## Abstract

An identity system for the Internet of Things (IOT) that enables users and machines to identify, authenticate and interact with products and collectibles without relying on a third-party-controlled authentication service. The system includes wireless tamperproof tags coupled to products and an open registry database where a chain of ownership of the items is able to be stored. The open registry enables public access to the item identity and data combined with item registration anonymity.

## Claims

### Claim 1

A method of item identity verification using an item open registry, a mobile device, and a plurality of identity tags, the identity tags each storing a private key and a unique identifier and coupled to a separate one of a plurality of physical items, wherein the physical item is associated with a network accessible location and the network accessible location comprises a website, the method comprising: for each physical item of the plurality of physical items:
storing, by the open registry, an entry of the physical item, wherein the entry comprises the unique identifier of the identity tag, a public key of the identity tag, an identifier of the network accessible location and a history of custodianship of the physical item, wherein the public key is associated with the private key stored on the identity tag coupled to the physical item;
broadcasting, by the identity tag, the unique identifier;
monitoring, by the mobile device, the identity tag and receiving, by the mobile device, the unique identifier of the identity tag;
transmitting, by the mobile device, the unique identifier to the open registry;
receiving, by the mobile device, the public key associated with the unique identifier from the open registry;
generating and transmitting, by the mobile device, a challenge message to the identity tag;
generating, by the identity tag, a digital signature by signing the challenge message with the private key;
sending, by the identity tag, the digital signature and the signed challenge message to the mobile device;
authenticating, by the mobile device, the physical item by verifying the digital signature;
retrieving, by the mobile device, the identifier of the network accessible location from the open registry using the unique identifier based on the verification of the digital signature; and
accessing and presenting, by the mobile device, the network accessible location of the physical item using the retrieved identifier of the network accessible location.

### Claim 2 (depends on 1)

The method of claim 1, further comprising
storing, by the open registry, a chain of ownership of the physical item;
retrieving, by the mobile device, the chain of ownership from the open registry using the unique identifier based on the verification of the digital signature; and
presenting, by the mobile device, the chain of ownership of the physical item.

### Claim 3 (depends on 1)

The method of claim 1, further comprising:
receiving, by the open registry, the unique identifier from the mobile device;
looking up, by the open registry, the public key using the received unique identifier; and
transmitting, by the open registry, of the public key to the mobile device.

### Claim 4 (depends on 1)

The method of claim 1, wherein the identity tag is made of a tamperproof fastener physically coupled with a wireless signal receiving/transmitting circuit enveloped by a single contiguous plastic shell, further comprising: coupling of the identity tag to the physical item by the tamperproof fastener.

### Claim 5 (depends on 1)

The method of claim 1, wherein the identity tag is made of a wireless signal receiving/transmitting circuit stitched within a label of the physical item, further comprising: coupling of the tag to the physical item by the label.

### Claim 6 (depends on 1)

The method of claim 1, wherein the identity tag is integrated in an identity of things (IoT) in the form of a circuitry board, microchip, firmware or software.

### Claim 7 (depends on 1)

presenting, by the reader device, the chain of ownership of the physical item.

### Claim 11 (depends on 9)

The method of claim 9, further comprising:
receiving, by the open registry, the unique identifier from the reader device;
looking up, by the open registry, the public key using the received unique identifier; and
transmitting, by the open registry, the public key to the reader device.
