QRIDS (Quick Response Identification by Structure) is a project aimed at developing a technology for identifying and authenticating physical parts based on their material structure. The principle involves scanning the surface of an object (e.g. a pellet or material) with an optical device called QBOX, then analysing the micro-structural characteristics of the image to create a unique fingerprint of the material.

The system works in several steps:

• Acquisition of an image of the part
• Transfer to an analysis system
• Extraction of a digital signature using algorithms (e.g. DFT or PolarSign)
• Comparison with a database to identify or authenticate the object

The goal is to provide a traceability and anti-counterfeiting solution, usable in fields such as industry or luxury goods, potentially with a mobile application connected to an authentication backend.

The project includes the development of capture hardware (QBOX), identification algorithms, software infrastructure (API, database, containers) and demonstrators for industrial partners.
