      Someone could then set their password to equal: 1. where they were born, 2. where they work, 3. where they went on vacation last year.

      Of course, there wouldn't be any prescribed formula for choosing the locations, so a user could choose any number of locations for any reason. They might even choose "..that place where they put that thing that time [youtube.com]."

        Incidentally, I love that clip, as it has the single realistic 'hack' in the entire movie. If you're on a phone where you can't dial at all, hang up the phone, take it back off the hook, click the switchhook ten times, which dials '0' in rotary, and you get an operator, who can dial for you.

            It can be done, but why? It's much easier to just ask the operator to dial for you.

            The fun thing about asking the operator is that even the smartest 'pen register' tap can't figure it out. Even if they can do pulse dialing, they'll just see you dialing 0.

            It sounds silly, but in actuality jail phones often have such a device on them.

            • To the best of my knowledge, all jails record phone calls. I'm sure they intercept the dialed number as well as the calls. Getting the number the technical way, especially when it's tapped out by hand, is harder than just listening to the operator saying "Operator, please connect me to 212 555 1212".

              They have a bit less interest in the phone number than the actual conversation.

    It's not half as dumb as the summary makes it sound.

    For security, what matters is the keyspace and the likelyhood of guessing correctly. The keyspace easily competes with alphanumeric passwords. It is dramatically reduced by the assumption that people will pick places with meaning to them, which means places they've been to. Nevertheless, it should measure up to passwords in security.

    Different from passwords, though, the human mind is pretty well equipped to recall specific places. Arbitrary alphanumeric combinations, on the other hand, are amongst the most difficult things to remember and recall.

    Looking at Google Maps the area covered by the windshield of my car is about five places after the decimal point of precision in both lat and long. That is about one square meter and as precise as you could realistically expect users to be. That would mean each location would give you 2+5 digits for the lat and the long, a total of 14 digits for a password. That's 10^14 possibilities. For comparison a password made up of random characters (lower, upper, digits, special) for a total of 95 total possible choices would need to be seven characters long to have about the same entropy (67 trillion vs 100 trillion).

    Seven character random passwords are ok, but certainly not uncrackable. You could argue that letting the user choice several spots would greatly increase the entropy, but realistically the user is going to pick spots close together. Not to mention you could probably cut down on the possible locations with something similar to a dictionary attack, i.e., eliminating the vast expanses of nothingness that are unlikely to be chosen (like oceans, and deserts). Lastly, it relies too heavily on the mapping service. What happens when they update their images and your landmark disappears or moves slightly?
