Morse code in a pop song

posted January 2015

Amazing article on the verge about how the army created a song hiding a message ("19 people rescued. You’re next. Don’t lose hope") so that hostages of the FARC could hear it on the radio.

This is a genius idea for concealing a message! Not really crypto, but kinda cool none the less. I knew about Stenography and I also posted about transforming your message into spam as a way of hiding your message, but this is cool on a different level. Even the song is catchy ^_^

There was this disturbing video of a captive soldier in a North Vietnamese prison who when forced to do a fake interview, blinked the Morse Code 'T-O-R-T-U-R-E'.

Well done! You've reached the end of my post. Now you can leave me a comment :)
