Technology behind the fortress
Eight layers of defense working in concert to make image theft economically irrational at internet scale.
Canvas-Based Rendering
Images are never served as standard <img> tags. Instead, encrypted pixel data is streamed and painted directly onto an HTML5 Canvas element, eliminating downloadable URLs entirely.
- No image URL to copy or scrape
- Right-click save completely disabled
- Tainted canvas prevents programmatic extraction
- Hardware-accelerated rendering
Domain Locking
Cryptographically bind your assets to specific authorized domains. If embed code is copied to an unauthorized site, the image refuses to decrypt and shows a protection placeholder.
- Referer & Origin header validation
- Wildcard subdomain support
- Real-time domain verification
- Instant unauthorized access alerts
Edge Encryption (AES-256)
Every image is encrypted with AES-256-CBC before storage. Decryption happens in the browser via Web Workers, ensuring the unencrypted image never touches disk or network cache.
- Military-grade AES-256-CBC encryption
- Daily key rotation
- Web Worker decryption (off main thread)
- Zero-knowledge architecture
