Improved Image Steganography Algorithm using Huffman Codes

Steganography promises confidentiality of data being transmitted between two parties by hiding the very existence of the data. It helps to achieve secure transmission of data over a network. This research paper provides a technical introduction of image steganography and its implementation using Least Significant Bit (LSB) technique with Huffman Coding. It focuses on the use of Huffman Coding Algorithm to minimize the amount of bits to be embedded into the carrier in order to achieve efficient image steganography.
