What if we could simply move some pictures and tell a story only we know to login?
The Idea: A Semantic Story
Instead of arranging arbitrary alphanumeric characters in a complex order (like ‘DjK7-Uikk2’), you will see a group of your favorite pictures and select some of them to tell a story that is meaningful and memorable for you.
This Demo only uses the factor “knowledge” (the secret move pattern). PASSPOL consists of several factors which are combined to a highly secure and unique cryptographic token which is also hard to break by brute force or guessing attacks.
Try it!
This is the public semantic story behind the pattern:
Alice sails with Bob to an island finding a secret treasure. Alice got the key, and Bob threw it into the sea.
Now enter the secret move sequence, which can be found in the video.
It looks like a game..
..but behind the scenes, the system generates a unique statistically equal high entropy pattern of characters. Therefore, together with other technical factors not used in this demo, you handle a usable strong “password”, you use it quickly and conveniently and it is strongly memorable without extensive practice. PASSPOL uses the so-called Dual-coding theory to enable a real human-centered design.
The PASSPOL pattern used in this demonstration represents about 75bits of entropy and equals a strong textual password. Enabling all features of PASSPOL makes it possible to use much higher entropy.
