Dynamic Image Watermarking using Hybrid DWT Compression and Decompression Techniques

Abstract

This study presents an innovative information hiding approach that utilizes lifting schemes to seamlessly embed data in color images. The efficacy of this technique lies in achieving successful extraction of concealed data with a high level of integrity. Current preferences favor the use of digital image files as cover files for concealing additional digital content containing secret messages or information. Different digital media streams can function as cover streams for secret messages, with watermarking emerging as a prominent technique for copyright protection. The paper introduces a novel method for encoding secret messages using wavelets. The wavelet technique dissects the stream into high and low-frequency components, referred to as details and trends
