an example.

In case you are not aware of it already, the new model of Samsung that allows you to speak out commands to enhance your TV experience, also stores whatever else you speak in front of the smart device. Thus, if you are having a conversation with anyone while watching the TV, chances will be high that the TV will record everything and send it to the researchers – a third party that Samsung refused to name.

Once the recording reaches the researchers, the sound is converted to text and is stored in their database permanently. There is no thinking about what the researchers can do with the data, especially if you have been discussing your finances and gave out your card details or social security number etc.

Though Samsung had later clarified that the voice command feature is just optional and people can turn it off for security in smart devices, not many still know that they are being recorded.

If you wish, you can disable the voice control features on Samsung TVs by going into the TV settings > Smart Features > Voice Recognition > Off.

Smart Devices & Privacy issues

We had written about the dangers of Internet of Things – a while ago, and such issues confirm that security plus privacy is in danger, as users won’t know what the device is capable of doing. Folks thought that the matter would be limited to passwords and hacking. We talked how hackers can use your smart devices to launch a massive attack on any website. But this factor of smart devices recording what you do is a bit more worrisome than we expected. Not only the manufacturers, but hackers too can record your activities if your devices support such functions. You might already have read about hackers using your webcam and CCTVs to monitor your activities!

While the major issue is that those involved in programming do not think much about security at users’ end, there may be cases where programmers create modules that may act as a spy on your activities. Data is precious, and if there is a chance to lay their hands on collecting information about you, some companies will go too far.

How to improve Security in Smart Devices

There is not much you can do if a smart device manufacturing company tries to collect data. The only respite is that they’ll have to disclose it somewhere. If you read the entire device manual and TOC, you should be able to see what all data is being collected by the device.

Next to that, try and keep all the smart appliances in your home or office behind a Firewall. Since they’re vulnerable, using a firewall will make sure data won’t fall into wrong hands. You can use a Hardware Firewall (which I think is the best method) or a software firewall via a computer that’s always running.

To further increase security in smart devices, you can change passwords of the devices. Almost all smart devices have a default password that would be something like “0000”, “1234”, or “password”. Change it before you hook it up with rest of the network connected to the Internet.

Finally, buy products from popular brands that have to comply with the local laws. Chances of being cheated will be far less when you go for branded devices against local or low-cost devices as popular brands are forced to reveal what all data the smart device will collect. They cannot afford to lose their reputation worldwide.

At the moment, security in smart devices is both “ethical responsibility” of companies as well as “educational problem” on behalf of end users. In my opinion, companies involved in manufacturing should make the users aware about security issues in smart devices and give it a place in device manuals that will help in reducing problems related to privacy and security.
