Abstract: The invention relates to a security device and an authentication method, in which a security element (1) is provided. The security element comprises a support material (6), in which a three-dimensional pattern with structures (4) such as cracks, grooves, flaking, pits, scales, elevations, and/or shrinkages are embedded as static or dynamic security features.

Abstract: The invention relates to an authentication system, comprising a security element (1) having a changing or changeable surface (6), structure, volume, composition, or sequence of characters, an assignment means, which assigns the security element (1) to a person, an object, a medium, or a group of these, a local or central memory device for storing security feature, an interrogator for retrieving a current visual appearance of the security feature, a data synchronization means for comparing the retrieved visual appearance with the visual appearance of the security element (1) stored in the local or central memory device, wherein an inherent or external trigger means is present, which effects a change at least in some areas of a surface (6), structure or characteristic of the security element (1), such that a dynamically changed security element (1) is produced which is available as the current visual appearance for a query by the interrogator.

Abstract: The invention relates to a method and to a device for authenticating and/or identifying persons, objects, or service systems. In said method, a material, a construction, a substance, or a composition, or an image thereof, either changes itself or is actively changed, by means of a physical, chemical, or mechanical influence or feature, such that the resulting structure or feature is unforeseeable. If an image of said material, of the construction, of the substance, or the composition recorded at a later time is compared with the image stored in a storage means, the person and/or the object and/or the medium and/or service system is positively authenticated if the material, the construction, the substance, or the composition has at least partially changed between the two times in comparison with the image stored in the storage means.

Abstract: The present invention relates to a method and an authentication device for authenticating an object or a person by means of a security element, which is individually assigned to the object or to the person and has a plurality of security features. The security element is comprised of a plurality changeable modules with a plurality of surfaces, wherein at least some of the modules have specific security features and single or all modules are individually combined to form a new, changed security element. At the enquiry time-point, the visual appearance or a property of the changed security element is recorded and compared with the reference feature stored in the database, in order to authenticate the object or the person.

Abstract: The present invention relates to a method for authenticating and/or identifying persons, objects, service systems or computer programs, in which a static, unchanging security feature that is characteristic of the person, the object, the service system or the computer program, is created or used, which is subsequently altered under the influence of an unforeseeable factor and thereby converted into a dynamic security feature. Positive authentication is obtained, when the dynamic security feature has at least been partly changed by a dynamic factor between two query times in comparison with the static security feature stored in the storage medium, wherein the static security feature stored in the storage medium corresponds to the most recently updated, altered dynamic security feature from the last query time. Further, the invention relates to an authentication system, in which dynamic security features originate from a static security feature.

Abstract: The invention relates to a method for authenticating and/or identifying a device, a service, a person and/or money in a communication network, consisting of a first communication device and an additional communication device, for example a central database, between which an authentication query is carried out. Initially, a first key is provided in the communication device, which comprises at least one character sequence consisting of individual or several locally modifiable characters which can be dynamically modified in accordance with a measurable variable or an algorithm which is dependent on the measurable variable, rules and/or instructions in the communication device, between two authentication time points. A second key is also provided in the central database or an additional communication subscriber which comprises a character sequence consisting of centrally modifiable characters and optionally non-modifiable characters.

Abstract: The present invention relates to a method for identification a security pattern by converting two-dimensional (2-D) images or a real existing 3-D model into an artificial three-dimensional (3-D) reconstruction via an analysis of the surface structures, colour information (colour and/or colour intensity), and depth information of the detected security pattern. The method is characterized by the following steps: generating an elevation model by determining the surface normal per pixel for the three coordinate axes (x, y, z) from the detected 2-D images or the 3-D model, analyzing the pixel intensity of the detected 2-D images or the 3-D model on the basis of the shadow and the reflection behaviour, and generating the artificial 3-D reconstruction from the pixel intensity, wherein a non-reproducible artificial 3-D surface is generated according to the pixel intensity or the brightness level.

Abstract: The invention relates to an authentication system, comprising a security element (1) having a changing or changeable surface (6), structure, volume, composition, or sequence of characters, an assignment means, which assigns the security element (1) to a person, an object, a medium, or a group of these, a local or central memory device for storing security feature, an interrogator for retrieving a current visual appearance of the security feature, a data synchronisation means for comparing the retrieved visual appearance with the visual appearance of the security element (1) stored in the local or central memory device, wherein an inherent or external trigger means is present, which effects a change at least in some areas of a surface (6), structure or characteristic of the security element (1), such that a dynamically changed security element (1) is produced which is available as the current visual appearance for a query by the interrogator.

Abstract: The invention relates to a method and to a device for authenticating and/or identifying persons, objects, or service systems. In said method, a material, a construction, a substance, or a composition, or an image thereof, either changes itself or is actively changed, by means of a physical, chemical, or mechanical influence or feature, such that the resulting structure or feature is unforeseeable. If an image of said material, of the construction, of the substance, or the composition recorded at a later time is compared with the image stored in a storage means, the person and/or the object and/or the medium and/or service system is positively authenticated if the material, the construction, the substance, or the composition has at least partially changed between the two times in comparison with the image stored in the storage means.

After producing a communication connection (4) between the communication device (1) and an authentication device (2), an authentication request (6) is transmitted from the authentication device (2) to the communication device (1). A unique feature (7) of the user is then acquired and transmitted to the authentication device (2) by acquisition means of the communication device (1), where it is compared to a stored reference feature (30). Upon correspondence, a user identification (10) is transmitted to the communication device (1). The invention further relates to a communication device and an authentication device which are implemented to carry out the method.
