Systems and methods for device verification and authentication

Abstract

In methods, systems, and computing devices configured to implement methods of authenticating a computing device, a first computing device and a second computing device may share a dynamically updated shared data set. The first computing device may select elements of the shared data set stored at the first computing device and may generate a rule set for extracting the selected elements from the shared data set. The first computing device may send the rule set to the second computing device, and may generate a first result using the selected elements. The second computing device may extract the selected elements from the shared data set using the rule set, may generate a second result, and may send the second result to the first computing device. The first computing device may determine whether the second computing device is authenticated based on whether the first result matches the second result.
