Two-dimensional marker for marking an object, method and system for generating the marker, method and system for generating a marker code, and method and system for authenticating an object

A data processing system for generating a marker, wherein the marker is to be associated with an object, the data processing system comprising:

• at least one processor configured to load software comprising instructions for performing the steps of:
• receiving object data corresponding to the object;
• converting the object data into a marker code;
• generating a marker image based on the marker code, wherein the marker is based on the marker image, and comprises a plurality of line segments each extending between a first end point and a second end point thereof, wherein at least one of the line segments comprises a shape of at least one period of a periodic waveform,
• wherein the object data, the marker code, the marker image and the marker have a one-to-one relationship.

A data processing system for generating object data corresponding to an object being associated with a marker, the data processing system comprising:

• at least one processor configured to load software comprising instructions for performing the steps of:
• receiving a marker image obtained by scanning the marker, wherein the marker comprises a plurality of line segments each extending between a first end point and a second end point thereof, wherein at least one of the line segments comprises a shape of at least one period of a periodic waveform;
• generating a marker code based on the marker image;
• and
• converting the marker code into object data,
• wherein the object data, the marker code, the marker image and the marker have a one-to-one relationship.

A data processing system for identifying and/or authenticating an object, the object being associated with a marker, the data processing system comprising:

• at least one processor configured to load software comprising instructions for performing the steps of:
• receiving a marker image obtained by scanning the marker, wherein the marker comprises a plurality of line segments each extending between a first end point and a second end point thereof, wherein at least one of the line segments comprises a shape of at least one period of a periodic waveform;
• generating a marker code based on the marker image, wherein the marker code, the marker image, and the marker have a one-to-one relationship;
• and
• comparing the generated marker code with each one of a set of authenticated marker codes, and, if the generated marker code is found to be identical to one of the authenticated marker codes, designating the object as being authentic.

A data processing system of identifying and/or authenticating an object, the object being associated with a marker, the data processing system comprising:

• at least one processor configured to load software comprising instructions for performing the steps of:
• receiving a marker image obtained by scanning the marker, wherein the marker comprises a plurality of line segments each extending between a first end point and a second end point thereof, wherein at least one of the line segments comprises a shape of at least one period of a periodic waveform;
• generating a marker code based on the marker image;
• converting the marker code into object data, wherein the object data, the marker code, the marker image and the marker have a one-to-one relationship;
• and
• comparing at least part of the object data with each one of a set of authenticated object data and, if the at least part of the object data is found to be identical to one of the authenticated object data, for designating the object as being identified and/or authentic.
