Because of the phenomenal increase in online data sharing and transmission in the multimedia networks, data compression and security are under the limelight. This work proposes a new encoding scheme using Huffman coding for the encryption of data transmitted through a multimedia network. The proposed technique manipulates the Huffman coded compressed data without changing its compression ratio. The encoding is performed by a mutation process which in short generates multiple Huffman tree mutations by swapping the branches of the original Huffman tree, i.e., 0 to 1 & 1 to 0, using a checklist-rotation approach. Further, the decoding process is also explained briefly followed by validation of the proposed scheme by encrypting, decrypting and reconstructing different images.
