You want to send your $12-$digit credit card number to your friend, and you don$$t want anyone to

hack it$,$ so as a DSP engineer, you planned to use Steganography to send your card number.

Hint: write an individual letter on an image and then Hide these $12$ different images in a single

RGB image. Use $4$ bit encoding for image $($aka$,$ map of Pakistan$)$ in which you will encode. Save

an image containing a card number in a single bit of each band of map of Pakistan. $3$ bands and $4$

bits will encode these $12$ images. Also write a code of decoding and extracting the digits of credit

card.
