Computers are transparent by design. You cannot hide the bits in a computer. It looks like you can, but that is an illusion of process and representation. Most of us cannot break that illusion in practice so security often appears to work. Others do exist who made the pilgrimage to divine the fundamental patterns of the machine and can pry it open with great ease. The journey to do so does not take long and the visibility of bits are just under the surface. The machines were never designed to hide.
