I am a 22 year old kid and I can't tell you how many times this has happened to me. It even happens with snap chats actually, because of the apps that allow you to save a snap. I am noticing however that there seems to be a strong correlation between household income and internet behavior. My wealthier friends all have pristine online images, while the poorer ones tend to share more.

I'm pretty sure Snapchat notifies you if the other party takes a screenshot of your photo, though.

  They notify you but that other person still has the photo. It's better than nothing but it's not that helpful.

    See my post above, its an actual app.

    Unless you have a jailbroken phone...

  There are actual apps you can download that allow you to save a photo or video, not just the screenshot. I'm actually pretty baffled that people still don't know about them. Renders snapchat useless.

    The concept of Snapchat is useless - it's literally DRM. It will work well enough for some folks, but fundamentally it simply isn't technically possible. At least not without a "trusted computing" model with remote attestation and so on.

      No, its fundamentally impossible: http://en.wikipedia.org/wiki/Analog_hole http://en.wikipedia.org/wiki/Analog_hole

        You can prevent the actual bitstream from being copied with "secure" hardware, and most such hardware includes systems that verify output devices. Of course nothing stops you from taking a picture or video of the screen, but that's not making a digital copy. (Although, with a high resolution scanner, you could read every pixel and reverse the encoding and possibly end up with the same bit-by-bit value.)
