摘要:
Embodiments of the invention provide a method of reading and verifying a tag based on inherent disorder during a manufacturing process. The method includes using a first reader to take a first reading of an inherent disorder feature of the tag, and using a second reader to take a second reading of the inherent disorder feature of the tag. The method further includes matching the first reading with the second reading, and determining one or more acceptance criteria, wherein at least one of the acceptance criteria is based on whether the first reading and the second reading match within a predetermined threshold. If the acceptance criteria are met, then the tag is accepted, and a fingerprint for the tag is recorded. The invention further provides a method of testing and characterizing a reader of inherent disorder tags during a manufacturing process. The method includes taking a reading of a known inherent disorder tag, using the reading to measure a characteristic of the reader, and storing the measured characteristic for use when reading inherent disorder tags.

摘要:
An identification tag for identifying an object to which the identification tag may be attached or in which the tag may be embedded, as well as to objects that are adapted to be identified. The invention also relates to reading devices for reading identification features that are located in an identification tag. The tags and objects may consist of an engagement track or accommodating recess wherein the engagement track or accommodating recess is designed such that it allows reading of identification features comprised in the tag or object and wherein the engagement track or accommodating recess is designed such that it is essentially complementary in shape to an engagement element of a reading device, wherein the engagement element comprises a reading element adapted for reading the identification features located in the identification tag or object. The identification tag may also comprise an accommodating layer which comprises an accommodating recess.
摘要:
A method of identifying an object having identification information, said identification information being used to verify the object's identity, said method comprising: determining at least one characteristic of a magnetic field of at least a portion of a tag, thereby obtaining a first specific magnetic signal, wherein the tag comprises a substantially non-magnetic host material having pores, wherein at least some of the pores contain a magnetic material, and storing signal information relating to said first specific magnetic signal, said stored signal information forming the identification information of the object.
摘要:
A reading device for identifying a tag or an object adapted to be identified is disclosed. The reading device includes a first reading element for reading a first set of identification features located in the tag or the object adapted to be identified, wherein the first reading element is a magneto-optical reading element; and a second reading element for reading a second set of identification features located in the tag or the object adapted to be identified; wherein the reading device is configured such that a first signal generated from reading the first set of identification features and a second signal generated from reading the second set of identification features are independently used to derive a first signature and a second signature for identifying the tag or object.
摘要:
Disclosed is an object (200) such as a credit card, bank note, document, label, etc which carries an identification layer (103) which contains readable information. The identification layer can include randomly distributed conductive/magnetisable particles (303), semiconductive particle, optically active particles and the like. The identification layer is sandwiched between an upper layer (105) and lower layer (104) to form the object. At least some of the particles are exposed along one edge (102) of the object and can be read by a read head (201) which moves along the edge.
