Combining 2D-Codes with an optical identification layer: Optropy is an encryption method that utilizes optical markers to securely embed data into two-dimensional code structures. It is based on a combination of symbolic, positional and reading diversity, making each optropic code visually unique. This optical encryption method is resistant to quantum attacks, operates offline, and remains compatible with existing standards.

What is Optropy?

Optropy (Optics + Entropy) is a groundbreaking encryption method that integrates optical markers into existing code structures, enhancing security without compromising readability. It leverages three key principles:

• Symbolic Diversity: Utilizing various graphic symbols for enhanced security
• Positioning Diversity: Dynamic marker placement for unique code structures
• Reading Diversity: Adaptive reading sequences per individual code

Key Features

• Offline Decryption: Access secured data without internet connectivity
• Non-Reversible: Encryption that cannot be back-engineered
• Interoperable: Fully compatible with GS1-Link and serialized production systems

What can be encrypted?

• Authentication Codes
• Access Credentials
• Device Passwords
• Digital Keys
• Tokens
• ...
