Nowadays, not even humans can pass the Turing Test, thanks to annoyingly hard to read captchas. PlayThru aims to stop that by allowing humans to play a simple game for authentication. Current computer vision algorithms in spam bots can figure out letters and type them in without too much trouble (well, maybe not captcha’d letters), but now the task has become much harder, as the bot will need to determine what the task is and actually do it. +1 For the humans!
Hey! I am a human!
