Progressive Generative Steganography (PGS) Workflow
The proposed PGS network architecture is composed of two main stages: Information Hiding based on progressive image generation and Information Extraction. The Information Hiding stage involves a Transformer for secret message-to-noise map conversion, and then Generative Adversarial Networks (SINGAN) for progressive image generation guided by these noise maps. The Information Extraction stage reverses this process, using Extractors to recover noise maps and reconstruct the secret message. A key component is the robust Secret-to-Noise (S2N) transformation, and the Dense Secret-Feature Connection (DSFC) strategy which improves image quality and extraction accuracy by fusing secret bits with attention-weighted feature maps.

S2N Transformation & DSFC Strategy
The Secret-to-Noise (S2N) transformation method is crucial for encoding secret messages into noise maps robustly, ensuring high extraction accuracy even under various image attacks. It involves S2N mapping, which converts secret bits into decimal values and then into noise values within specific subranges, and S2N adjusting, which modifies noise values to align with up-sampled image pixel values for better image quality and extraction. The Dense Secret-Feature Connection (DSFC) strategy enhances message extraction and stego-image generation by fusing secret bits with attention-weighted feature maps from the Generators. This dynamic fusion, guided by channel attention blocks, allows for more accurate weight calculation and a stronger association between secret messages and image features.

PGS vs. State-of-the-Art Steganography
The PGS method significantly outperforms existing steganographic approaches in both hiding capacity and extraction accuracy, especially at higher payloads. Traditional methods like S-UNIWARD and Deep-Stego show decreasing accuracy as hiding load increases due to cover image modification and limited hiding spaces. Generative methods like SWE, GSN, IDEAS, and Li et al. also generally have lower extraction accuracy than PGS, as their neural networks are not fully reversible. PGS achieves a high extraction accuracy rate (Racc ≈ 0.97) even when the hiding payload ranges from 2 bpp to 3 bpp.

Enterprise Applications of PGS
The high hiding capacity and robustness of PGS make it suitable for various enterprise applications requiring secure covert communication. This includes secure data transfer in sensitive sectors, intellectual property protection, and discreet message exchange in scenarios where traditional encryption might raise suspicion. Its ability to generate stego-images from scratch, without modifying existing cover images, ensures high imperceptibility and anti-detectability, crucial for maintaining operational stealth in critical business communications. The approach is particularly beneficial for high-volume, secure data transmission needs within complex network infrastructures.
Secure Internal Communications
A financial institution could leverage PGS to embed sensitive internal memos or compliance reports directly into generated visual assets (e.g., dashboard backgrounds, company logos), ensuring that critical information is exchanged without raising red flags from external monitoring systems. The high capacity allows for comprehensive documents, and anti-detectability ensures complete stealth.
Value: Enhanced data security and operational stealth for sensitive information exchange.
