摘要:
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.
摘要:
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. In a further step, a transmission and a comparison of the key stored in the central database and the communication device is carried out.
摘要:
A security element having an electronic display device, particularly a digital display for representing security-relevant information or patterns is provided, wherein the represented information or patterns changes or change over time due to an algorithm and/or external influences. A method for marking, identifying or authenticating objects or living beings is provide, with the living being or object being provided with a security element having an electronic display device, particularly a digital display for representing security-relevant information or patterns, whereby the represented information or patterns changes or change over time due to an algorithm and/or external influences.
