Abstract

Comparing extracted card data from a continuous scan comprises receiving, by one or more computing devices, a digital scan of a card; obtaining a plurality of images of the card from the digital scan of the physical card; performing an optical character recognition algorithm on each of the plurality of images; comparing results of the application of the optical character recognition algorithm for each of the plurality of images; determining if a configured threshold of the results for each of the plurality of images match each other; and verifying the results when the results for each of the plurality of images match each other. Threshold confidence level for the extracted card data can be employed to determine the accuracy of the extraction. Data is further extracted from blended images and three-dimensional models of the card. Embossed text and holograms in the images may be used to prevent fraud.

First claim

What is claimed is:

1. A computer-implemented method to compare extracted card data using continuous scanning, comprising:
receiving, by one or more computing devices, a digital scan of a card from a camera;
obtaining, by one or more computing devices, a plurality of images of the card from the digital scan of the physical card;
creating, by one or more computing devices, a first three-dimensional model of the card that captures a hologram that is displayed on the card based upon a digital manipulation of the plurality of images;
comparing, by the one or more computing devices, the first three-dimensional model of the card displaying the hologram to a standard three-dimensional model of the card depicting the hologram on the card;
determining, by the one or more computing devices, that perspectives of the first three-dimensional model of the hologram match the standard model of the hologram; and
verifying, by the one or more computing devices, the first three-dimensional model based on the determination that the perspectives of the first three-dimensional model of the hologram match the standard model of the hologram.

2. The method of claim 1 , further comprising:
accessing, by the one or more computing devices, at least one additional digital image of the card based on a determination by the one or more computing devices that the three-dimensional model of the hologram does not match the standard model of the hologram;
creating, by one or more computing devices, a second three-dimensional model of the card that captures the hologram based upon the additional images and at least a portion of the plurality of images;
comparing, by the one or more computing devices, the second three-dimensional model of the hologram to the standard three-dimensional model of the hologram;
determining, by the one or more computing devices, if the perspectives of the second three-dimensional model of the hologram match the standard three-dimensional model of the hologram; and
verifying, by the one or more computing devices, the second three-dimensional model when the perspectives of the second three-dimensional model of the hologram match the standard three-dimensional model of the hologram.

3. The method of claim 2 , wherein the one or more computing devices receive the at least one additional image from the obtained plurality of images.

4. The method of claim 2 , wherein the one or more computing devices receives the at least one additional image via a second scan of the card by the camera.

5. The method of claim 1 , wherein the digital scan is received from a camera.

6. The method of claim 1 , wherein the digital scan comprises a video or a plurality of still images.

7. The method of claim 1 , wherein the card is a credit card, a debit card, an identification card, a loyalty card, an access card, or a stored value card.

8. A computer program product, comprising:
a non-transitory computer-readable storage device having computer-executable program instructions embodied thereon that when executed by a computer cause the computer to compare extracted card data using continuous scanning, the computer-executable program instructions comprising:
computer-executable program instructions to receive a digital scan of a card;
computer-executable program instructions to obtain a plurality of images of the card from the digital scan of the physical card;
computer-executable program instructions to create a first three-dimensional model of the card that captures a hologram that is displayed on the card based upon a digital manipulation of the plurality of images;
computer-executable program instructions to compare the first three-dimensional model of the card displaying the hologram to a standard three-dimensional model of the card depicting the hologram on the card;
computer-executable program instructions to determine that perspectives of the first three-dimensional model of the hologram match the standard model of the hologram; and
computer-executable program instructions to verify the first three-dimensional model based on the determination that the perspectives of the first three-dimensional model of the hologram match the standard model of the hologram.

9. The computer program product of claim 8 , the computer program further comprising:
computer-executable program instructions to access at least one additional digital image of the card;
computer-executable program instructions to create a second three-dimensional model of the card that captures the hologram based upon the additional images and at least a portion of the plurality of images;
computer-executable program instructions to compare the second three-dimensional model of the hologram to the standard three-dimensional model of the hologram; and
computer-executable program instructions to determine if the perspectives of the second three-dimensional model of the hologram match the standard three-dimensional model of the hologram.

10. The computer program product of claim 8 , wherein the computer receives the at least one additional image from the obtained plurality of obtained images.

11. The computer program product of claim 8 , wherein the computer receives the at least one additional image via a second scan of the card.

12. The computer program product of claim 8 , wherein the digital scan is received from a camera.

13. The computer program product of claim 8 , wherein the digital scan comprises a video or a plurality of still images.

14. A system to compare extracted card data, the system comprising:
a storage resource;
a processor communicatively coupled to the storage resource, wherein the processor is configured to execute computer-readable instructions that are stored in the storage resource and that cause the system to:
receive a digital scan of a card;
obtain a plurality of images of the card from the digital scan of the physical card;
create a first three-dimensional model of the card that captures a hologram that is displayed on the card based upon a digital manipulation of the plurality of images
compare the first three-dimensional model of the card displaying the hologram to a standard three-dimensional model of the card depicting the hologram on the card; and
determine that perspectives of the first three-dimensional model of the hologram match the standard model of the hologram.

15. The system of claim 14 , the computer-readable instructions being configured to further cause the system to:
access at least one additional digital image of the card;
create a second three-dimensional model of the card that captures the hologram based upon the additional images and at least a portion of the plurality of images;
compare the second three-dimensional model of the hologram to the standard three-dimensional model of the hologram; and
determine if the perspectives of the second three-dimensional model of the hologram match the standard three-dimensional model of the hologram.

16. The system of claim 15 , wherein the at least one additional image is accessed from the obtained images.

17. The system of claim 14 , wherein the card is a credit card, a debit card, an identification card, a loyalty card, an access card, or a stored value card.
