Hi guys

On a shared touch screen device what do you feel is the best way for one end user to prevent another user accessing certain areas of content?

I am in a little light hearted debate at the moment as to the best way to achieve this centric on whether the traditional character based password method is still superior to a gester, say, the continuous selection of a series of squares on a 4 x 4 grid.

Personally I am erring to the side of the traditional character based password being superior. This is because i believe that a user generated password would be easier for the user to remember over a user generated symbol, which in my mind is what the continuous selection of a series of squares on a 4 x 4 grid fundamentally is.

Maybe I am wrong. What do you guys think on this subject?

Opposite to your preference, I'm more a fan of  gesture methods since they're more related to human symbolism or personal metaphors and therefore easier to remember than numbers sequences. I personally have experienced that benefit  with the unlock keys gestures of the android vs the native iphone unlock pass. However, we need to wait until the gesture research tell us if it  brings more combination possibilities for allowing security and uniqueness or if cultural or psychological facts can make gestures easier to predict.
