Example of Embedding in Imagery

• An image may have the following three pixels (9 bytes) in it somewhere:

• (01010010, 10010110, 10100100)

• (10110100, 10010001, 01001110)

• (10110110, 00101110, 11010001)

• If we wanted to hide the letter “A” (131 or 10000011), we would use the least-significant bits of each byte:

• (01010011, 10010110, 10100100)

• (10110100, 10010000, 01001110)

• (10110111, 00101111, 11010001)
