Fraud Or Tamper Detecting Patents (Class 428/916)
-
Patent number: 4945708Abstract: The invention provides a package and associated method for packaging of products which enhances the resistance to tampering with or adulteration of the product, and which also permits a readily visible indication that any such tampering or adulteration has occurred. The invention in one form provides an inner container which is in turn provided with an outer protective layer of epoxide resin. The outer layer is cured and it becomes extremely brittle such that any physical penetration of the outer layer will cause the entire outer layer to shatter. Such shattering will provide a clear indication that penetration of the protective layer has occurred. Also there may be provided an associated dye which will exhibit a color change when the outer protective layer is shattered. A warning message may be provided on said packaging underlying the outer layer.Type: GrantFiled: July 31, 1989Date of Patent: August 7, 1990Assignee: TSL IncorporatedInventor: Yoram Curiel

Patent number: 4940690Abstract: The present invention provides a laminate construction including a backing sheet, which may be in the form of a continuous web, and a face sheet covering at least a portion of the backing sheet. A releasable adhesive secures a first or lower surface of the face sheet to a first or upper surface of the backing sheet such that the face sheet and backing sheet are readily separable. The releasable adhesive contains therein a first composition which, when subjected to an imaging force, forms a latent image on both of the first surfaces of the face and backing sheets. This latent image may be developed at a later time by contacting the image with a second composition which, when exposed to the first composition, forms a visible image. In the laminate, the face sheet may be imprinted with legible and/or covert information. The covert information may be duplicated on the underside of the face sheet or on one or more intermediate sheets as well as a backing sheet.Type: GrantFiled: July 27, 1988Date of Patent: July 10, 1990Assignee: The Standard Register CompanyInventor: Hugh B.

Patent number: 4894110Abstract: Information is provided in a multilayer identification card by means of a laser beam. This information is recorded by irreversibly changing (blackening) transparent synthetic material. Synthetic materials which blacked at different intensity values are used for the individual card layers. By controlling the laser beam intensity, information can thus be recorded only in one layer or else simultaneously in several layers. If the layer arrangement, layer materials and recording parameters (intensity, writing width, etc.) are selected appropriately, images can be produced which change their appearance when the viewing angle is changed. The various visual effects which can thereby be obtained serve to distinguish the authenticity of the identification card.Type: GrantFiled: June 29, 1988Date of Patent: January 16, 1990Assignee: GAO Gesellschaft fur Automation und Organisation mbHInventors: Joseph Lass, Hansjurgen Merkle, Wolfgang Becker, Werner Herget, Erwin Lob

Patent number: 4687526Abstract: A high-security identification card is produced in a system in which a photograph from a video camera is converted to digital data and reproduced with high-fidelity on a video display screen. Other images, such as signatures and fingerprints, can be treated in a similar manner using either a video camera or a CCD (charge-coupled device). After processing, the video information is displayed on the screen where it is combined with variable data typed in from a keyboard. The digital data from the terminal is fed into a laser printer that prints the portrait and any desired alphanumeric information on a paper sheet. The paper is then laminated, under heat and pressure, between two sheets of transparent thermoplastic material, at a temperature and pressure sufficient to cause the plastic material to penetrate the interstices between the fibers of the paper card and form a unitary structure that cannot be delaminated without destruction of the identifying data.Type: GrantFiled: January 8, 1986Date of Patent: August 18, 1987Assignee: Identification Systems Company L.P.Inventor: Ronald A.

Patent number: 4631223Abstract: An embossing foil includes a layer which can be written upon, together with a magnetic layer for data storage purposes. Between the magnetic layer and the writing layer, the foil has a layer with a barrier effect to prevent the writing layer from being attacked by solvent contained in the magnetic layer. The foil may further comprise between the magnetic and writing layers, a structure producing an optical diffraction effect such as a hologram, with the writing surface and said structure being so arranged that nonetheless said structure can still be read, including by machine.Type: GrantFiled: May 16, 1985Date of Patent: December 23, 1986Assignee: Messrs.

Patent number: 4629647Abstract: An embossing foil includes a signing layer which can be written upon, in conjunction with a layer having a structure giving an optical diffraction effect such as a hologram. The signing layer may be clear in the region over the diffraction structure or alternatively the signing layer, over the diffraction structure, may be of a patterned or grid configuration defining openings through which the structure therebeneath can be viewed. The foil may also include a magnetic layer for the storage of variable data which can be readily accessed.Type: GrantFiled: May 16, 1985Date of Patent: December 16, 1986Assignee: Leonhard Kurz GmbH & Co.Inventor: Helfried Sander

Patent number: 4627642Abstract: The present invention relates to a method for deterring fraud with documents having monetary value such as a PVC substrate having a signature location on the substrate. In the method, a supporting ink layer 2 including a pigment and containing a product that assures it a certain porosity with respect to the substrate is deposited on the signature location; then a transparent, porous varnish layer 3 including a dissolved powder enabling a fluorescence of the desired color to be obtained under ultraviolet light is deposited on certain zones of the first ink layer 2; next a filigree pattern is printed in zones of either the first ink layer 2 or the varnish layer 3, using a silkscreening process and a second pigmented vinyl ink 4. The signature or identifying mark of the owner of the document is executed using a felt-tip pen having an indelible ink, of the type which is indelible to a product such as that sold under the mark "CORRECTOR".Type: GrantFiled: September 5, 1985Date of Patent: December 9, 1986Assignee: Sotimag (SARL)Inventors: Georges Peronneau, Bernard Chalus
