scripts default iconSimple watermark embedding system (Scripts) Publisher's description

Simple and easy to use application for embedding

Simple and easy to use application for embedding
and extracting hidden data in images.
Application implements simple author algoritm
using least significant bits of chroma components
of image pixels for injecting watermark data.


1. Currently only fixed size of images (400x300) is supported
2. Implemented algorithm isn't robust against compression; at future time adding error correction scheme is planned; meantime 2-bit or even 3-bit (quality degradating) LSB embedding is proposed
3. Because of manipulating chroma components, only color images are supported (no grayscale images or pure white for example)
4. Supported input image formats are JPG and BMP. Output images are generated in BMP format. Also in current working directory only!

System Requirements:

MATLAB 7.9 (2009b)
Program Release Status: New Release
Program Install Support: Install and Uninstall
