Geographical passwords could solve the password catch-22, says a security researcher. Computer scientist Ziyad Al-Salloum of ZSS-Research, writing in the International Journal of Security and Networks, claims it's easier to remember places than numbers or words. The system asks users to draw a boundary round a favourite place which is then hashed. According to Al-Salloum "Proposing an effective replacement of conventional passwords could reduce 76% of data breaches, based on an analysis of more than 47,000 reported security incidents," he explains that a whole-earth map might have 360 billion tiles at 20 degrees of "zoom," making geographical passwords essentially unguessable. [1] "http://esciencenews.com/articles/2014/02/16/geographical.passwords.worth.their.salt" [2] "http://xkcd.com/936/" P.S. I assume there's some overlap between readers of this group, soylentnews and Slashdot, so I'm going to try to avoid posting stories already covered on those sites. -- View this thread at http://squte.com/node/4490

"tdk" <forum.tdk@squte.com>: > Geographical passwords could solve the password catch-22 Interesting. Essentially, this sounds as though the servers already know everything about you when you connect so a password is redundant. The ultimate antithesis of privacy. > P.S.

Do you think those sites are going to return the courtesy? Marko

The globe does provide more diversity of choice but I suspect most users would unconsciously choose a place they have a connection to. Rather than choose some random mountain in Kyrgyzstan they are going to choose something familiar, and that provides an attack route when trying to crack their password. --

If the password system allows for arbitrary shapes, there's additional protection even if the user chooses his home or workplace as the pass-site. There's no way to guess "my college campus, but just leave out the terrible cafeteria at Comp-sci faculty". Of course, users should be educated to avoid using basic shapes like squares or hexagons, just as they now know to avoid using their birth date or a number sequence. Oh, wait...

Oh, wait... I'm remembering, too, that Americans (at least) have increasingly lousy geography skills. It was in the midst of the last Iraq invasion that some researcher discovered a surprisingly high number of Americans couldn't find Iraq on a map. That's depressing. I'm all in favor of a substitute for passwords, but we're not there yet, and the new craze of fingerprint scanners doesn't yet seem to be an improvement. I'm waiting for "drop of spit" technology, where the sensor reads your DNA to log you in :)

I'm not sure everyone wants to license and store all that GIS data just to draw pictures on it. -txm

Thus, even if two users pick the same | place as their geographical password the behind-the-scenes password | settings is unique to them. `---- So we're back to a string of characters stored on a server, which has to be matched with another string of characters supplied by the user's computer. The security of the password has nothing to do with how complex or obscure the selection process was, only with the difficulty of guessing or acquiring the string of characters actually used. It isn't clear from the linked article how the user is required to enter the password each time they want to access the protected data or service. If they have to use the same map and pick precisely the same spot and replicate the shape they drew around it the first time, the system will have to include a fair amount of leeway for inaccuracy in those actions - and there will be a lot of data being exchanged and possibly intercepted each time. Both those aspects compromise security. If the user merely has to store the final character string and retransmit it when required, then anyone who can access that store has immediate access to whatever the password is protecting - we're back at the note taped to the back of the mouse pad, in effect. > P.S.

That may be a false assumption. -- -- ^^^^^^^^^^ -- Whiskers -- ~~~~~~~~~~

> I don't see how this is anything more than just another way of generating a password; Yes, that's all it is. The argument is that since memory is a limiting factor for the 'guessability' of passwords, and people remember places better than words, this will lead to better passwords. > the password is then "salted" by adding a string of hidden random characters that > are user-specific I didn't understand this. Salts are used to prevent pre-compiled dictionary attacks and are old news; I suspect the writer was just confused about what was new. > a lot of data being exchanged and possibly intercepted each time Well that�s a potential problem whatever kind of password is being transmitted to the server. A bigger issue is that the user will have to send data to a third party server (say google maps), and shoulder surfing will be easier. regards tdk -- View this thread at http://squte.com/node/4490#comment-10793
