Abstract

The invention relates to a method for inspecting a security document (10), the use of an augmented reality system (20) for inspecting a security document (10) as well as an augmented reality system (20). One or more first items of information of the security document (10) are captured by means of an augmented reality system (20), in particular a pair of smartglasses. The one or more first items of information are then checked by comparison with a database (40). Furthermore, one or more of the results of the check of the one or more first items of information are stored and/or one or more of the results of the check of the one or more first items of information are output by means of the augmented reality system (20).

First claim

The invention claimed is:

1. A method for inspecting a security document comprising:
capturing one or more first items of information from the security document with a capturing device provided on a pair of smart glasses of an augmented reality (AR) system, wherein the one or more first items of information is a photograph provided on the security document;
checking the captured one or more first items of information by comparison with a database;
storing one or more results of the check of the one or more first items of information;
outputting the one or more results of the check of the one or more first items of information by means of the AR system;
capturing an optical appearance of an optically variable security feature provided on the security document, the optically variable security feature being generated in an optically capturable manner by diffractive structures, zero-order diffraction structures, blazed gratings, macrostructures, lens structures, microprism structures, mirror surfaces, mat structures, anisotropic or isotropic mat structures or combinations of these structures;
verifying the captured appearance of the optically variable security feature by comparison with a database;
capturing a photograph of a holder of the security document with the capturing device provided on the pair of smart glasses of the augmented reality (AR); and
checking the captured photograph of the holder of the security document by comparison with a database, wherein the one or more first items of information are compared with the captured photograph of the holder of the security document.

2. A method according to claim 1 , wherein one or more symbols, logos, images, signs, alphanumeric characters or numbers are captured as one or more additional items of information.

3. A method according to claim 1 , wherein one or more second items of information are captured from the captured photograph of the document holder, wherein the one or more second items of information are items of biometric information of the head, and are determined by a facial recognition algorithm.

4. A method according to claim 3 , wherein the biometric information comprises one or more parameters which specify a pathognomy, physiognomy and/or physiology of the document holder.

5. A method according to claim 1 , wherein one or more of the captured first items of information are output by means of the AR system in visual form before the check is carried out.

6. A method according to claim 1 , wherein the AR system superimposes one or more of the results of the check on the security document optically by means of an optical overlay.

7. A method according to claim 6 , wherein the one or more of the results of the check superimposed on the security document by means of the optical overlay comprise items of information regarding discrepancies/conflicts on the security document, security features containing discrepancies, items of content information or anatomical-physiological features.

8. A method according to claim 1 , wherein one or more of the results of the check of the one or more first items of information of the security document are output in visual, acoustic and/or tactile form by means of the AR system.

9. A method according to claim 1 , wherein, during the check of one or more of the first items of information, it is checked firstly whether one or more objects are present.

10. A method according to claim 9 , wherein, during the check of one or more of the first items of information, one or more features of at least one object of the one or more objects are determined by means of an image-processing algorithm.

11. A method according to claim 10 , wherein at least one feature of the one or more features is constituted by the contours of the at least one object of the one or more objects and the image-processing algorithm is an edge detection algorithm.

12. A method according to claim 1 , further comprising checking items of information about chronological references to already inspected security documents, hints relating to general circumstances/events, items of information regarding on-site incidents or with locational/personal reference, cross references to further inspections/screenings of the security document, hints relating to the relationship field of the document holder, hints relating to further security features of the security document, hints to manually check the security features and statistics.

13. A method according to claim 1 , wherein the one or more results comprise results about personal data, including the name, the date of birth or the sex of the document holder, place of issue of the security document and validity of the security document.

14. A method according to claim 1 , wherein the document type is determined as at least one result during the step of checking the one or more first items of information by comparison with a database.

15. A method according to claim 1 , wherein the one or more first items of information and/or second items of information are optically captured by means of one or more cameras.

16. A method according to claim 1 , wherein, before the capture of one or more first items of information of the security document by means of the AR system, the illuminance is measured and a light source of the AR system is activated at an illuminance of less than 800 1x.

17. A method according to claim 1 , wherein the comparison with the database takes place via a wireless communication connection.

18. An augmented reality (AR) system for carrying out the method according to claim 1 , which has the following components:
one or more capture devices for capturing the one or more first items of information of the security document;
a control device, wherein the control device is designed such that it checks the one or more first items of information by comparison with a database and stores and/or outputs one or more of the results of the check of the one or more first items of information.

19. An AR system according to claim 18 , wherein the AR system has an infoscreen of a pair of smart glasses, a head-up display or a screen.

20. An AR system according to claim 18 , wherein at least one of the capture devices detects electromagnetic waves in the wavelength range of from 200 nm to 50 μm.

21. An AR system according to claim 18 , wherein at least one of the capture devices is a camera.

22. An AR system according to claim 18 , wherein the AR system has one or more capture devices for capturing one or more second, third and/or fourth items of information.

23. An AR system according to claim 18 , wherein the control device has a communication interface for wirelessly accessing the database.

24. An AR system according to claim 18 , wherein the database and/or parts of the database are stored in a storage medium of the control device.

25. An AR system according to claim 18 , wherein the AR system is a pair of smart glasses.

26. The method according to claim 1 , further comprising displaying instructions as to the relative position or distance the security document is to be held or moved with respect to the capture device of the smart glasses on a display of the smart glasses.

27. The method according to claim 1 , wherein additional items of information are machine-read from the security document optically, electromagnetically, magnetically, electrically and/or electronically, wherein the mach
