Is there anything nowadays that is secure? I’ve blurred images in the past (mainly screen shots ∗) in order to cover information that I didn’t want published with the image. An interesting post on why blurring sensitive information is a bad idea might be a bit far fetched for most of us, but I consider it important to know that accessing information I considered removed actually is possible. The bottom line? Don’t blur: color over them with a thick black box. ∗ I recall a partially-blurred screen shot that I sent Michael once; he phoned me to say that my email address was visible when the image was viewed at a large magnification. :-(
