nah. I'll stick with alphanumeric.
It makes psychological sense, but it's still silly from a security perspective. It will just encourage people to pick even MORE EASILY guessed things, such as "Windows---Heart---Bill Gates---START BUTTON"
I would have to agree with most of you. But I am wondering, how many pictures is the user allowed to pick from. Knowing microsoft it will probably be around a couple hundred. Ok. Will that same couple hundred be on every windows computer? Not so good. Or are you going to be able to use your OWN pictures? More secure, i would think. I can see this thing becoming secure, or as secure as easy-to-guess passwords. Time will tell.
I will always use to good ole' standby for a password. "letmein". <grin>
On the serious side. The more complex the better. I believe alpha-numeric will always be better and harder to crack than click-a-pic. I mean how hard would it be to crack a few mouse clicks? Compared to a password such as: @$%$97$$@3566)(**&&(*!@!>~++hP:'"% encrypted to a 128 bit or greater key. Hmmm. Tough choice? NOT. I'll stick with my good old passwords. Leave it to M$ to try and goof things up.
this is not a new idea... i forget the exact number of image in sequences the brain can remember but it's quite a few...
the interesting question to me would be implementation...if image 1 = A and image 2 = b from a stock of x number of images... well...not so interesting but....if could you pick your own images...hmmmmm
how bout this..
develop some kind of key based on pixel patterns in each image..given that the each picture could be virtually unique
even i you knew the picture was a picture of my cat...was it taken in doors, in low light, did i manipulate the color...etc...with a 32kbit color depth you have a lot of 1's & 0's to play with...
...this could be like some kind of "pixel dna sequence" (pds)?
then have several image pds's in a string you'd have to know each pds and it's correct order...would think it could be very strong...and user friendly...which would be a first...
thoughts???
(heading to the patent office now...hehe)
Forget that, those whack crazies at microsoft didn't just come up with this. Plus, it'll be even harder for the average computer user to remember a series of pictures. The human brain remembers things in 'bits' and 'chunks', and it's much easier to chunk a string of alphanumeric text, than it is chunk a series of pictures located all over the screen in a different order. I think it's highly unlikely that this will catch on.
Agreed. Human psychology dictates that this is even less secure and user-friendly than text-based.Quote:

I mean, if there's a Windows logo amongst the pictures, how many millions of users will just use that (And Only That) as their "pass-sequence"??
Whereas, if its text based, yeah it could be 'password', or 'letmein' or any of a multitude of others... i.e. text is always gonna be more secure, based on limitations of the human memory.
Hotspots.
Images as passwords are not only about image sequences with several different pictures involved. They do develope a method were you freely can choose lets say five spots on one picture (not marked spots). If you had a 640*480 image with 72 dpi in resultion it would be a lots of numbers if every pixel was a number and every hotspot was approx 10 pixels wide and high. This method should not be unbreakable but lots worse to crack then traditional passwords. The problem would maybe be to develope this hotspots in a picture, but they already have methods for it.
Just wanted to share..

if that was the case then we'd all be running dos and unix command lines...Quote:

humans are absolutely image based....in fact what is text but an image representing a concept...
the maximum sequence of alpha numerics most people can cope with without "chunking" (splitting the sequence up") is 7 characters...
i'm doing some googling right now...i soon as i can fiind the right question to ask...i'll post back...
Found some more information on this topic.

But then later on in the article:Quote:
People could use any image, the more complex the better, or even video, according to Kirovski. The images would have to be doctored to work with software that could convert pixels to numbers and encrypt them.

In general, it might be more secure, he said, "because people choose such lousy passwords."
