Abstract

Claims (55)

1. A system for authenticating an identity document, the system comprising:

a mobile device; and

one or more memory devices comprising instructions that, when executed by one or more processors, cause the one or more processors to perform the following steps:

storing cluster information of two or more clusters on the mobile device, wherein the cluster information of the two or more clusters includes format features that correspond to how barcode information is structured;

decoding a barcode, using the mobile device, to generate barcode data, wherein:

the barcode is on an identification card; and

the barcode data comprises payload data and format data;

parsing the barcode, using the mobile device, to identify the format data;

comparing, using the mobile device, the format data to format features of at least one of the two or more clusters, wherein comparing the format data to format features of at least one of the two or more clusters includes comparing the format data to a vector of constraints of at least one of the two or more clusters; and

predicting, using the mobile device, validity of the identification card, based on comparing the format data of the barcode data to format features of at least one of the two or more clusters.

2. The system of claim 1 , wherein the instructions, when executed, cause the one or more processors to perform the following steps:

predicting, using the mobile device, that the identification card is invalid based on comparing the format data of the barcode data to format features of at least one of the two or more clusters;

initiating a request to a remote identification verification service by transmitting at least a portion of the barcode data from the mobile device to the remote identification verification service, based on predicting the identification card is invalid;

receiving, at the mobile device, a result from the remote identification verification service; and

authenticating, using the mobile device, the identification card presented based on the result from the remote identification verification service.

3. The system of claim 1 , wherein comparing the format data to format features and predicting validity of the identification card are performed on the mobile device, without using an internet connection.

4. The system of claim 1 , wherein the instructions, when executed, cause the one or more processors to update cluster information, on the mobile device, after predicting the validity of the identification card.

5. The system of claim 1 , wherein each of the two or more clusters correspond to a geographical government jurisdiction and/or a version based on a date of issue.

6. A method for authenticating an identity document, the method comprising:

storing cluster information of two or more clusters on a mobile device, wherein the cluster information of the two or more clusters includes format features that correspond to how barcode information is structured;

decoding a barcode, using the mobile device, to generate barcode data, wherein:

the barcode is on an identification card; and

the barcode data comprises payload data and format data;

parsing the barcode, using the mobile device, to identify the format data;

comparing, using the mobile device, the format data to format features of at least one of the two or more clusters, wherein comparing the format data to format features of at least one of the two or more clusters includes comparing the format data to a vector of constraints of at least one of the two or more clusters; and

predicting, using the mobile device, validity of the identification card, based on comparing the format data of the barcode data to format features of at least one of the two or more clusters.

7. The method of claim 6 , comprising:

predicting that the identification card is invalid based on comparing the format data of the barcode data to format features of at least one of the two or more clusters;

initiating a request to a remote identification verification service by transmitting at least a portion of the barcode data to the remote identification verification service, based on predicting the identification card is invalid;

receiving a result from the remote identification verification service; and

authenticating the identification card presented based on the result from the remote identification verification service.

8. The method of claim 7 , wherein the portion of the barcode data includes at least some of the payload data.

9. The method of claim 6 , wherein comparing the format data to format features and predicting validity of the identification card are performed on the mobile device, without using an internet connection.

10. The method of claim 6 , comprising updating cluster information, on the mobile device, after predicting the validity of the identification card.

11. The method of claim 6 , wherein the method comprises removing personally-identifiable information from the payload data from the mobile device.

12. The method of claim 6 , wherein each of the two or more clusters correspond to a geographical government jurisdiction.

13. The method of claim 6 , wherein each of the two or more clusters correspond to a version based on a date of issue.

14. A memory device comprising instructions that, when executed by one or more processors, perform the following steps:

storing cluster information of two or more clusters on a mobile device, wherein the cluster information of the two or more clusters includes format features that correspond to how barcode information is structured;

decoding a barcode, using the mobile device, to generate barcode data, wherein:

the barcode is on an identification card; and

the barcode data comprises payload data and format data;

parsing the barcode, using the mobile device, to identify the format data;

comparing, using the mobile device, the format data to format features of at least one of the two or more clusters, wherein comparing the format data to format features of at least one of the two or more clusters includes comparing the format data to a vector of constraints of at least one of the two or more clusters; and

predicting, using the mobile device, validity of the identification card, based on comparing the format data of the barcode data to format features of at least one of the two or more clusters.

15. The memory device of claim 14 , wherein the instructions, when executed, cause the one or more processors to perform the following steps:

predicting that the identification card is invalid based on comparing the format data of the barcode data to format features of at least one of the two or more clusters;

initiating a request to a remote identification verification service by transmitting at least a portion of the barcode data to the remote identification verification service, based on predicting the identification card is invalid;

receiving a result from the remote identification verification service; and

authenticating the identification card presented based on the result from the remote identification verification service.

16. The memory device of claim 14 , wherein comparing the format data to format features and predicting validity of the identification card are performed on the mobile device, without using an internet connection.

17. The memory device of claim 14 , wherein the instructions, when executed, cause the one or more processors to update cluster information, on the mobile device, after predicting the validity of the identification card.

18. The memory device of claim 14 , wherein the instructions, when executed, cause the one or more processors to remove personally-identifiable information from the payload data from the mobile device.

19. The memory device of claim 14 , wherein each of the two or more clusters correspond to a geographical government jurisdiction.

20. The memory device of claim 14 , wherein each of the two or more clusters correspond to a version based on a date of issue.
