Authentication is key to all of our solutions by proving that a SigNature DNA mark is present on or in an item. Our patented and proprietary authentication methodologies allow for SigNature DNA authentication marks to be detected and verified. Test results provide customers with a Certificate of DNA analysis (CODA), which can be used as evidence in courts around the world.

SigNify authentication services consist of 3 options:

  • Full forensic authentication at our laboratory in Stony Brook, NY
  • Field-level mobile units for point-of-activity authentication
  • On-site authentication at a customer’s QC/QA certified lab
