For every pixel of a block, least significant bit (LSB) substitution is applied on two LSBs and quotient value differencing (QVD) is applied on the remaining six bits.
Buzzwords in my world include: privacy, context, youth culture, social media, big data.
I use this blog to express random thoughts about whatever I'm thinking. As far as Carmen’s concerned, she has nothing to hide from her mother so she’s happy to have her mom as her ‘friend’ on Facebook.
Social steganography is one of the most common techniques that teens employ.
They do this because they care about privacy, they care about misinterpretation, they care about segmented communications strategies.
Of course, Carmen’s mom doesn’t always understand the social protocols on Facebook and Carmen sometimes gets frustrated.
She hates that her mom comments on nearly every post, because it “scares everyone away…Everyone kind of disappears after the mom post…It’s just uncool having your mom all over your wall.But that doesn’t mean teens aren’t experimenting and learning. The more they live in public, the more I expect them to hide in plain sight.In fact, I’d expect that they’re learning more nuanced ways of managing privacy than any of us adults. And they know that technical tools for restricting access don’t trump parental demands to gain access.So they find new ways of getting around limitations. Ancient methods Steganography is an ancient technique where people hide messages in plain sight.In order to avoid a freak out, Carmen will avoid posting things that have a high likelihood of mother misinterpretation.This can make communication tricky at times and Carmen must work to write in ways that are interpreted differently by different people.That’s just lame.” Still, she knows that her mom means well and she sometimes uses this pattern to her advantage.While Carmen welcomes her mother’s presence, she also knows her mother overreacts.She’s communicating to different audiences simultaneously, relying on specific cultural awareness to provide the right interpretive lens.While she’s focused primarily on separating her mother from her friends, her message is also meaningless to broader audiences who have no idea that she had just broken up with her boyfriend.
