no one up till this point had looked at

no one up till this point had looked at the accelerometer the accelerometer is

the accelerometer the accelerometer is

the accelerometer the accelerometer is the thing that determines the vertical

the thing that determines the vertical

the thing that determines the vertical orientation of of the smartphone and so

orientation of of the smartphone and so

orientation of of the smartphone and so they had a simple setup they put a

they had a simple setup they put a

they had a simple setup they put a smartphone next to a keyboard and they

smartphone next to a keyboard and they

smartphone next to a keyboard and they had people type and then their goal was

had people type and then their goal was

had people type and then their goal was to use the vibrations that were created

to use the vibrations that were created

to use the vibrations that were created by typing um to measure the change in

by typing um to measure the change in

by typing um to measure the change in the accelerometer reading to determine

the accelerometer reading to determine

the accelerometer reading to determine what the person had been typing now when

what the person had been typing now when

what the person had been typing now when they tried this on an iPhone 3GS this is

they tried this on an iPhone 3GS this is

they tried this on an iPhone 3GS this is a graph of the perturbations that were

a graph of the perturbations that were

a graph of the perturbations that were created by the typing and you can see

created by the typing and you can see

created by the typing and you can see that it's very difficult to tell when

that it's very difficult to tell when

that it's very difficult to tell when somebody was typing or what they were

somebody was typing or what they were

somebody was typing or what they were typing the the iPhone 4 greatly improved

typing the the iPhone 4 greatly improved

typing the the iPhone 4 greatly improved the

the

the accelerometer and so the same

accelerometer and so the same

accelerometer and so the same measurement produced this graph now that

measurement produced this graph now that

measurement produced this graph now that gave you a lot of information while

gave you a lot of information while

gave you a lot of information while someone was typing and what they did

someone was typing and what they did

someone was typing and what they did then is used Advanced artificial

then is used Advanced artificial

then is used Advanced artificial intelligence techniques called machine

intelligence techniques called machine

intelligence techniques called machine learning to have a training phase and so

learning to have a training phase and so

learning to have a training phase and so they got most likely grad students to

they got most likely grad students to

they got most likely grad students to type in a whole lot of things and um to

type in a whole lot of things and um to

type in a whole lot of things and um to learn to have the system use the machine

learn to have the system use the machine

learn to have the system use the machine learning tools that were available to

learning tools that were available to

learning tools that were available to learn what it is that the people typing

learn what it is that the people typing

learn what it is that the people typing and to match that up with the

and to match that up with the

and to match that up with the measurements in the accelerometer and

measurements in the accelerometer and

measurements in the accelerometer and then there's the attack phase where you

then there's the attack phase where you

then there's the attack phase where you get somebody to type something in you

get somebody to type something in you

get somebody to type something in you don't know what it was but you use your

don't know what it was but you use your

don't know what it was but you use your model that you created in the training

model that you created in the training

model that you created in the training phase to figure out what they were
