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

What is claimed is:

1. A computer program product comprising:
a computer readable storage medium and program instructions stored on the computer readable storage medium, program instructions executed by a hardware processor comprising:
program instructions to determine that an augmented reality device is implemented by a user;
program instructions to establish a secure connection with said augmented reality device;
program instructions to generate a virtual keypad layout, wherein the program instructions to generate a virtual keypad layout comprise:
program instructions to assign a QR code associated with keys of an external input keypad that maps anchor points for each key of the virtual keypad layout, and
program instructions to generate a randomized virtual keypad over the external input keypad, wherein the virtual keypad layout is visible only to a user associated with said augmented reality device;

program instructions to send said virtual keypad layout to said augmented reality device, for displaying said virtual keypad layout over the external input keypad, wherein the external input keypad comprises keys lacking assigned values, whereby the external input keypad is obscured from viewing from persons not wearing said augmented reality device; and
program instructions to receive a user selection from said virtual keypad layout.

2. The computer program product of claim 1 , wherein the program instructions to determine that the augmented reality device is implemented by a user comprises:
program instructions to detect an identification element associated with the user; and
program instructions to link 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 computer program product of claim 1 , further comprising:
program instructions to, responsive to determining that the augmented reality device is not implemented by said user, display a set of digits on the external input keypad.

4. The computer program product of claim 1 , wherein program instructions to receive the user selection from the virtual keypad layout comprises:
program instructions to detect that said user has selected one or more keys from said virtual keypad layout; and
program instructions to match the user selection with an identification from a database.

5. The computer program product of claim 1 , further comprising:
program instructions to invalidate the virtual keypad layout, responsive to receiving an indication that a transaction is complete.

6. The computer program product of claim 1 , further comprising:
program instructions to automatically invalidate the virtual keypad layout after a preset period of time, prior to receiving the user selection from said virtual keypad layout.

7. The computer program product 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. A computer system comprising:
one or more computer processors;
one or more computer readable storage media;
program instructions stored on the computer readable storage media for execution by at least one of the one or more computer processors, the program instructions comprising:
program instructions to determine that an augmented reality device is implemented by a user;
program instructions to establish a secure connection with said augmented reality device;
program instructions to generate a virtual keypad layout, wherein the program instructions to generate a virtual keypad layout comprise:
program instructions to assign a QR code associated with keys of an external input keypad that maps anchor points for each key of the virtual keypad layout, and
program instructions to generate a randomized virtual keypad over the external input keypad, wherein the virtual keypad layout is visible only to a user associated with said augmented reality device;

program instructions to send said virtual keypad layout to said augmented reality device, for displaying said virtual keypad layout over the external input keypad, wherein the external input keypad comprises keys lacking assigned values, whereby the external input keypad is obscured from viewing from persons not wearing said augmented reality device; and
program instructions to receive a user selection from said virtual keypad layout.

9. The computer system of claim 8 , wherein the program instructions to determine that the augmented reality device is implemented by a user comprises:
program instructions to detect an identification element associated with the user; and
program instructions to link said augmented reality device to a keypad device, said keypad device associated with said external input keypad and said one or more computer processors.

10. The computer system of claim 8 , further comprising:
program instructions to, responsive to determining that the augmented reality device is not implemented by said user, display a set of digits on the external input keypad.

11. The computer system of claim 8 , wherein program instructions to receive the user selection from the virtual keypad layout comprises:
program instructions to detect that said user has selected one or more keys from said virtual keypad layout; and
program instructions to match the user selection with an identification from a database.

12. The computer system of claim 8 , further comprising:
program instructions to invalidate the virtual keypad layout, responsive to receiving an indication that a transaction is complete.

13. The computer system of claim 8 , further comprising:
program instructions to automatically invalidate the virtual keypad layout after a preset period of time, prior to receiving the user selection from said virtual keypad layout.

14. The computer program product of claim 1 , wherein the program instructions to generate a virtual keypad layout, further comprise:
program instructions to randomize the virtual keypad layout using a Caesar cipher encryption.

15. The computer system of claim 8 , wherein the program instructions to generate a virtual keypad layout, further comprise:
program instructions to randomize the virtual keypad layout using a Caesar cipher encryption.
