Digital handshake for authentication of devices

A first electronic device for authenticating with a service provider, the first electronic device comprising:

• a display;
• a processor;
• and
• a memory storing instructions that when executed by the processor cause the first electronic device to perform the steps of:
• displaying, at the display, a first image corresponding to a first value stored on the first electronic device, wherein the image is detected by a second electronic device that is associated with a service provider;
• capturing a second image generated by the second electronic device and corresponding to a second value, wherein the second value is based on the first value extracted from the first image by the second electronic device;
• extracting the second value from the second image;
• generating a handshake key using the stored first value and the extracted second value;
• and
• establishing a connection with the second electronic device using the handshake key.

A machine-readable non-transitory storage medium storing instructions that, when executed by a processor included in a first device having a display, cause the first device to carry out steps that include:

• displaying, at the display, a first image corresponding to a first value stored on the first device, wherein the image is detected by a second device that is associated with a service provider;
• capturing a second image generated by the second device and corresponding to a second value, wherein the second value is based on the first value extracted from the first image by the second device;
• extracting the second value from the second image;
• generating a handshake key using the stored first value and the extracted second value;
• and
• establishing a connection with the second device using the handshake key.
