Example: Audio Embedding
Let’s assume an audio file had the following 8 bytes of data in it somewhere: 180, 229, 139, 172, 209, 151, 21, 104
In binary, this would be:
10110100-11100101-10001011-10101100-11010001-10010111-00010101-01101000
If we wanted to hide the byte value ‘214’ (11010110), we use the least significant bit from each byte to hide our byte:
10110101-11100101-10001010-10101101-11010000-10010111-00010101-01101000
The changes result in the following bytes, which are so close to the originals that the difference will be inaudible:
Modified: 181, 229, 138, 173, 208, 151, 21, 104
Original: 180, 229, 139, 172, 209, 151, 21, 104
