For that the best way is to blur the image than use a mask to
select what parts should come from what image.
That is
load image
create a blured image
create a seletion mask (white on black) (also blurred)
and do a masked 3 image composition...
convert logo: \( -clone 0 -blur 5x2 \) \
\( -clone 0 -gamma 0 -fill white \
-draw 'rectangle 220 180 320 280' -blur 10x5 \
\) -composite logo.png
A better solution however is to somehow do a variable blur, where
some mask is used to control the overall amount of bluring.
However this is not currently posible with IM, though it is a feature
that I myself have been wanting.
Fred Weinhaus has however developed a multi-level composition blur
script called "variableblur" to do this in a rough way until some type
of better masked blur operator can be developed.

You can also pixelate the image area instead of blurring....
Like they do to fuzz out 'naugthy bits' and faces on TV news.
In this case lets try to protect anonymity of the IM wizard. :-)
convert logo: \( -clone 0 -scale 10% -scale 1000% \) \
\( -clone 0 -gamma 0 -fill white \
-draw 'circle 400,200 440,200' -blur 10x5 \
\) -composite logo.png
Again the drawn mask (a blurred circle this time) is used to
definate and limit the area that should be pixelated.
