Captcha

[gdmk]

[kancik]

jakiś zaawansowany ocr pewnie to by rozszyfrował Ale jest przeciez kilka innych technik z których można pomyślnie korzystać

[Kartofelek]

Tak sobie pomyślałem, że można by podebrać taki obrazek, zamontować go do canvasa i za jego pomocą wykryć pxl itp. Wolne bo wolne ale dało by rade

Pomysł z canvasem byłby realny gdyby te captcha nie miały różnych struktur.

Nie znam się na tym zbyt dobrze, ale chciałbym coś zasugerować.
<input type="hidden" name="tid" value="6316581">
<input type="hidden" name="buy" value="OK">

Widać, że jest ukryty przycisk OK. Ciekawe co by się stało, jakby się go wywołało

Znalazłem źródło w java script odpowiadające captchy
