Hybrid compression technique for image hiding using Huffman, RLE and DWT

Abstract

All kinds of information should be compressed before being sent over the web to save time & expense. The primary goal of this article is to create and construct a systematic and safe technique for encryption data that can be utilized to carry out a crisp compacting steganography technique. The approach may be used to reduce the volume of data sent with each transfer, allowing for faster delivery when utilizing sluggish web or taking up less space on a drive. The study offers a densification with steno approach that may be utilized to hide information with substantial privacy and complete invisible by combining RSA encryption technique with steganography expertise such as RLE (Run-length encoding), Huffman coding, DWT (Discrete Wavelet Transform) with LSB cryptographic technology. The very first process is based on RSA's ability to decode and encode private texts. The next process is compressing, which will include Huffman encoding based approaches to compress confidential stuff using efficient steganography technologies, RLE, which is a traditional approach to encrypt information, or DWT based on hatchbacks covering imagery by loss encryption in order to decrease the covering picture's size. The encrypted information will be implanted in the compressed cover picture using LSB (Least Significant Bit). When compared to various developed countries (Chen et al., 2021; Lakshmanan, 2020; Song et al., 2011; Yang et al., 2021; Ali et al., 2020) of the architecture that uses simulation results, this technique has a good ranking efficiency and a methodical system.
