I know about these but I kept it simple and performed another (inadequate)
turing test.
Computer can add as the best and it won't be long till they can read those
images too (if they can't already).

I made the decision to publish the source code so I would write more secure
code.
I think secure code that solely relies on obfuscation is not good enough.
Code is really secure if a hacker can't break it even if he knows how its
implemented.

I rewrote the addition test with a session and a measure to avoid replay
attacks.
Can you think of another way to circumvent the test other than to parse the
file and let a computer to the addition?
