Abstract

A method is disclosed which is performed by at least one first apparatus. In the method, information indicative of at least one characteristic of a franking is obtained. It is determined whether or not the franking is a counterfeit franking and/or a reused franking based on the obtained information or based on the obtained information and based on reference information indicative of at least one characteristic of a franking. The at least one characteristic includes at least one of a physical characteristic of the franking, a visual characteristic of an image provided on the franking, and/or a characteristic based on at least one material of the franking.

First claim

The invention claimed is:

1. An apparatus or system, the apparatus or system comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause an apparatus or system at least to perform and/or control a method comprising:
obtaining or causing obtaining information indicative of at least one characteristic of a franking;
determining or causing determining whether or not the franking is a counterfeit franking and/or a reused franking based on the obtained information and based on reference information indicative of at least one characteristic of a franking;
wherein the at least one characteristic comprises at least one of
a physical characteristic of the franking;
a visual characteristic of an image provided on the franking;
a characteristic based on at least one material of the franking; and

wherein the reference information comprises or corresponds to at least one of the following:
average information indicative of the at least one characteristic of the franking;
at least one unique characteristic of the franking, the unique characteristic uniquely identifying the individual franking.

2. The apparatus or system according to claim 1 , wherein the apparatus or system comprises and/or is connected with a camera.

3. The apparatus or system according to claim 1 , wherein obtaining information indicative of at least one characteristic of a franking comprises acquiring or causing acquiring an image of at least part of the franking.

4. The apparatus or system according to claim 1 , wherein a physical characteristic of the franking comprises at least one of the following:
a physical characteristic of a cutting edge of the franking;
a geometrical shape of the franking;
one or more die cuts present within a body of the franking;
differences in geometry of perforations present along different sides of the franking;
evenness of edges of the franking;
damage of the franking.

5. The apparatus or system according to claim 1 , wherein a visual characteristic of an image provided on the franking comprises or is represented by at least one of:
image resolution;
span of used colors;
image sharpness;
image contrast;
printing quality on pixel level;
printer fingerprint on pixel level;
completeness of an image;
position of image with respect to the franking;
image damage;
image deterioration.

6. The apparatus or system according to claim 1 , wherein the characteristic based on the at least one material of the franking comprises or corresponds to at least one of:
a structure of a paper used for manufacturing the franking;
presence and/or absence of a fluorescence and/or superfluorescent ink in at least part of an image provided on a surface of the franking;
a color appearance of the franking depending on a wavelength of light used for illuminating the franking;
presence of at least one unexpected material.

7. The apparatus or system according to claim 1 , wherein obtaining information indicative of at least one characteristic of a franking comprises acquiring at least one image of a surface of the franking in an ultraviolet and/or in an infrared wavelength range.

8. The apparatus or system according to claim 1 , the method further comprising:
receiving or causing receiving the reference information indicative of the at least one characteristic of a franking from at least one external apparatus in association with identification information of the franking.

9. The apparatus or system according to claim 1 , wherein determining whether or not the franking is a counterfeit franking and/or a reused franking based on the obtained information or based on the obtained information and based on the reference information indicative of at least one characteristic of a franking comprises:
comparing or causing comparing the information indicative of the at least one characteristic of the franking to reference information indicative of the at least one characteristic of the franking.

10. The apparatus or system according to claim 1 , the method further comprising:
extracting or causing extracting a consignment unit to which the franking is applied from a logistics process if it is determined that the franking is a counterfeit franking and/or has been used before.

11. The apparatus or system according to claim 1 , wherein the apparatus or system corresponds to and/or comprises at least one of the following:
an apparatus configured for a logistics process;
a robot;
an Unmanned Aerial Vehicle;
a mobile device;
a network server.

12. The apparatus or system according to claim 1 , wherein the apparatus or system corresponds to and/or comprises a sorting machine and/or a franking machine.

13. The apparatus or system according to claim 1 , wherein determining whether or not the franking is a counterfeit franking and/or a reused franking based on the obtained information or based on the obtained information and based on reference information indicative of at least one characteristic of a franking comprises or corresponds to one or more of:
comparing or causing comparing information indicative of a physical characteristic of a cutting edge of the franking to reference information indicative of the physical characteristic of a cutting edge of a corresponding franking;
comparing or causing comparing information indicative of a visual characteristic of an image provided on the franking to reference information indicative of the visual characteristic of an image provided on a corresponding franking;
comparing or causing comparing information indicative of a characteristic based on the at least one material of the franking to reference information indicative of the characteristic based on the at least one material of the franking.

14. An apparatus or system, the apparatus or system comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause an apparatus or system at least to perform and/or control a method comprising:
obtaining or causing obtaining information indicative of at least one characteristic of at least one franking;
associating or causing associating the information indicative of the at least one characteristic of the at least one franking with reference information indicative of the at least one characteristic of a franking;
wherein the at least one characteristic comprises at least one of
a physical characteristic of the franking;
a visual characteristic of an image provided on the franking;
a characteristic based on at least one material of the franking; and

wherein the reference information comprises or corresponds to at least one of the following:
average information indicative of the at least one characteristic of the franking;
at least one unique characteristic of the franking, the unique characteristic uniquely identifying the individual franking.

15. The apparatus or system according to claim 14 , wherein associating the information indicative of the at least one characteristic of the at least one franking with reference information indicative of the at least one characteristic of a franking comprises at least one of:
storing or causing storing the information indicative of the at least one characteristic of the at least one franking as reference information in association with identification information of the respective at least one franking;
providing or causing providing the information indicativ
