Abstract
Systems and methods for end to end encryption are provided. In example embodiments, a computer accesses an image including a geometric shape. The computer determines that the accessed image includes a candidate shape inside the geometric shape. The computer determines, using the candidate shape, an orientation of the geometric shape. The computer determines a public key of a communication partner device by decoding, based on the determined orientation, data encoded within the geometric shape. The computer receives a message. The computer verifies, based on the public key of the communication partner device, whether the message is from the communication partner device. The computer provides an output including the message and an indication of the communication partner device if the message is verified to be from the communication partner device. The computer provides an output indicating an error if the message is not verified to be from the communication partner device.
