🔐 How Steganography Works
LSB (Least Significant Bit)
The most common method replaces the least significant bits of pixel color values with message bits. This creates minimal visual changes while hiding data.
- 1-bit LSB: Most secure, lowest capacity
- 2-bit LSB: Balanced security and capacity
- 3-bit LSB: Higher capacity, more detectable
Encryption Layer
Messages are encrypted using AES-256 before hiding, providing double protection even if the steganography is detected.
- AES-256-GCM encryption
- Password-based key derivation
- Authentication and integrity
Detection Resistance
Our implementation uses advanced techniques to resist statistical detection methods commonly used in steganalysis.
- Pseudo-random distribution
- Minimal statistical artifacts
- Adaptive payload placement
⚠️ Security Best Practices
- Use strong passwords: Always encrypt messages with a strong, unique password
- Choose PNG format: PNG provides lossless compression, preserving hidden data
- Avoid compression: JPEG compression can destroy hidden messages
- Test thoroughly: Always verify message recovery before relying on it
- Use secure channels: Combine with other security measures for sensitive data
