Secure display of transaction approval code

A computer program product for securing a display of a device, the computer program product comprising:

• one or more computer readable storage media wherein the computer readable storage medium is not a transitory signal per se, and program instructions stored on the one or more computer readable storage media, the program instructions comprising:
• program instructions to perform an obfuscation action on an image of a display of a first computing device subsequent to initiation of a device-to-device transaction by activating a transaction application of the first computing device;
• program instructions to measure a distance between the first computing device and a second computing device;
• program instructions to determine whether the distance between the first computing device and the second computing device meets a pre-determined threshold distance;
• and
• in response to determining the distance between the first computing device and the second computing device does meet the pre-determined threshold distance, program instructions to deactivate the obfuscation action on the display of the first computing device and display the image directed to the second computing device, confirming the device-to-device transaction.

A computer system for obfuscating an image on a display of a computing device prior to completion of a device-to-device transaction, the computer program product 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 processors, the program instructions comprising:
• program instructions to perform an obfuscation action on an image of a display of a first computing device subsequent to initiation of a device-to-device transaction by activating a transaction application of the first computing device;
• program instructions to measure a distance between the first computing device and a second computing device;
• program instructions to determine whether the distance between the first computing device and the second computing device meets a pre-determined threshold distance;
• and
• in response to determining the distance between the first computing device and the second computing device does meet the pre-determined threshold distance, program instructions to deactivate the obfuscation action on the display of the first computing device and display the image directed to the second computing device, completing the device-to-device transaction.
