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.

Claims

1. An authentication system, in which a security element (1) is converted into a dynamic security element (1), comprising

a security element (1) with a changing or a changeable surface (6), a structure, a volume, a composition, or a character string as security features,

a table in a database, which assigns the security element (1) to a person, an object, a medium or a group of these,

a local or a central analog or digital storage medium for storing of a first visual appearance of the security feature,

an optical detection unit to retrieve a second visual appearance of the security feature,

a data comparison software for comparing the retrieved second visual appearance with the first visual appearance of the security feature stored in the local or central storage medium,

a physical or chemical trigger parameter, which causes at least a partial change of a surface (6), a structure, or a property of the security element (1), such that a dynamically modified security element (1) is generated, wherein the second visual appearance of the security feature has changed at least partially compared to the first visual appearance of the security feature and is available for a query by the optical detection unit and is storable in the local or central storage medium, wherein the security element (1) has a partial inner or outer structure, a volume or a material composition, which provides a specific visual appearance for the optical detection unit.

2. The authentication system according to claim 1, wherein the storage medium comprises a service provisioning system, a data, a media, a software, or a string.

3. The authentication system according to claim 1, wherein the security element (1) comprises static, non-variable security features (4) and dynamically variable security features (3), whose profile, structure, composition or visual appearance changes when the trigger parameter reaches a predetermined physical or chemical value.

4. The authentication system according to claim 1, wherein the security element comprises a stretchable material, in which the dynamic security features (3) such as cracks, fissures or recesses are formed, whose diameter or profile can be varied according to the stretch, compression or bending of the material.

5. The authentication system according to claim 1, wherein the security element (1) comprises a first surface with spikes or sharp edges (5), which during movement around a security element (1) formed axis of rotation (7), engage in an adjacent second surface (6) and change their structure.

6. The authentication system according to claim 1, wherein the security element (1) has a first surface (6) provided with static security features (15) integrated therein and a second surface provided with dynamically variable security features (3) integrated therein, and below the first surface (6) of the security element (1) is a rigid base (8) and below the second surface of the security element (1) is a flexible base (8), wherein the flexible base (8) upon activation by the trigger parameter, changes the overlying dynamic security features.

7. The authentication system according to claim 1, wherein the security element (1) has a first surface (6) provided with static security features (15) integrated therein and a second surface provided with dynamically variable security features (3) integrated therein, and the first surface (6) is coated with a protective layer (10) and the second surface (3) is coated with an activation layer (11).

8. The authentication system according to claim 1, wherein the security element (1) comprises a material in which deformable and/or movable voids (16) and/or particulate bodies (12) are located, whose geometric profile, the distance travelled by movement, rotation direction, position and/or visual appearance is/are changeable after activation of the trigger parameter.

9. The authentication system according to claim 1, wherein the security element (1) comprises one or more surface(s) (13) or a volume within a three dimensional structure, which is/are dynamically changeable.

10. The authentication system according to claim 1, wherein the security element (1) comprises an array of several characters, whose position, rotation direction, size, shape and/or colour are changeable by the trigger parameter.

11. The authentication system according to claim 1, wherein the external trigger parameter comprises a measurable physical quantity of an ambient atmosphere, or a behavioural pattern of a person.

12. The authentication system according to claim 11, wherein the trigger parameter itself changes dynamically.

13. The authentication system according to claim 1, wherein a change of the dynamic security features of the security element with a physical parameter as the trigger parameter only occurs if certain conditions are met.

14. The authentication system according to claim 13, wherein the conditions relate to the duration or amplitude of an impulse, which is detected by sensors and transmitted to a corresponding activation device.

15. The authentication system according to claim 1, wherein the trigger parameter is temperature, air pressure, humidity, a colour change of a colour agent, friction or movement.
