Abstract
Authentication devices, systems and methods are provided, where an authentication device is applied to an article to be authenticated. The authentication device generates a magnetic signature that is converted into a unique digital value. The digital value is typically used to query an authentication ledger.
Claims19
An authentication device arranged to generate a reliable unique magnetic signature when interrogated with a magnetic reader, the device comprising:
- a plurality of heterogeneous magnetically-responsive microwires;
- and
- a substrate across which the microwires are held;
- wherein:
- the microwires differ from one another based on their magnetic properties;
- and
- the microwires are held in a substantially fixed position relative to one another in an arrangement unique to the authentication device;
- and
- wherein the authentication device presents a scanning zone having an area of less than 20 cm2.

An authentication system, comprising:
- an authentication device suitable for application to an article to be authenticated, the authentication device:
- being arranged to generate a reliable unique magnetic signature when interrogated with a magnetic reader;
- comprising a plurality of heterogeneous magnetically-responsive microwires;
- and
- comprising a substrate across which the microwires are held;
- wherein:
- the microwires differ from one another based on their magnetic properties;
- and
- the microwires are held in a substantially fixed position relative to one another in an arrangement unique to the authentication device;
- and wherein the system further comprises at least one of:
- an article to which the authentication device is applied;
- an authentication ledger that is optionally a cryptographically-secure distributed ledger;
- a magnetic reader for reading the magnetic signature of the authentication device, the reader optionally being a portable handheld reader;
- and
- a convertor for converting the read magnetic signature into a digital value for use in querying the authentication ledger, and
- wherein the authentication device presents a scanning zone having an area of less than 20 cm2.

- converting the read magnetic signature into a digital value;
- and
- using the digital value to query an authentication ledger;
- wherein the authentication device comprises:
- a plurality of heterogeneous magnetically-responsive microwires;
- and
- a substrate across which the microwires are held;
- wherein:
- the microwires differ from one another based on their magnetic properties;
- and
- the microwires are held in a substantially fixed position relative to one another in an arrangement unique to the authentication device, and
- wherein the authentication device presents a scanning zone having an area of less than 20 cm2.
