Joint Watermarking and Lossless JPEG-LS Compression for Medical Image Security

- We propose the first Joint watermarking-compression scheme based on JPEG-LS in its lossless mode.
- The proposed scheme allows message extraction from the compressed bitstream.
- The proposed scheme does not require the watermark reader to decompress the bitstream even partially.
- Achieved capacities can provide different watermarking based security services.
- Our scheme introduces an acceptable distortion for ultrasound images.
