Feature Bagging for Steganographer Identification
Hanzhou Wu
Traditional steganalysis algorithms focus on detecting the existence of steganography in a single object. In practice, one may face a complex scenario where one or some of multiple…
Reversible Video Data Hiding Using Zero QDCT Coefficient-Pairs
Yi Chen, Hongxia Wang, Hanzhou Wu +1
H.264/Advanced Video Coding (AVC) is one of the most commonly used video compression standard currently. In this paper, we propose a Reversible Data Hiding (RDH) method based on H.…
The Cut and Dominating Set Problem in A Steganographer Network
Hanzhou Wu, Wei Wang, Jing Dong +2
A steganographer network corresponds to a graphic structure that the involved vertices (or called nodes) denote social entities such as the data encoders and data decoders, and the…
Reversible Embedding to Covers Full of Boundaries
Hanzhou Wu, Wei Wang, Jing Dong +2
In reversible data embedding, to avoid overflow and underflow problem, before data embedding, boundary pixels are recorded as side information, which may be losslessly compressed.…
Ensemble Reversible Data Hiding
Hanzhou Wu, Wei Wang, Jing Dong +1
The conventional reversible data hiding (RDH) algorithms often consider the host as a whole to embed a secret payload. In order to achieve satisfactory rate-distortion performance,…
