TAMPER-PROOF AND REUSABLE HIGH SECURITY SEAL

摘要

The seal has a pair of authenticators (1, 2) moved with respect to each other in an open position and fixed in a closed position, where the authenticators provide unique and non-reproducible authenticating features (15-17) e.g. bubbles. The authenticators act separately and in an instable manner when the seal is in non-blocked and open position and act jointly and in a stable manner when the seal is in blocked and closed position for creating a new code or signature whose representation is stored in a data base. The authenticators are evolved in a chaotic manner each time the seal is opened.
