Abstract
The application discloses printed objects including encoded information, and methods, apparatus and systems for authenticating such printed objects. Some such objects, methods and apparatus involve data hiding and/or encoded signals.
Claims31
An image processing method for encoding auxiliary data within a digital image, in which the digital image includes a plurality of line elements, said method comprising:
- determining a dominate angle associated with the plurality of line elements;
- and in a digital space, and using an electronic processor, varying line angles of at least a set of the plurality of line elements relative to the dominate angle, in which the varying line angles conveys the auxiliary data.
An image processing method for encoding information within an image, in which the image includes a plurality of line structures, said method comprising:
- identifying a dominate orientation associated with the plurality of line structures;
- and, using an electronic processor, varying line orientation of at least a set of the plurality of line structures relative to the dominate angle, in which the varying line orientation conveys the information.
A physical object comprising:
- a first surface;
- and
- an image printed on the first surface, the image comprising a plurality of line elements encoding auxiliary data,
- the plurality of line elements comprising a dominate angle associated therewith,
- in which a set of the plurality of line elements comprise varied line angles relative to the dominate angle, and in which the varied line angles convey the auxiliary data.
