Sorry if I'm being too thick here, but a blur filter needs information about the neighbour pixels. It can't operate on a single pixel alone (well it changes things pixel by pixel, but needs the neighbour pixels as input). If I can extract these neighbour pixels from the encrypted image, why can't I extract the image itself?
