The method doesn't employ any tracking elements and works when used in anonymous
|
|
|

networks like TOR\@.

The method relies on Optical Character Recognition (OCR) capabilities of human
|
|
|
|
|
users. OCR technology is becoming increasingly sophisticated which would render
|
|
|
|
|
this method ineffective in the future.

Without OCR, this method can be bypassed using human-powered CAPTCHA farms with

Since the method relies on OCR, it is inaccessible to users with visual and

Success and failure are absolute states in this method. A misaligned object
|
|
|
|
|
results in failure while a properly aligned object succeeds. But when using
|
|
|
|
|
employing CAPTCHA farms for circumvention, the method fails absolutely.
|
|
|
|
|
|
|
|
|
|
The method uses only the object alignment in its decision process. No other
|
|
|
|
|
external factors are involved.
