KeeeX is a spin-off from the LIS laboratory (Laboratoire d'Informatique et Systèmes/informatics and systems laboratory) and develops a universal and unbreakable digital authentication certificate. This technology delivers certified, time-stamped and geolocated data, and protects the integrity of goods, containers, documents, photos and videos as well as documents, photos and videos, thus countering any fraud attempt. The software is made tamper-proof by using the computer support of a Bitcoin blockchain.
