**1 2D-SSA (Two-Dimensional Singular Value Decomposition) Steganography Principles and Process** **Principle** 2D-SSA is based on the singular value decomposition (SVD) of matrices, embedding secret information by modifying the singular values of the carrier image. The singular values reflect the energy distribution of the image and are robust to small modifications. **Process** The carrier image is divided into multiple submatrices, and SVD decomposition is performed on each submatrix: $A = U \Sigma V^T$ Select the singular values in the middle frequency band for slight modification to embed information, usually using quantization or replacement strategies. The image blocks are reconstructed through inverse SVD, and all blocks are merged to obtain the stego image. — **2 WMF (Weighted Matrix Filtering) Steganography Principles and Process** **Principle** WMF utilizes the weighted statistical characteristics of local regions of the image, embedding information by adjusting pixel weights. Its core is to hide data in the spatial domain through filtering operations, maintaining visual invisibility. **Process** The carrier image is processed in blocks, and the weighted matrix for each block is calculated: $W_{i,j} = \frac{1}{1 + \alpha \cdot |I_{i,j} – \mu|}$ where $bc$ is the block mean, and $b1$ is the adjustment factor. The weight distribution is adjusted according to the secret information bits, and pixel values are reconstructed through inverse filtering. All blocks are merged and boundary transitions are optimized to generate the stego image. — **3 Key Differences** – **Embedding Domain**: 2D-SSA operates in the transform domain (singular values), while WMF operates directly in the spatial domain (pixel weights). – **Robustness**: 2D-SSA is more robust to compression/noise, while WMF is more sensitive to geometric attacks. – **Capacity**: WMF typically supports a higher embedding rate but may introduce more noticeable distortion. Code Example (Core Segment for 2D-SSA Embedding): “`python
def embed_svd(block, secret_bit):
U, s, Vh = np.linalg.svd(block)
# Modify the k-th singular value
s[k] = quantize(s[k], secret_bit)
return U @ np.diag(s) @ Vh
“`
