An Overview of Image Invisible Watermarking

Abstract

The proposed paper addresses all the concepts related to invisible watermarking systems for securing data transmission. Watermarking refers to the technique of embedding information within messages and network control protocols used in network transmission. Image invisible watermarking techniques can be divided into two groups: Image Domain and Transform Domain. Image domain techniques encompass bit-wise methods that apply bit insertion and noise manipulation, and are sometimes characterized as "simple systems." Invisible watermarking is lossless, and the techniques are typically dependent on the image format. Invisible watermarking in the transform domain involves the manipulation of algorithms and image transforms. Least Significant Bit (LSB) insertion is a common, simple approach to embedding information in a cover image.
