Research
Achievements: 1. In the area of Lossless Data Hiding: A novel semi-fragile lossless digital watermarking scheme based on integer
wavelet transform (IWT) has been developed. This method takes special measures to prevent
overflow/underflow (one of critical issue for lossless watermarking) and hence does not suffer from annoying saltand-pepper
noise, compared with the only existing lossless data hiding reported in the literature. It becomes the
best robust invertible watermarking scheme, i.e., the state-of-the-art in this subject. This work won the grant from
DDET (Digital Data Hiding Technology), Air Force Research Laboratory, Rome, NY, in 2003. This technology
has been adopted in a unified authentication framework, which has been included in Security Part of
JPGEG2000, CD (Committee Document) 1.0 in April 2004. A US provisional patent has been filed in December
2003. An IEEE journal paper was submitted in September 2004.
2. In the area of Multimedia Content Authentication: A digital image authentication framework has been proposed
to protect the very content of image instead the digital representation. In this framework the features of a target
image are first extracted and signed using the Digital Signature Algorithm (DSA). The authentication information
is generated from the signature and the features are then inserted into the target image using the lossless data
hiding algorithm described previously. This work is collaborated with IBM T.J Watson Research Center in
Yorktown Height, NY. An IEEE journal paper is in preparation.

3. In the area of Text Document Data Hiding: A data hiding scheme aiming at formatted text documents has been
invented. It is a blind algorithm, meaning the original document is not needed for hidden data extraction. The
performance on robustness is superior over all existing technologies. The stego-document can be subjected to
printing, copying and scanning. Specifically, the hidden data can still be correctly extracted after the document
has experienced one printing, followed by 10 times of copying, and one scanning. This is the best blind robust
document data hiding algorithm compared with all the existing algorithms. This invention has been disclosed to
NJIT in July 2004. A US provisional patent has been filed in December 2004. A research proposal has been
submitted to DDET, Air Force Research Laboratory in May 2004. This technology opens possibility to Digital
Notarization.
4. In the area of Steganalysis: Steganalysis is to detect the hidden message, and is urgently requested by military
and cyber security. So far, the area is very young. The most hard stegnography methods to be detected are the
so-called spread-spectrum based algorithms. There exists no previous steganalysis methods which can handle
this tough case. As a major team member in the research group, I have made significant contribution to this area.
Our recent investigation indicates that our newly developed framework can detect stego-media created by using
the typical spread-spectrum scheme with a successful rate close to 80%. This work in this regard leads to a
proposal submitted to DDET Air Force Research Laboratory in September. Patents and IEEE journal papers are
expected.
