Are you using the Tor onion routing system and you are still paranoid about the security of your connection? Then you may consider to go for ‘Dead Drops’ the most underground network on this planet.
Dead Drops is an anonymous, offline, peer to peer file-sharing network in public space.
USB flash drives are embedded into walls, buildings and curbs accessible to anybody in public space. Everyone is invited to drop or find files on a dead drop. Plug your laptop to a wall, house or pole to share your favorite files and data. Each dead drop is installed empty except a readme.txt file explaining the project.
Dead Drops is open to participation. If you want to install a dead drop in your city/neighborhood follow the ‘how to’ instructions and submit the location and pictures.
