Encrypted payment image

Abstract

Embodiments disclosed herein relate to an encrypted payment image. In one embodiment, a processor of a mobile computing device encrypts a binary version of an invoice image with a payment information encryption key. The processor may generate a payment image of the encrypted binary of the invoice image and display the payment image.

1 . A mobile device, comprising:
 a camera configured to capture an invoice image;   a storage configured to store payment account information;   a display;   a processor; and   a computer-readable non-transitory storage medium comprising instructions executable by the hardware processor to:
 authenticate an invoice by encrypting a binary version of the invoice image using the payment account information as an encryption key; and 
 authorize the invoice by displaying on the display an image of the encrypted binary version of the invoice image. 
   
     
     
         2 . The mobile device of  claim 1 , wherein the computer-readable non-transitory storage medium further comprises instructions to display an image of the encrypted binary version of the invoice image comprise instructions to:
 display a barcode image of the encrypted binary version of the invoice image.   
     
     
         3 . The mobile device of  claim 1 , wherein the computer-readable non-transitory storage medium further comprises instructions to:
 decode retail transaction information within the invoice image; and   display the retail transaction image on the display.   
     
     
         4 . The mobile device of  claim 1 , wherein the instructions to authenticate the invoice comprise instructions to:
 authenticate the invoice using a hash-based message authentication code.   
     
     
         5 . The mobile device of  claim 1 , wherein the invoice image comprises at least one of:
 a barcode;   text; and   a halftone image.   
     
     
         6 . The mobile device of  claim 1 , wherein the computer-readable non-transitory storage medium further comprises instructions to:
 generate a user interface to allow a user to select an account for payment of the invoice.   
     
     
         7 . A mobile device, comprising:
 a camera configured to capture an invoice image;   a storage configured to store payment account information;   a display;   a processor; and   a computer-readable non-transitory storage medium comprising instructions executable by the hardware processor to:
 determine, by the mobile computing device, a binary version of the invoice image; 
 sign, by the mobile computing device, the binary version of the invoice image cryptographically with a payment account encryption key; and 
 display, by the mobile computing device, an image of the cryptographically signed binary version of the invoice image. 
   
     
     
         8 . The mobile device of  claim 7 , wherein the instructions to determine the binary version of the invoice image comprise instructions to:
 determine a binary version of an invoice barcode image.   
     
     
         9 . The mobile device of  claim 8 , wherein the computer-readable non-transitory storage medium further comprises instructions to:
 cause a camera to capture the invoice barcode image.   
     
     
         10 . The mobile device of  claim 7 , wherein the computer-readable non-transitory storage medium further comprises instructions to:
 determine, by the mobile computing device, transaction information from the invoice image; and   generate, by the mobile computing device, a user interface to display the transaction information.   
     
     
         11 . The mobile device of  claim 7 , wherein the instructions to display the image of the signed binary version of the invoice image comprise instructions to display at least one of:
 a barcode;   text; and   a halftone image.   
     
     
         12 . The mobile device of  claim 7 , wherein the computer-readable non-transitory storage medium further comprises instructions to:
 generate a user interface to allow a user to select the payment account.   
     
     
         13 . A method, comprising:
 determining, by a mobile computing device, a binary version of an invoice image;   signing, by the mobile computing device, the binary version of the invoice image cryptographically with a payment account encryption key; and   displaying, by the mobile computing device, an image of the cryptographically signed binary version of the invoice image.   
     
     
         14 . The method of  claim 13 , wherein determining the binary version of the invoice image comprises:
 determining a binary version of an invoice barcode image.   
     
     
         15 . The method of  claim 14 , further comprising:
 capturing the invoice barcode image.   
     
     
         16 . The method of  claim 13 , further comprising:
 transmitting, by a retail computing device, the displayed image to a payment entity.   
     
     
         17 . The method of  claim 13 , further comprising:
 determining, by the mobile computing device, transaction information from the invoice image; and   generating, by the mobile computing device, a user interface to display the transaction information.   
     
     
         18 . The method of  claim 13 , wherein displaying an image of the signed binary version of the invoice image comprises displaying at least one of:
 a barcode;   text; and   a halftone image.   
     
     
         19 . The method of  claim 13 , further comprising:
 generating a user interface to allow a user to select an account for payment of the invoice.
