LSB-based pre-embedding video steganography with rotating & shifting poly-pattern block matrix.

Area of Science:

• Computer Science
• Information Security
• Digital Forensics

Background:

• Video steganography offers greater data-hiding capacity than other methods.
• Spatial domain video steganography faces robustness challenges against attacks.
• Achieving a balance between robustness, imperceptibility, and payload is crucial.

Purpose of the Study:

• To develop a robust and imperceptible video steganography technique.
• To enhance security against visual, statistical, and transformation-based steganalysis.
• To improve upon existing Least Significant Bit (LSB) based methods.

Main Methods:

• Proposed an LSB-based video steganography application utilizing a poly-pattern key block matrix (KBM).
• Implemented dynamic KBM security through sub-pattern shifting, rotation, and logical operations (XOR, AND).
• Employed a variable KBM structure and logical operators for distinct secret data embedding.

Main Results:

• Achieved excellent imperceptibility metrics: MSE (0.00066), SSIM (0.99999), PSNR (80.01458 dB) for 42.8 Kb.
• Demonstrated superior performance compared to classic LSB and other LSB-based video steganography approaches.
• Showcased increased resistance to statistical and transformation attacks due to variable KBM and logical operations.

Conclusions:

• The proposed method offers high imperceptibility and payload capacity.
• Enhanced security features provide significant resistance against various steganalysis attacks.
• The technique presents a robust and secure solution for video steganography.
