ABSTRACT:
High security seal that can be reused an indefinite number of times because the authenticating part evolves in a chaotic manner each time the seal is opened and then put back into service. This seal is composed of at least two authenticators (1) and (2) at least one of which is movable with respect to the other into the open position. These two authenticators become fixed and stable in the closed position. In each new fixed position, the two authenticators cooperate to generate a new authenticating feature that is stored in a database in order to be compared during a check. This feature will be cancelled and replaced with another one when said seal is fraudulently or deliberately opened and thus will provide proof that it has been opened.
