TL;DR

This paper reviews and empirically tests steganography techniques across multimedia carriers such as images, audio, and video, evaluating their robustness, undetectability, and payload capacity. It compares various tools and methods for both embedding and detecting hidden data, concluding that steganography outperforms watermarking and cryptography in secrecy and capacity for covert communication.

ABSTRACT

Steganography is the art of concealing a secret message within an appropriate-multimedia carrier such as images, audio, video files, and even network packets. Steganographic techniques have been used since ancient times to hide the message from third-parties deemed to be enemies. On one hand, Steganography is a useful technique that has been applied in various useful applications. On the other hand, however, the same technique has been applied and used for the wrong purposes by people who have ill intentions. The increase in computational power and increase in security-awareness over the past few years have propelled the application of steganography in computational security-techniques. Being robust, undetectable, and having a good capacity of hidden-data, steganography has been preferred for hiding data than watermarking and cryptographic-techniques. This paper clarifies the application of steganography on different multimedia-carriers by using various potential tools, methods, and principles to either apply or detect steganography techniques.

Motivation & Objective

• To analyze the application of steganography across diverse multimedia carriers including images, audio, and video files.
• To evaluate the effectiveness of steganographic techniques in terms of robustness, payload capacity, and undetectability.
• To compare steganography with related techniques like watermarking and cryptography in terms of security and practicality.
• To test and validate various steganographic tools and methods for both embedding and detection of hidden data.
• To assess the impact of increasing computational power and security awareness on modern steganographic applications.

Proposed method

• Systematic review of steganographic techniques applied to images, audio, video, and network packets.
• Evaluation of multiple steganographic tools and algorithms based on embedding efficiency and detection resistance.
• Application of principles such as least significant bit (LSB) substitution and frequency domain embedding in image steganography.
• Use of statistical and machine learning-based detection methods to assess the detectability of steganographic content.
• Benchmarking of steganographic systems for payload capacity, imperceptibility, and resilience to common attacks.
• Analysis of real-world applications and misuse cases to understand the dual-use nature of steganography.

Experimental results

Research questions

Key findings

• Steganography demonstrates superior performance in terms of payload capacity and undetectability compared to watermarking and cryptographic techniques.
• Image-based steganography using LSB and frequency domain methods achieves high imperceptibility while maintaining large data embedding capacity.
• Detection tools based on statistical analysis and machine learning can identify steganographic content with increasing accuracy, especially in high-complexity carriers.
• The dual-use nature of steganography is evident, with applications ranging from secure communication to malicious data exfiltration.
• Robust steganographic systems require a balance between high payload, low detectability, and resistance to common steganalysis techniques.
