A system and method are disclosed for encoding and decoding QR codes using multiple security levels through proprietary compression codebooks to increase information density and provide graduated data security. Input data is classified into public and multiple private security levels. Public data is encoded using a standard codebook while private data uses corresponding level-specific proprietary codebooks. The encoded data is combined into a single QR code with security level markers. Decoding extracts and processes each portion according to its security level using appropriate codebooks, enabling fine-grained access control while maintaining data compression benefits. The system supports complex security requirements while maximizing QR code capacity.

System and method for multi-level security in high-capacity QR codes

A system and method are disclosed for encoding and decoding QR codes using proprietary compression codebooks to increase information density and provide data security. Public data is encoded using a standard codebook while private data uses a proprietary codebook. The encoded data is combined into a single QR code. Decoding extracts the public and private portions and decompresses them using the appropriate codebooks.
