The invention relates to a method and device for verification of non-violation of the integrity of a system or the identity of an object. An authentication seal is used, comprising a physical authenticator with bubbles (3) produced by a chaotic process on the production thereof, a characteristic of which is to be always unique and non-reproducible. A representation of said identifier with bubbles is stored in the form of an image and/or digitally in a database local or remote to the address (17), for authentication of the assignment of the identifier in situ or on the object for protection. Said authenticator is provided with a physical connection (16) which permits connection to the site or object for identification. Any attack on the integrity of the seal, whether on the authenticator and/or the connection, irreversibly alters the total seal such as to render the same unreusable. Said authentication seal comprises a means for prevention of violation of the integrity of a site or the identity of an object and provides proof of an effective violation.

La présente invention concerne un procédé et un dispositif de vérification de non atteinte à l'intégrité d'un système ou à l'identité d'un objet. Il est utilisé un scellé d'authentification constitué d'un authentificateur physique à bulles (3) issues d'un chaos lors de sa fabrication et dont la particularité est d'être toujours unique et non reproductible. Une représentation sous forme d'image et/ou numérique de cet identificateur à bulles est stockée dans une base de données locale ou distante à l'adresse (17) afin d'authentifier l'affectation de l'identificateur au lieu ou à l'objet à protéger. Cet authentificateur est associé à un lien physique (16) permettant de le relier au lieu à protéger ou à l'objet à identifier. Toute atteinte à l'intégrité du scellé que ce soit à travers l'authentificateur et/ ou le lien, altère de façon irréversible la totalité du scellé afin de le rendre non réutilisable. Ce scellé d'authentification constitue un moyen de prévention de la non violation de l'intégrité d'un lieu ou de l'identité d'un objet et de preuve s'il y a eu violation effective.
