Abstract

Embodiments of the present invention provide methods and systems for numeric keypad encryption using an augmented reality device. The method may include establishing a secure connection to an augmented reality device. A random keypad layout is generated and sent to the augmented reality device. The random keypad layout is displayed in the augmented reality view over a real-world numeric keypad.

First claim

1 . A method for keypad encryption comprising:
determining, by one or more computer processors, that an augmented reality device is implemented by a user; establishing, by one or more computer processors, a secure connection with said augmented reality device; generating, by one or more computer processors, a virtual keypad layout, wherein generating a virtual keypad layout comprises assigning a QR code to each key of the virtual keypad layout; sending, by one or more computer processors, said virtual keypad layout to said augmented reality device, for displaying said virtual keypad layout over an external input keypad; and receiving, by one or more computer processors, a user selection from said virtual keypad layout.

2 . The method of claim 1 , wherein determining that the augmented reality device is implemented by a user comprises:
detecting, by one or more computer processors, an identification element associated with the user; and linking, by one or more computer processors, said augmented reality device to a keypad device, said keypad device associated with said external input keypad and said one or more computer processors.

3 . The method of claim 1 , further comprising:
responsive to determining that the augmented reality device is not implemented by said user, displaying, by one or more computer processors, a set of digits on the external input keypad.

4 . The method of claim 1 , wherein receiving the user selection from the virtual keypad layout comprises:
detecting, by one or more computer processors, that said user has selected one or more keys from said virtual keypad layout; and matching, by one or more computer processors, the user selection with an identification from a database.

5 . The method of claim 1 , further comprising:
responsive to receiving an indication that a transaction is complete, invalidating the virtual keypad layout.

6 . The method of claim 1 , further comprising:
automatically invalidating, by one or more computer processors, the virtual keypad layout after a preset period of time, prior to receiving the user selection from said virtual keypad layout.

7 . The method of claim 1 , wherein said one or more computer processors use a secure short range wireless network to send said virtual keypad layout to said augmented reality device.

8 . The method of claim 1 , wherein generating a virtual keypad layout, further comprises:
randomizing, by one or more computer processors, the virtual keypad layout, using a Caesar cipher encryption.
