    New Robot Vs Human Validation: Slide To Fit Captcha

    Link: minteye Products

    I like the idea but I found that I could pass as human even if I had not [deliberately] fully straightened the image offered. A work in progress I guess.

    Recaptcha, digitising books. How, though? Because surely to confirm it's correct it's needs to verify against a source... (I've known this for donkies but never looked this bit up)

    This is covered in the video at about this point:

    If 100 people type a fuzzy bit of scanned text as jumper and 2 type it as slumper then it's probably jumper.

    What about the majority of the text though? I mean the 1/100 words that can actually be typed?
    I've always thought it was a secret ploy - no books are being decyphered, the NHS are just conning us into translating doctor's notes for them.

    This won't stop the CAPTCHA farmers.

    Not to mention fundamentally flawed...

    Breaking the MintEye image CAPTCHA in 23 lines of Python

    In conclusion, it would seem this method of image based CAPTCHA is fundamentally flawed. A simple ‘swirl’ operation will always be detectable by this method, no matter the image being swirled. The increased sharpness also gives the game away – an FFT or autocorrelation could easily be used to detect this change in sharpness, just like autofocus algorithms.
