Towards practical self embedding for jpeg-compressed digital images

This document summarizes a research paper that proposes a practical self-recovery mechanism for JPEG compressed digital images. The mechanism extends a digital fountain code model to account for errors in watermark extraction and block classification. It guarantees high and stable reconstruction quality without introducing artifacts from errors. The mechanism also allows for efficient handling of high-resolution and color images. It introduces a hybrid approach to spreading reference information across the entire image, balancing tampering rates and computational complexity. This reduces watermark embedding times from minutes to seconds, even on mobile devices.
