| 20110018253 | SECURITY ELEMENT - A security element for the identification and authentication of objects is disclosed. The element is connected by a self-adhesive label to an object. It has features that effectively prevent non-destructive detachment of the security element from an object. The security element has an optical code for identification. Furthermore, it is provided with random production-governed features by means of which authentication is made possible: upon irradiation with electromagnetic radiation, a scattering region of the security element brings about a characteristic scattering signal. The method of using the security element is disclosed for the identification and authentication of objects and also for protection against forgeries, and a method for the identification and authentication of objects on the basis of the security element. | 01-27-2011 |
| 20110031735 | SECURITY ELEMENT - The invention relates to optical security elements, their use for identifying and authenticating objects and processes and devices for identifying and authenticating objects using the optical security elements. | 02-10-2011 |
| 20110049235 | Method and Device for Identifying and Authenticating Objects - The invention relates to a process for identifying and authenticating an object. The object includes an identifier which has a code region and a scattering region and is irradiated with electromagnetic radiation for identifying and/or authenticating the object, in such a manner that the electromagnetic radiation reflected by the code region is used for identifying the object and the electromagnetic radiation reflected by the scattering region is used for authenticating the object. In addition, the invention relates to a device for the parallel identification and authentication of an object | 03-03-2011 |
| 20110176137 | Optical Sensor - The invention relates to an optical sensor for detecting characteristic reflection patterns caused by randomly distributed and/or oriented microreflectors. The invention furthermore relates to the method od using a sensor according to the invention for identifying and/or authenticating objects. | 07-21-2011 |
