Abstract

The method, system, and non-transitory computer-readable medium embodiments described herein provide for identifying invalid identification documents. In various embodiments, an application executing on a user device prompts the user device to transmit an image of the identification document. The application receives an image including the identification document in response to the identification document being within a field of view of a camera of the user device. The identification document includes a plurality of visual elements, and one or more visual elements of the plurality of visual elements are one or more invalidating marks. The application detects a predetermined pattern on the identification document in the image, the predetermined pattern formed from the one or more invalidating marks. The application determines that the identification document is invalid based on the detected predetermined pattern.

First claim

What is claimed is:

1 . A method of validating a document, the method comprising:
detecting a document within a field of view of a camera of a user device, wherein the document includes a plurality of visual elements including a plurality of marks; receiving a plurality of image frames of the document from the camera of the user device; selecting, based on a selected quality threshold, an image frame from the plurality of image frames; detecting, based on the plurality of marks not being aligned with other visual elements in the image frame, a plurality of invalidating marks; detecting the plurality of invalidating marks forming a predetermined pattern on the document; and determining that the document is invalid based on the detected predetermined pattern.

2 . The method of claim 1 , wherein the plurality of invalidating marks comprise a plurality of holes in the document.

3 . The method of claim 1 , wherein the predetermined pattern is predetermined text.

4 . The method of claim 1 , wherein the image frame is selected based on at least one of the plurality of image frames including an image of the document being flat against a dark surface and having all edges visible.

5 . The method of claim 1 , further comprising displaying on the user device a message indicating the document is invalid.

6 . The method of claim 1 , wherein the document is associated with a financial institution.

7 . The method of claim 1 , wherein the document is an identification document.

8 . A system to validate a document, the system comprising:
a user device including at least one memory; and at least one processor coupled to the at least one memory, the at least one processor configured to:
detect a document within a field of view of a camera of a user device, wherein the document includes a plurality of visual elements including a plurality of marks;
receive a plurality of image frames of the document from the camera of the user device;
select, based on a selected quality threshold, an image frame from the plurality of image frames;
detect, based on the plurality of marks not being aligned with other visual elements in the image frame, a plurality of invalidating marks;
detect the plurality of invalidating marks forming a predetermined pattern on the document; and
determine that the document is invalid based on the detected predetermined pattern.

9 . The system of claim 8 , wherein the plurality of invalidating marks comprise a plurality of holes in the document.

10 . The system of claim 8 , wherein the predetermined pattern is predetermined text.

11 . The system of claim 8 , wherein the image frame is selected based on at least one of the plurality of image frames including an image of the document being in-focus, such that it is legible.

12 . The system of claim 8 , wherein the image frame is selected based on at least one of the plurality of image frames including an image of the document being flat against a dark surface and having all edges visible.

13 . The system of claim 8 , wherein the at least one processor is further configured to cause display of a message indicating the document is invalid to the user device.

14 . The system of claim 8 , wherein the document is associated with a financial institution.

15 . A non-transitory computer-readable medium having instructions stored thereon that, when executed by at least one computing device, cause the at least one computing device to perform operations comprising:
detecting a document within a field of view of a camera of a user device, wherein the document includes a plurality of visual elements including a plurality of marks; receiving a plurality of image frames of the document from the camera of the user device; selecting, based on a selected quality threshold, an image frame from the plurality of image frames; detecting, based on the plurality of marks not being aligned with other visual elements in the image frame, a plurality of invalidating marks; detecting the plurality of invalidating marks forming a predetermined pattern on the document; and determining that the document is invalid based on the detected predetermined pattern.

16 . The non-transitory computer-readable medium of claim 15 , wherein the plurality of invalidating marks comprise a plurality of holes in the document.

17 . The non-transitory computer-readable medium of claim 15 , wherein the predetermined pattern is predetermined text.

18 . The non-transitory computer-readable medium of claim 15 , wherein the image frame is selected based on at least one of the plurality of image frames including an image of the document being in-focus, such that it is legible.

19 . The non-transitory computer-readable medium of claim 15 , wherein the image frame is selected based on at least one of the plurality of image frames including an image of the document being flat against a dark surface and having all edges visible.

20 . The non-transitory computer-readable medium of claim 15 , wherein the document is associated with a financial institution.
