Social Media Safety

During the presentation, I learned that any of the media is not 100 percent safe. Some people can get our information which we shared on the internet, even they can find something privacy. They have ability to hack in our camera and then they will know everything happened in our living room. That's sounds horrible but these phenomenons really exist.
To keep my safety of media, I sell my phone and computer. If I want to protect my students, I will sell their phones and computers.
In my opinion, the presentation is really useful for helping us to be aware about we are kind of exposed.
