Scientists Release Working Prototype Of CAPTCHA-Based Password Assistant

Posted by timothy on from the holding-out-for-retinal-scans dept.

An anonymous reader writes "Last year Slashdot ran a story on scientists from the Max-Planck-Institute for Physics of Complex Systems in Dresden, Germany developing a novel method to improve password security. A strong long password is split in two parts; the first part is memorized by a human, and the second part is stored as a CAPTCHA-like image of a chaotic lattice system. Today, after a year of work, the same group at Max Planck Institute released a working prototype online, where everybody can try this technology to encrypt files (Java plugin required)."

    Actually, this is better -- it prevents brute-force attacks unless you have a very, very good method of solving CAPTCHAs. Even if you can solve the CAPTCHA, though... there's no guarantee that you'll get a good CAPTCHA based on the password you're trying.

    Plouf - we need these permissions in order to read the files :-)

    As far as self-signed goes - we did not want to spend $500 on a chunk of bytes :-) Please trust us :-))

    Cdxta: This is exactly true - the purpose of the algorithm is to introduce something that in your language would be described as false positives.
