\n*What it means to brute force a password. Try it out yourself here<\/a>. Their algorithms for what character(s) to try improved dramatically once they realized typing in a random characters was taking too long.\n

\n*CV Dazzle<\/a> aka hiding from computer vision. Here we presented the kids with a tablet with OpenCV installed that would draw a box around a face when it detected one. The participants were given pieces of black and white flexible plastic to put on their faces to see if the computer would recognize their faces. We also had Phuong Vu\u2019s CV-Dazzled code<\/a> running to generate CV dazzle camouflage in order to give the kids a sense of what needed to be covered for them to be hidden.\n

\n*Public Key Encryption activity<\/a> with 2 sets of keys and locks and a case.\n

\n*Diceware<\/a> or using dice as a hardware random number generator to generate a secure password. Participants rolled 5 sets of dice 7 times<\/a> to produce a 7 word passphrase.\n\n \n\n\n\n
