Technical Creativity or Protection Technique?

Recently I came to know that many microchips have microscopic images hidden on them by the chip designers.

I don't know what is the intention behind it.But I doubt the security of our Information.As i came across this images i think they may have inserted some circuits which will send all the information stored in our computer.

We have to think about our information security.

Love?

Love is bitter and sweet, but which is more sweet the bitterness or the sweetness, none has spoken it.
