Commutative Encryption and Data Hiding in HEVC Video Compression

Commutative reversible data hiding and encryption

This work proposes a novel scheme of commutative reversible data hiding and encryption. In encryption part, the gray values of two neighboring pixels are masked by same pseudo-random bits. In data-hiding part, the additional data are embedded into various bit planes with a reversible manner, and a parameter optimization method based on a capacity–distortion criterion is used to ensure a good pe...

Video-in-Video Data Hiding

This paper investigates the implementation of a vector-embedding scheme in video. The embedding procedure is conducted using an algorithm that is robust to standard video coding techniques such as MPEGI and II. The vector-based algorithm, using lattice codes and texture mapping for improved performance, allows large amounts of data to be stored into each frame of the video sequence. Furthermore...

A Large-capacity Information Hiding Method for HEVC Video

A large-capacity information hiding algorithm for HEVC is proposed. We modify the intra prediction modes in 4x4 luminance blocks to embed secret information. According to the probability distribution of the statistical optimal prediction mode and suboptimal prediction mode, we are establishing a mapping relationship between prediction modes and secret information. Modifying the intra prediction...

Data Hiding in Video

We propose a video data embedding scheme in which the embedded signature data is reconstructed without knowing the original host video. The proposed method enables high rate of data embedding and is robust to motion compensated coding, such as MPEG-2. Embedding is based on texture masking and utilizes a multi-dimensional lattice structure for encoding signature information. Signature data is em...
