TLDR
A high capacity and high quality reversible watermarking method based on difference expansion that does not need to compress original values of the embedding area and explores the redundancy in the digital content to achieve reversibility.Abstract:
Reversible watermark has drawn lots of interest recently. Different from other types of digital watermarks, a reversible watermark has a special feature that the original digital content can be completely restored. In this paper we describe a high capacity and high quality reversible watermarking method based on difference expansion. A noticeable difference between our method and others is that we do not need to compress original values of the embedding area. We explore the redundancy in the digital content to achieve reversibility.read more

Reversible data hiding
TL;DR: A prediction-based conditional entropy coder which utilizes static portions of the host as side-information improves the compression efficiency, and thus the lossless data embedding capacity.

Method and apparatus for embedding authentication information within digital data
TL;DR: Arbitrary digital information is embedded within a stream of digital data, in a way that avoids detection by a casual observer and that allows a user to determine whether the digital data have been modified from their intended form.

Lossless data embedding--new paradigm in digital watermarking
TL;DR: This paper introduces a new paradigm for data embedding in images (lossless dataembedding) that has the property that the distortion due to embedding can be completely removed from the watermarked image after the embedded data has been extracted.
Patent
Lossless recovery of an original image containing embedded data
TL;DR: In this paper, a method and system embeds digital meta-data into an original image in such a way that the meta data can be completely removed at a later time to allow loss less recovery of the original image.

The emerging JBIG2 standard
TL;DR: The Joint Bi-Level Image Experts Group (JBIG), an international study group affiliated with ISO/IEC and ITU-T, is in the process of drafting a new standard for lossy and lossless compression of bilevel images, informally referred to as JBIG2, which will support model-based coding for text and halftones to permit compression ratios up to three times those of existing standards for Lossless compression.
