Poly-chromatic Poly-digital Code for Secure Passive Scanning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional barcodes and QR codes are limited by their binary nature, requiring controlled active illumination for scanning and being susceptible to replication and compromise due to distinct positioning symbols, which restricts the types of readers that can be used and compromises code integrity.
Innovation Solution
The development of two-dimensional, poly-chromatic, poly-digital codes, known as polycodes, which utilize a matrix of colored pixels to represent encoded integers, incorporating orientation and validation cells that are visually indistinguishable from data cells, allowing for passive scanning and enhanced security through poly-digital encoding and complex color combinations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If binary monochromatic codes (QR codes, barcodes) are used, then reader compatibility with simple devices is improved, but code sophistication and security are limited
Solution Approach 1:
The patent changes the fundamental parameters of the code from binary monochromatic to poly-chromatic poly-digital. Each cell can display multiple colors and digital values (0-7 in base-8), dramatically increasing the information density and security while maintaining compatibility with standard imaging devices for scanning.
2Measurement precision
If controlled active illumination with laser is used for scanning, then scanning precision is improved, but device complexity and cost increase
Solution Approach 1:
The code structure itself provides the scanning information through its poly-chromatic design. The orientation and validation cells are visually indistinguishable from data cells, allowing any standard imaging device to read the code without requiring specialized active illumination or complex scanning mechanisms.
3Ease of operation
If positioning symbols are made visually distinct from data cells, then code orientation identification is improved, but code integrity and security are compromised
Solution Approach 1:
The patent introduces asymmetry through the validation cell pattern, which provides orientation information while maintaining visual consistency with data cells. The asymmetric arrangement of chromatic information within the grid enables orientation identification without creating visually distinct markers that could be easily replicated or compromised.

AI summary
A system and method employing two-dimensional, cryptographic, poly-chromatic, poly-digital codes (“polycodes”) that may be employed in connection with various digital transactions and communications applications are disclosed. In some implementations, a polycode may generally comprise a plurality of discrete code cells arranged in a two-dimensional matrix, each of the plurality of code cells displaying a combination of zero or more pure chromatic inputs representing an encoded integer; the number of possible combinations of pure chromatic inputs is equal to the number of possible integer values such that a discrete combination of pure chromatic inputs is unique to a discrete integer that is used in the polycode.
