Field drug-testing kits currently in use rely on subjective visual interpretation of chemical color-change reactions. This makes results inconsistent across officers under varying lighting conditions, leaves no verifiable evidentiary record, and prevents field test outcomes from being admitted as rigorous documentary evidence in legal proceedings.
Build a mobile software application that works alongside existing colorimetric field-test kits to standardize color analysis, automate drug detection, and generate cryptographically sealed digital evidence dossiers.
Smartphone cameras exhibit diverse sensor color sensitivities, white-balance variations, and lens distortions; field lighting varies from direct noon sunlight to flickering sodium streetlights; evidence chains of custody must withstand strict judicial scrutiny.
An offline-first mobile application that uses a physical color-reference calibration card to normalize camera images, automatically detects and measures colorimetric reaction kinetics against standardized chemical libraries, and generates a tamper-evident, GPS/time-stamped PDF evidence dossier signed with device credentials.
