Abstract

The disclosure relates to a method of authenticating a digital credential of a bearer by a validating device, the method including capturing the bearer credential by the validating device and transmitting to a validation service the bearer credential with a validator credential bound to the validating device. The method also includes at the validation service, validating the bearer credential and the validation credential, and if the validator credential is valid, using the bearer credential to access a data item of a digital profile and creating an electronic message for transmission to the validating device, the electronic message indicating the data item and comprising a fresh validator credential generated by the validation service. The method further includes issuing a fresh bearer credential and creating an electronic message to transmit the fresh bearer credential to an address associated with the bearer.

Claims

1. A method of authenticating a digital credential of a bearer by a validating device, the method comprising, in a transaction between the bearer and the validating device:

capturing the bearer credential, by the validating device, from the bearer;

transmitting, from the validating device to a validation service of a digital identity system, the bearer credential with a validator credential bound to the validating device;

at the validation service of the digital identity system, validating the bearer credential and the validator credential, and if the validator credential is valid, using the bearer credential to access a data item of a digital profile of the bearer, the digital profile being bound to the bearer credential, and creating an electronic message for transmission to the validating device, the electronic message indicating the data item and comprising a fresh validator credential generated by the validation service; and

issuing to the bearer a fresh bearer credential and creating an electronic message to transmit the fresh bearer credential to an address associated with the bearer,

wherein the fresh bearer credential is bound to the digital profile of the bearer, and wherein presentation of the fresh bearer credential to the digital identity system by another validating device in a future transaction causes a data item of the digital profile to be rendered available to the another validating device.

2. The method of claim 1, comprising the step of using the validator credential to access a data item of a digital profile associated with the validating device and creating an electronic message for transmission to the bearer, the electronic message indicating a data item for verification by the bearer.

3. The method of claim 1, wherein the electronic message indicates the data item by providing a link to a version of the digital profile held at an addressable memory location identified in the link.

4. The method of claim 2, wherein the electronic message which indicates the data item for verification by the bearer indicates the data item by providing a link to a version of the digital profile associated with the validator at an addressable memory location indicated by the link.

5. The method of claim 1, wherein the data item comprises a visual image of the bearer or validator respectively.

6. The method of claim 1, wherein the fresh bearer credential generated for transmission to the bearer is comprised in a receipt having a transaction identifier.

7. The method of claim 6, wherein the validation service generates a master receipt having the same transaction identifier as the receipt generated for transmission to the bearer, wherein the master receipt is stored in a master receipt book.

8. The method of claim 6 wherein the fresh validator credential is comprised in a non-matching receipt having the same transition identifier.

9. The method of claim 1, wherein the address associated with the bearer comprises an address of a device previously registered by the bearer and stored in association with the bearer credential.

10. The method of claim 1, wherein the step of generating a fresh credential comprises using a randomly generated sequence to generate a fresh credential bound to the digital profile.

11. The method of claim 1, wherein the credentials are one-time only use.

12. A digital identity system comprising:

a validation service comprising;

a network interface configured to transmit and receive electronic messages, and a processor;

wherein the validation service is configured to, in a transaction between the bearer and a validating device, receive from the validating device a digital credential of a bearer, captured at the validating device from the bearer, with a validator credential bound to the validating device, validate the bearer credential and the validator credential, and if the validator credential is valid, using the bearer credential to access a data item of a digital profile of the bearer, the digital profile being bound to the bearer credential, and create an electronic message for transmission to the validating device, the electronic message indicating the data item and comprising a fresh validator credential generated by the validation service; and

wherein the digital identity system is configured to issue a fresh bearer credential to the bearer and create an electronic message to transmit the fresh bearer credential to an address associates with the bearer, wherein the fresh bearer credential is bound to the digital profile of the bearer, and wherein presentation of the fresh bearer credential to the digital identity system by another validating device in a future transaction causes a data item of the digital profile to be rendered available to the other validating device.

13. The digital identity system of claim 12, wherein the digital identity system is configured to use the validator credential to access a data item of a digital profile associated with the validating device and create an electronic message for transmission to the bearer, the electronic message indicating a data item for verification by the bearer.

14. The digital identity system of claim 13, wherein the electronic message indicates a data item by providing a link to a version of the digital profile held at an addressable memory location identified in the link.

15. The digital identity system of claim 14, wherein the electronic message which indicates the data item for verification by the bearer indicates the data item by providing a link to a version of the digital profile associated with the validator at an addressable memory location indicated by the link.

16. The digital identity system of claim 12, wherein the data item comprises a visual image of the bearer or validator respectively.

17. The digital identity system of claim 12, wherein the fresh bearer credential generated for transmission to the bearer is comprised in a receipt having a transaction identifier.

18. The digital identity system of claim 17, wherein the validation service is configured to generate a master receipt having the same transaction identifier as the receipt generated for transmission to the bearer, wherein the master receipt is stored in a master receipt book.

19. The digital identity system of claim 17, wherein the fresh validator credential is comprised in a non-matching receipt having the same transaction identifier.

20. Non-transitory computer-readable media comprising computer readable instructions that, when executed on one or more processors of a digital identity system, configured to cause the digital identity system to, in a transaction between the bearer and the validating device, implement steps of:

receiving from a validating device a credential of a bearer, captured at the validating device from the bearer, with a validator credential bound to the validating device;

validating the bearer credential and the validator credential, and if the validator credential is valid, using the bearer credential to access a data item of a digital profile of the bearer, the digital profile being bound to the bearer credential, and creating an electronic message for transmission to the validating device, the electronic message indicating the data item and comprising a fresh validator credential generated by the validation service;

issuing to the bearer a fresh bearer credential and creating an electronic message to transmit the fresh bearer credential to an address associated with the bearer, wherein the fresh bearer credential is bound to the digital profile of the bearer, and wherein presentation of the fresh bearer credential to the digital identity system by another validating device in a future transaction causes a data item of the digital profile to be rendered available to the another validating device.
