Abstract
A method of identifying an object having coded data identifying a plurality of fiducials on a surface of the object and a random pattern superimposed with the coded data. The random pattern defines a fingerprint for the object. The method includes the steps of: receiving, in a computer system, fingerprint data from a data reader interacting with the surface, the fingerprint data identifying some of the random pattern and a fiducial; using the fiducial to identify a portion of the random pattern; and identifying, using the identified portion of the random pattern, an object identity.
Claims11
A method of identifying an object, said object comprising coded data identifying a plurality of fiducials on a surface of the object and a random pattern superimposed with the coded data, said random pattern defining at least one fingerprint for the object, wherein said method comprises the steps of:
- receiving, in a computer system, fingerprint data from a data reader interacting with the surface, said fingerprint data identifying at least some of the random pattern and at least one fiducial;
- using the at least one fiducial to identify a portion of the random pattern;
- and
- identifying in the computer system, using the identified portion of the random pattern, an object identity.
A method of interacting with an object, said object comprising coded data identifying a plurality of fiducials on a surface of the object and a random pattern superimposed with the coded data, said random pattern defining at least one fingerprint for the object, wherein said method comprises the steps of:
- sensing at least some of the coded data;
- sensing at least some of the random pattern;
- generating fingerprint data using the sensed coded data and the sensed random pattern, said fingerprint data identifying at least some of the random pattern and at least one fiducial;
- and
- communicating the fingerprint data to a computer system.
A method of recording at least one reference fingerprint for an object, said object having a unique object identity and comprising coded data identifying a plurality of fiducials on a surface of the object and a random pattern superimposed with the coded data, said method comprising the steps of:
- sensing and recording the coded data and the random pattern;
- determining at least one reference fingerprint for the object, the or each reference fingerprint comprising at least a portion of the recorded random pattern and at least one fiducial corresponding to said portion;
- associating the object identity with the or each reference fingerprint.
