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 () 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 (), for authentication of the assignment of the identifier in situ or on the object for protection. Said authenticator is provided with a physical connection () 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 un-reusable. 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.

The present invention relates to a method for certifying and subsequently authenticating original physical or digital documents. The concept of the evidence lies in the dual nature of a physical information item and a digital information item, one being the reference for the other that cannot lie amended at the risk of the evidence being lost. For a physical original document associated with a bubble seal there is a corresponding time-and-date-stamped, proprietary paperless reference counterpart. For a time-and-date-stamped, proprietary digital original document there is a corresponding reference counterpart in the form of a bubble seal.

The invention concerns a process and the associated universal device for supporting a part () of random and/or possibly complex shape in relation to a rigid base () while establishing a work reference. It consists of inserting between the part to be held and the rigid base (), at least one deformable airtight enclosure () of constant volume full of incompressible particles (). Then vacuum is applied inside the deformable enclosure () of constant volume using a vacuum source () which can be connected to the deformable enclosure (). Thus the particles () amalgamate to constitute a solid block which at least partially rests on the rigid base () and holds the part () matching its shapes.

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 () and () 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.

A method for making transactions secure based upon a card-type medium () comprising a number () and a remote database () connected to a telecommunications network. A unique and non-reproducible identifier () in the form of a bubble code is physically affixed to the card () comprising a number () contained either on a magnetic strip, of a bar code, or in an electronic label. One representation of this identifier () and or () is stored in the remote database () at the same number () as that present on the medium. This identifier () constitutes an unforgeable link between the magnetic strip () and the database (). When a call is made to the remote database by means of the number recorded on the card, a link authentication is performed by comparing the representation of the identifier stored in said database and the actual identifier.

Identification and authentication procedure without specific reader of a three-dimensional identifier (), (), (), () attached to an object or living being by using sensory capabilities of the human being notably its stereoscopic vision capabilities (A) and its tactile sense (A') permitting the appreciation of the particularity of the identifier which renders the latter difficult or impossible to reproduce which are, for example, heterogeneities mixed in a transparent material or surface ridges and/or cavities. The identification or reading is then carried by the visual comparison (B) of a two-dimensional representation image () of the identifier () () () () stored in a database () accessible by a network () and the identifier himself.

Method for identification and authenticating without specific reader an identifier

This invention involves a reading process for three-dimensional means of identification () that are unique and non-reproducible (), containing a mixture of at least two materials (and) that are distinguishable from one another (and), remarkable in that it consists of one part to recognize the internal heterogeneous structure of the means of identification () in two dimensions, and another part to verify and prove its third dimension to render falsification impossible. This characteristic reduces the amount of storage memory as well as the length of time necessary to perform the operations of reading, acquisition, and comparison usually conducted in such processes. The invention also involves a device that implements said process as well as a means of identification adapted to said process.

A method and apparatus for carrying out the deposition of a paste like and/or viscous material, such as solder paste, on a substrate through the apertures or openings of a stencil are provided for use, for example, in screen printing in the mounting of components on a printed circuit board. A hollow receptacle for the material is provided with a lower aperture which is orientated towards the stencil. The lower aperture of the receptacle is delimited defined such that its length is adjusted to the dimensions of the substrate and that its width is a function of the speed of execution of the screen printing. This delimitation is implemented by sealing members preferably comprising two wipers on respective sides of the aperture, transverse with respect to the direction of displacement of the receptacle, orientated one towards the other and inclined with respect to the horizontal between the wipers at an angle of between 120&deg; and 180&deg;. The wipers are transversal and intersecting with the section of the receptacle. A pressure is exerted upon the viscous material in the receptacle. This pressure pushes the material towards the stencil between the wipers to distribute it over the stencil, and pushes the product upon the wipers, applying pressure to the wipers in order to push the wipers onto the stencil. The receptacle is displaced across the stencil at the same time that the pressure is exerted on the material.
