Security of data or image is one of the important steps in the enormous domain of multimedia. Encryption of images is well known technique to protect the information present in the image in order to maintain the confidentiality, authenticity and integrity of images. This paper proposed a method for image encryption based on the Huffman coding and homogeneous transformation of pixels. Huffman coding is used to protect the huge amount of data with good visibility and no loss of information. Encrypted image generated by the proposed work is quite different from the original image.
