Can anyone help me how to hide 3 bits of n-bit message into 3 LSB bits of cover image? I would really appreciate your help. Thanks in advance..?

Embedding algorithm: Input:cover image,secret image output:stego image 1. Obtain Huffman table of secret message/image. 2. Find the Huffman encoded binary bit stream of secret-image by applying Huffman encoding technique using Huffman table obtained in step 1. 3. Decompose the cover image by using Haar wavelet transform 4. Calculate the size of encoded bit stream in bits. 5. Repeat for each bit obtained in step 4 (a) Insert the 3 consecutive bits into 3 LSB position in each DWT coefficient of the selected sub-band. 6. Repeat for each bit obtained in step 2 (a) Insert the 3 consecutive bits into 3 LSB positionin each DWT coefficient(excluding the first four coefficients in each sub-band) of the selected sub-band. 7. Repeat for each bit of the Huffman table (a) Insert the 3 consecutive bits into 3 LSB position in each DWT coefficient of the selected sub-band. 8. Apply inverse DWT. 9. End.
