TL;DR

This paper presents a comprehensive survey of modern data hiding techniques, focusing on steganography as a method to conceal sensitive information within digital media for secure transmission over insecure networks. It evaluates various steganographic methods based on parameters like payload capacity, imperceptibility, and robustness, offering a comparative analysis to guide researchers in selecting optimal techniques for specific security and performance requirements.

ABSTRACT

With the explosive growth of internet and the fast communication techniques in recent years the security and the confidentiality of the sensitive data has become of prime and supreme importance and concern. To protect this data from unauthorized access and tampering various methods for data hiding like cryptography, hashing, authentication have been developed and are in practice today. In this paper we will be discussing one such data hiding technique called Steganography. Steganography is the process of concealing sensitive information in any media to transfer it securely over the underlying unreliable and unsecured communication network. Our paper presents a survey on various data hiding techniques in Steganography that are in practice today along with the comparative analysis of these techniques.

Motivation & Objective

• To provide a systematic review of contemporary data hiding techniques, particularly steganography, in response to growing concerns over data confidentiality in insecure networks.
• To analyze and compare existing steganographic methods based on key performance metrics such as payload capacity, distortion, and resistance to attacks.
• To identify strengths and limitations of different steganographic approaches to support informed selection for real-world applications.
• To serve as a reference for researchers and practitioners seeking to understand the current landscape of data hiding technologies.

Proposed method

• The study conducts a literature review of established steganographic techniques used in digital media such as images, audio, and video.
• It classifies data hiding methods based on their embedding domain (spatial, frequency, or transform domain) and embedding strategy (LSB, DCT, DWT, etc.).
• The paper evaluates techniques using standardized comparative criteria including payload capacity, visual quality (PSNR), and computational complexity.
• It synthesizes findings from multiple studies to present a side-by-side comparison of techniques in a tabular format for clarity.
• The analysis includes both reversible and non-reversible steganography methods, highlighting trade-offs between data capacity and distortion.
• The study draws conclusions based on aggregated performance data from cited works, focusing on practical applicability and security.

Experimental results

Research questions

• RQ1 What are the primary steganographic techniques used in modern data hiding, and how do they differ in implementation?
• RQ2 How do various steganographic methods compare in terms of payload capacity, image quality, and computational efficiency?
• RQ3 Which steganographic techniques offer the best balance between data security and imperceptibility in digital media?
• RQ4 What are the key limitations and vulnerabilities of existing data hiding methods?
• RQ5 How do different embedding domains (spatial, frequency, transform) influence the performance of steganographic systems?

Key findings

• Steganography techniques based on the Discrete Wavelet Transform (DWT) offer better image quality and higher payload capacity compared to traditional LSB-based methods.
• Methods using the Discrete Cosine Transform (DCT) in the frequency domain achieve moderate payload capacity with acceptable distortion, especially in JPEG-compressed images.
• LSB-based steganography remains widely used due to its simplicity and low computational cost, but it is vulnerable to statistical analysis and has limited robustness.
• Reversible steganography techniques allow for perfect recovery of the original cover image after data extraction, making them suitable for medical and legal applications.
• The comparative analysis reveals that no single method is optimal across all criteria, and trade-offs between payload, distortion, and security must be carefully evaluated.
• The study concludes that hybrid approaches combining multiple domains (e.g., DWT-DCT) may offer improved performance, though they increase implementation complexity.
