# Multilingual LSB Stego Dataset

## Dataset Summary
This dataset contains **432,000 RGB images (~345 GB)** generated to study the detectability of **Least Significant Bit (LSB)** steganography under controlled, reproducible settings. It enables systematic analysis across **multiple resolutions, bit-depths, payload ratios, embedding policies, and languages**, and includes per-file metadata for deterministic message recovery.

- **Total size:** ~345 GB
- **Images:** 432,000
- **Languages (payload):** EN, DE, ES, FR, IT, TR
- **Resolutions:** 128×128, 256×256, 512×512, 1024×1024
- **Bits per byte (LSB depth):** 1, 2, 4
- **Payload ratios (of capacity):** 0.25, 0.50, ~1.00
- **Embedding policies:** sequential, random (seeded)
- **Metadata:** JSON for each stego image (original filename, message length, bpp, policy, seed, status)
- **Deterministic header:** `flag | msg_len(32) | num_bits_code(2) | [seed(32)]` for exact extraction

Each leaf folder contains:
- **Stego images** (as PNG)
- **JSON metadata** for each stego image (embedding parameters & verification)
- (Optionally) **histogram PNG/JSON** if generated

## Usage
```python
from datasets import load_dataset

# Load entire repository
ds = load_dataset("emirozturk/LSBStegoDataset")

# Load a specific subset/folder (example: 256x256 Turkish)
ds_tr256 = load_dataset(
    "emirozturk/LSBStegoDataset",
    data_files="256x256_tr/*"
)
```

## Typical Research Tasks
- Detectability vs. payload × bpp × policy × language × resolution
- Cross-lingual generalization of steganalysis models
- Feature-level analyses of language-induced bit statistics
