Authentication method for product packaging

1. A method for authenticating a product packaging with a mobile device, the method comprising:

capturing, with a digital imaging device attached to the mobile device, a printed optical-machine-readable-code on a surface of the product packaging;

determining in a first captured zone from the captured optical-machine-readable-code a first content and determining if the first content includes an instruction to read an RFID-tag;

executing the instruction with the mobile device and reading from the read RFID-tag a second content, if the first content is determined to include the instruction;

selecting a reproduction model and a digital image to calculate a resemblance of the digital image and a reproduction of the digital image, the reproduction model and the digital image being stored in a memory of the mobile device or in a memory of a server computer connected with a mobile device; and

verifying, on the mobile device or the server computer, with the selected reproduction model if a second captured zone from the captured optical-machine-readable-code is a reproduction of the selected digital image; wherein

the RFID-tag is positioned between the printed optical-machine-readable-code and the surface of the product packaging.

2. The method according to claim 1 , wherein the reproduction model is selected by determining the reproduction model from the first content and/or from the second content.

3. The method according to claim 1 , wherein the digital image includes an anti-copying pattern.

4. The method according to claim 1 , further comprising the steps of:

connecting the mobile device to a database on the mobile device or the server computer;

combining the first content with the second content to a linkage;

executing a query on the database; and

comparing the linkage with the query.

5. The method according to claim 4 , further comprising the steps of:

connecting the mobile device to the server computer;

sending the captured optical-machine-readable-code; and

sending the second content to the server computer; wherein

the steps of determining, selecting, verifying, combining, and comparing are performed on the server computer.

6. The method according to claim 5 , wherein a result from the step of comparing and/or a result from the step of verifying is displayed on the mobile device after the result from the step of comparing and/or the result from the step of verifying is received by the mobile device from the server computer.

7. The method according to claim 6 , wherein a determination in the first captured zone and/or a verification of the second captured zone includes a step of:

color converting the captured optical-machine-readable-code from a device-dependent color space to a device-independent color space.

8. The method according to claim 7 , wherein the first content and/or the second content from the product packaging includes a manufacturing code, a manufacturing date, a manufacturing place, a physical characterization, and/or a manufacturing weight of a product in the product packaging.

9. The method according to claim 8 , wherein the product packaging is selected from the group consisting of ink packaging, food packaging, luxury good packaging, and pharmacy packaging.

10. The method according to claim 9 , wherein the first content and/or the second content is encrypted and the method further comprises the step of:

decrypting the first content and/or the second content.

11. The method according to claim 9 , wherein the first content and/or the second content is data-compressed and the method further comprises the step of:

data-decompressing the first content and/or the second content.

12. The method according to claim 9 , wherein the first content and/or the second content includes a check-sum code and the method further comprises the step of:

checking the check-sum code against the first content and/or the second content.

13. The method according to claim 1 , wherein the mobile device is an NFC-enabled mobile device selected from the group consisting of a mobile computer and a mobile phone.

14. The method according to claim 1 , wherein the first captured zone includes a set of unbroken curves and the first content is embedded by a plurality of N-bit data, N being a non-zero positive integer;

each possible value of the plurality of N-bit data has a thickness and/or length;

the plurality of N-bit data includes a first N-bit data and a second N-bit data, different from the first N-bit data, on a curve of the set of unbroken curves; and

the thickness of the value of the first N-bit data on the curve is different from the thickness of the value of the second N-bit data, and/or the length of the value of the first N-bit data on the curve is different from the length of the value of the second N-bit data.
