1 Answer 1


The image at the top is

the XOR of the circles below, each suitably offset.

If we

label the "pixels" A-Z from top to bottom, and then A-Z from left to right, and read off the y-then-x of the circles' centres, starting with the largest,

we get


At this point I thought there was more to do, but Deusovi informs me in comments that

this isn't an instruction to figure out the "registered owner" of some particular thing (e.g., the trademark to a logo that resembles the original bitmap); rather, the answer is the words REGISTERED OWNER.

The following diagrams may or may not clarify things a bit.

the circles are numbered from smallest to largest, which turns out to be the wrong order. Also, #7 is clipped at the top because it was only part-way through the solving process that I realised it would be helpful to work with an image with some extra "margin" on all sides.
