A Hybrid Image Encoding Technique with DCT and Mosaic based Segmentation

Abstract

Embedding the information in cover image is always an interesting research issue in the field of image steganography. In this paper, we are using a hybrid model with compression, data encoding and image mosiacing technique. Image (pixel values) can be compressed with efficient DCT technique, Data can be embedding in to cover image without losing the data integrity with LSB technique, because usage of significant bits of the image may damage the image and image can be parallel segmented without losing pixel integrity and combined at receiver end with improved noise free image mosaicking technique. Our experimental analysis gives more efficient results than traditional approaches.
