Digital Watermarking for Creators
Digital watermarking embeds ownership information directly into your content in a way that survives copying, compression, and reposting—making it possible to prove authorship even when your work appears on other platforms.
Digital watermarking is the practice of embedding hidden information into digital content (images, videos, audio, documents) that can later be extracted to prove ownership. Stelais uses advanced steganographic techniques to create invisible watermarks that persist through common transformations like compression, cropping, and format conversion.
Visible vs. Invisible Watermarking
Visible Watermarks
- Obvious overlay on content (logos, text)
- Deters casual copying
- Easy to remove with editing tools
- Degrades visual quality
Invisible Watermarks (Stelais)
- Hidden in pixel data or file structure
- Survives compression and reposting
- Cannot be seen or easily removed
- Maintains full visual quality
How Stelais Watermarking Works
Stelais uses multiple layers of invisible watermarking to ensure your ownership information persists through various transformations:
Frequency Domain Embedding
Watermarks are embedded in the frequency domain of your content, making them resistant to common image processing operations like resizing and compression.
Redundant Encoding
Ownership data is encoded multiple times across different regions of your content, ensuring it can be recovered even if portions are cropped or modified.
Cryptographic Binding
Watermarks are cryptographically linked to your identity and the blockchain proof, preventing forgery or transfer.
Adaptive Strength
Watermark intensity automatically adjusts based on content type to maximize durability while minimizing perceptibility.
Watermarking + Hashing: Complete Protection
While watermarking proves ownership of modified copies, cryptographic hashing proves the exact original state of your work. Stelais combines both approaches:
Cryptographic Hash
A unique fingerprint of your exact content at registration time. Any modification—even a single pixel—produces a completely different hash, proving tampering.
Invisible Watermark
Embedded ownership data that persists through modifications. Even if your content is compressed, cropped, or converted, the watermark can be extracted to prove you're the original creator.
Together, hashing and watermarking provide complete coverage: the hash proves the original, and the watermark traces copies back to you.
