Design new carriers hiding schemes:

  • Adaptive Minimum Error Least Significant Bit Replacement (AMELSBR) hiding scheme implementation for uncompressed images to minimize image changes
  • Work on HTML and XML schemes (using spaces and comments)


  • Copy EXIF information from source images to stego images
  • Support for grayscaled images
