ENHANCED TWO-FACTOR VERIFICATION FOR DEVICE PAIRING

摘要

A novel method for out-of-band key verification that improves on both the usability and the security of the numeric-code method is provided. The method use portions of the generated keys as inputs to perform procedural image generation to produce a visualization at each of the two devices that the user can visually compare and confirm. This visualization can be a static image or a motion animation. The method can uses more of the key data to generate visualizations with more features to reduce the likelihood of false matches. The method can also use less key data to allow for quicker comparison and confirmation.

1. A method comprising:
generating, at a first device, a validation data for secured communication with a second device; generating and displaying a visualization of the validation data to a user of the first device by using data bits in the validation data to compute a location and a zoom level of a window over a pattern, the window identifying a portion of the pattern that serves as the visualization of the validation data; and using the validation data to establish secure communication with the second device after receiving a user validation of the validation data based on the visualization of the validation data.
