Three-Dimensional Mesh Steganography and Steganalysis: A Review

Area of Science:

• Computer Science
• Digital Forensics
• Information Security

Background:

• Three-dimensional (3-D) meshes are crucial for representing virtual surfaces and volumes across various industries.
• The practical significance of 3-D meshes has grown, particularly in applications involving data hiding (steganography) and detection (steganalysis).

Purpose of the Study:

• To provide a comprehensive and systematic survey of the existing literature on 3-D mesh steganography and steganalysis.
• To propose a novel taxonomy for classifying steganographic algorithms applied to 3-D meshes.
• To categorize steganalysis algorithms for 3-D meshes and discuss their evolution.

Main Methods:

• A systematic literature review was conducted on 3-D mesh steganography and steganalysis.
• A new taxonomy for steganographic algorithms was proposed, categorizing them into four domains: two-state, LSB, permutation, and transform.
• Steganalysis algorithms were classified into two main categories: universal and specific.

Main Results:

• The survey presents a structured overview of technical developments and current capabilities in 3-D mesh steganography.
• A detailed discussion of universal and specific steganalysis techniques for 3-D meshes is provided.
• The study identifies and discusses emerging trends and challenges in the field.

Conclusions:

• The proposed taxonomy offers a refined framework for understanding 3-D mesh steganography.
• The survey highlights the need for continued research to enhance the performance and robustness of 3-D mesh steganography and steganalysis techniques.
• Future research should focus on addressing identified challenges to advance the state-of-the-art in 3-D mesh data security.
