When using steganography to hide messages, why is it better to change the least significant bits of an image, and how is this detected?
What will be an ideal response?
Changing the most significant bit (highest priority bit) on the left will cause a greater change in the pixel's color than changing the least significant bit. Generally speaking, only the last two LSBs in an image can be changed without producing a noticeable change in the shad of the color a pixel displays.? To detect a change to the last two LSBs in a graphics file, a steganalysis tool must be used.
